Water Samplers
The Water Sampler LIMNOS is an approved and
uncomplicated instrument to take water samples up
to 30 m depth.
The LIMNOS Water Sampler consists of the holder
device made of PVC and exchangeable 1000 ml
glass bottles as sampling vessels.
The LIMNOS Water Sampler is attached to a wire
and lowered into the water in closed condition in
order to prevent sample contamination by surface
water. The sampler is opened by means of a
messenger upon reaching the desired water depth.
When the messenger hits the anvil, the silicone
tubings spring up to allow water to move in and the
air to leave the bottle.
For investigations of the sample, the glass bottles
are taken from the holder device, so that the sample
cannot be falsified by pouring from one vessel to
another.

water depth.
The slim shape allows the sampling from tubes as small
as 80 mm diameter.
Special feature of this water sampler is the possibility
to sterilize the instrument for sampling (auto-clavetreatment).
The MICROS Water Sampler consists of a frame made
of stainless steel, a bottle holder of Teflon with silicone
tubings and an exchangeable glass bottle with 500 ml
capacity as sampling vessel.
The MICROS Water Sampler is attached to a wire and
lowered into the water in closed condition (with silicone
tubings snapped off) in order to prevent sample contamination by surface water. The sampler is opened
by means of a messenger upon reaching the desired
water depth. When the messenger hits the anvil, the
silicone tubings spring up to allow water to move in
and the air to leave the bottle.

Water Samplers
Standard Water Sampler acc. to Ruttner
With this handy and versatile apparatus, water
samples can be taken from any desired depth. The
closing mechanism of the sampler has proved itself
to be most satisfactory over many years; the water
sampler is of simple and practical design and guarantees reliable results.
The Standard Water Sampler, still open, is lowered
by rope into the water. Upon reaching the desired
depth, the messenger is let down on the rope. When
it strikes the Standard Water Sampler, the closing
mechanism is released and the lids of the sampling
tube close. A thermometer ranging from -2° to +30°C,
indicates the temperature of the sample; the temperature can easily be read through the plastic tube
of the sampler. The water sample can be drawn off
through the discharge cock in the lower lid for the
various analyses.

MERCOS Water Sampler
The MERCOS Water Sampler is an approved and
uncomplicated instrument to take water samples for
ultratrace metal analysis as well as for microbiological investigations.
The MERCOS Sampler consists of the holder device
and exchangeable 500 ml Teflon Bottles as sampling
vessels which can be used up to 30 m water depth.
All fittings are made of titanium.
The MERCOS Sampler is attached to a plastic-coated
steel hydrographic wire and lowered into the water in
closed configuration in order to prevent sample contamination by surface water. The sampler is opened by
means of a plastic-covered messenger upon reaching the desired water depth. When the messenger
hits the anvil, the silicone tubings spring up to allow
water to move in and the air to leave the bottle. In case
of serial operation, a second messenger for release
of the next sampler is given free at the same time.
For the determination of tracer elements in seawater
the system
Sampling Bottle=Storage Bottle = Reaction Vessel
is realized, so that the samples cannot be falsified by
pouring from one vessel to another.
In order to sterilize the bottles for microbiological investigations the Teflon Bottles incl. coupling pieces and
silicone tubings can easily be taken from the holder.

Water Samplers
Plastic Water Sampler PWS
The Plastic Water Sampler PWS features all plastic
(PVC) constructions with a free flushing design by
large inlets.The sampling tube is completely metal-free.
The end stoppers of the sampler are connected by a
strong latex rubber tubing. A messenger dropped
down the wire from the surface releases the end stoppers for closure. The PWS can be used as a series
water sampler and is designed to release a second
messenger below the sampler in order to actuate a
series of samplers along the wire.
When operated as a single instrument on the wire, we
recommend to use a Centered Mounting Rack which
holds the sampler in a vertical position.
Water may be drained from the sampler by opening
the stop cock at the lower end.

Free Flow Water Sampler
The Free Flow Water Sampler is an innovative design
which has been developped in co-operation with the
Institut für Ostseeforschung, Warnemünde (Germany).
An outstanding feature of the Free Flow Water Sampler
is the free-flushing construction of the sampling tube
where no cone or ball-valve hinders the flow of the
water through the tube.
The Free Flow Water Sampler is made of plastic (PVC)
and the sampling tube is completely metal-free. The
end stoppers are connected by a strong latex rubber
tubing. Upon reaching the desired water depth the
sampler is closed by a messenger dropped down the
wire.
The Free Flow Water Sampler can also be used in nearly
all multi sampler systems (Multi Water Sampler, Rosette,
Carousel). The free-flushing design avoids the retarding effect, so that the sample corresponds to the
parallel measured data of a CTD Probe.
A second messenger below the sampler can be released in order to actuate a series of samplers along
the wire.
Water may be drained from the sampler by opening
the stop cock at the lower end.

Water Samplers
Universal Water Sampler
This Universal Water Sampler has been developed
as a combination of many standard instruments,
incorporating their assets and eliminating their
shortcomings.
A new kind of lid attachment and tightening guarantee it to be absolutely leak-proof. Outlet and air-inlet
faucets facilitate easy removal of the sample. The lids
are arrested automatically in an open position and do
not hinder the free flow of water through the completely open tube. This prevents clogging or bobbing
and guarantees that the water is taken from the
exact sampling depth desired.
When used as a single instrument on the wire, we
All inside parts are completely metal free, so that the
water sample is uncontaminated and suitable even
for electrolytic tests. The Universal Water Sampler
can be used as a series water sampler and is
designed to release a second messenger down the
wire below the sampler in order to actuate a series of
samplers along the wire.
If desired, the Universal Water Sampler can be
delivered as a Plankton Sampler with a transparent
plastic tube instead of the non-transparent tube.

Water Samplers
Oil Sampler
Horizontal Water Sampler
The Horizontal Water Sampler has been mainly
designed for near-bottom sampling of flowing or
stagnant waters and allows to take samples for
examination of the sediment and silt carried along
by the current.
The Horizontal Water Sampler can be attached to
any line or wire up to 6 mm ( 1/4 ") in diameter.
Water samples can be taken from any desired depth.
When lowered for sampling, the sampling tube is kept
completely open, allowing the water with its sediment
and silt to flow through it undisturbed. The cylinder is
held parallel to the current by a stabilizing rudder.
The lids are arrested in an open position and do not
hinder the free flow of water through the completely
open sampling tube until released by a messenger.
An approved lid attachment and tightening guarantee
the sampler to be absolutely leak-proof.
The sampling tube is metal free, so that the water
sample is uncontaminated. Outlet and air-inlet faucets facilitate the easy removal of the sample.
A messenger-operated release device closes the
sampler when the desired sampling depth has been
reached. The water sample can subsequently be
examined in the laboratory to determine the weight,
particle size of the sediment, mineral components etc.
The non-transparent sampling tube prevents light
from reaching the trapped organisms, as required in
productivity studies. The Horizontal Water Sampler
can also be delivered with a clear transparent plastic
tube which allows visual examination of the contents.

The Oil Sampler acc.to Schomaker is designed to collect an oil layer which contaminates the water surface.
This instrument has been developed by Deutsches
Hydrografisches Institut (DHI) and, for the first time,
allows to keep the part of water in such samples
small and to collect sufficient oil for the determination.
The operation and handling of the instrument is quite
simple:
The sampler is thrown onto the water surface and
held by a Nylon line. The floating bodies bring the oil
sampler into the right position so that the oil sample
flows in a layer of only a few millimeters thickness
through the inlet funnel into the glass bottle. The collected sample has a volume of approx. 150 ml. The
instrument is pulled out of the water by means of the
Nylon line, the glass bottle is screwed off and the
sampling dates are written onto the label.

to take automatically up to 10 water samples in depths
up to 30 metres.
The system is equipped with 10 Duran glass bottles
of 1 litre capacity each. The bottles are screwed into
a Limnos head and attached to the base plate.
When the system is lowered to the desired water
depth all bottles are closed. They are opened one
after the other according to the preselected time
intervals. When the bottles are filled with water, they
are closed automatically by integrated ball valves.
The bottom anchoring system offers the possibility
to choose the water depth and, if required, change
the depth with each operation. The system can be
handled by one person. As marking at the water
surface a float in the size of a handball is used.

with the water bed, the locking mechanism is released and when the rope is pulled taut to raise the
sampler, the jaws close.

Sediment Sieve Net
For sieving samples taken by Bottom Samplers. Consisting of a galvanized steel frame 40 x 25 (cm); a net
bag of synthetic material with 250 microns mesh size
(other mesh sizes available on request) and two carrying ropes of Nylon.
Sediment Corer
Sediment Corer
Designed to obtain samples from soft, sandy and
medium-hard bottoms.
The Sediment Corer is easy to handle and can be
operated manually with a push rod in shallow waters
as well as in greater water depths by using a rope.
The exchangeable core tube has a length of 600 mm
and an inner diameter of 72 mm.
When the corer is dropped into the water, the plastic
valve flap on the top of the transparent plexiglass
tube is held open and ensures free flow of the water
through the corer tube.
The corer is pushed by hand into the sediment (using
the offered transverse bar or a rod) or penetrates into
the bottom by its own weight (using a rope or wire).
When the desired sample has been taken and the
corer is lifted out of the sediment, the water pressure
onto the valve flap closes the tube during hieving.
Upward movement creates a vacuum, so that the
sediment sample is retained in the tube and cannot
get lost as the corer is retrieved.
After raising the corer out of the water, the supplied
piston is put into the lower end of the tube. The cage
with rope stirrup is taken off and the tube with the
core sample is placed onto the piston.
When the tube is now pressed onto the piston, the
core sample can be removed for examination.

Plankton Nets
Plankton Nets acc. to Apstein
The Plankton Nets acc. to Apstein, used in limnological investigations, are manufactured in various
shapes® and sizes.
MOnyl synthetic tissue is employed as sieve material. Plastic (ABS) Cowls are used for quantitative nets.
A minimum of service is needed since all metal parts
are protected against corrosion. Rotting of the textile,
as is usual with
silk gauze, is impossible. The mesh
®
of this MOnyl synthetic tissue does not change by
swelling of the threads, as is the case with silk. The
standard mesh size of the Plankton Nets acc. to
Apstein is 55 micron, which is used for the collection
of Phytoplankton. For collection of Zooplankton the
nets are available with a mesh size of 335 microns.
For special requirements, each net can be delivered,
without any change in price, with a mesh size as
stated in the table below:

The Hamburg Plankton Net is a modification of the
Isaacs-Kidd-Midwatertrawl for collection of larger
quantities of plankton, for instance, necessary for
the detection of tracer elements or radiochemical
analysis of radionuclides.
The Hamburg Plankton Net is equipped with a net
bag of MOnyl® with 500 micron mesh size. The overall length of the net is 10 metres.
When the Hamburg Plankton Net is towed, the drag
to the fine-meshed net is supported by a coarsemeshed covering net and 5 Nylon ropes along the
net.
For the security of the Hamburg Plankton Net a predetermined breaking-point has been constructed
into the bridle, which makes the net collaps when
the dynamic pressure becomes too strong.
The Hamburg Plankton Net is beeing towed at a
speed of 0.5 up to 4 knots. It can be used in each
desired depth. Even under wind forces 7- 8 it has
been operated
successfully.
th
th
On the 44 and 45 research cruise of the German
Research Vessel ”Walter Herwig” to Iceland the
Hamburg Plankton Net was used with excellent
results. So in hauls of 0.5 to 2 hours 14 - 35 kgs of
pure plankton were collected. These quantities
have been platefrosted and are sufficient for radiochemical analysis. In only 16 hauls of the Hamburg
Plankton Net more than 200 kgs frosted plankton
plates have been collected.

Multi Plankton Sampler MultiNet®
The Sytem
Sampling sea and ocean at its best - with the improved
MultiNet® generation of the Multiple Plankton Sampler,
the worlds leading sampling system for horizontal
and vertical collections in successive water layers.
For horizontal collections the MultiNet® is used with a
V-Fin Depth Depressor, to carry out vertical collections,
a stainless steel support is securely attached to the
bucket holder and enables a quick lowering to depth.
Equipped with 5 resp. 9 net bags the MultiNet® can
be delivered in 3 sizes (apertures) : Mini (0.125 m2),
Midi (0.25 m2) and Maxi (0.5 m2).
Operation:
In its initial position the MultiNet® is brought to water
with all net bags closed. The water flows freely
through the frame allowing to lower it to the greatest
desired depth with high paying out speed where the
first net bag is opened by push button control from
the Deck Command Unit. At the end of the desired
period of horizontal collection resp. after passing the
desired depth interval in case of vertical operation,
the first net bag is closed by a second command.
The second net is opened simultaneously. This
procedure is repeated for the remaining net bags,
while the Deck Command Unit indicates the number
of the active net bag. During operations of Mini and
Midi versions the last net (No. 5) remains open, it
collects plankton from the smallest desired depth up
to the water surface. During operations of the Maxi
version the last net (No. 9) can be closed before
reaching the water surface.
The system consists of a mains powered Deck
Command Unit and a stainless steel frame with
canvas part to which 5 (9) net bags are attached by
means of zip fasteners. The net bags are opened
and closed by means of an arrangement of levers
which are triggered by a battery powered Motor Unit.
The commands for actuation of the net bags are
given via single or multi-conductor cable (not included
in our scope of delivery) between the Underwater
Unit and the Deck Command Unit.
A wide selection of mesh sizes for the net bags is
available to meet the requirements of all standard
and non-standard applications. For common horizontal collections a mesh size of 300 microns (mesh sizes
from 100 to 500 microns available ) is recommended,
for vertical collections mesh sizes from 55 to 500 micron
are applicable.
An integrated Pressure Sensor (measuring range
according to customer’s requirements) allows continuous supervision of the actual operating depth
which is indicated together with all relevant system
data at the LCD-display of the Deck Command Unit.
Two Electronic Flow Meters (option) with automatic
angle compensation can be mounted to the Underwater Unit: one inside the opening of the Underwater
Unit for the determination of the amount of water
passing through the opened nets, one outside the
opening for the determination of clogging effects.
Options:
• Offline-Set
In case that a conducting cable is not available on
board of the vessel an Offline-Set is available which
enables to pre-programme the required sampling
depths via personal computer. With the Offline-Set
the activation of the net bags is carried out automatically according to the pre-selected depth intervals.
All measuring data are stored inside the Offline-Set
during the operation and can be read by a PC when
the MultiNet® is back on board.
• CT-Set
Together with the optional CT-Set the system offers
the full capability of a state-of-the-art oceanographic
Multi Parameter Probe.
The CT-Set consists of one conductivity sensor, one
temperature sensor and an additional electronics
board which are completely integrated into the Motor
Unit of the MultiNet®.
From the CTD data the system computes salinity,
density and sound velocity according to UNESCO
formulas.
• Additional sensors of various parameters
• Data memory up to 4 MByte
• Battery powered Hand-Terminal, special version for
online operations to replace the mains operated Deck
Command Unit when no mains supply is available.
• Special version for operational depths down to
6000 metres

The Visibility Disc is equipped with a rope of 3 metres
length. There are 10 marks in distances of 200 mm
on the first 2 metres above the disc.
The Visibility Disc is lowered into the water and reading of the depth is made by means of the marks at
the rope when the disc is no longer visible in the
water.
It is lowered another 0.5 m and then heaved slowly
again. The second reading is made when the disc
becomes discernible.
Now the arithmetic mean from both readings has to
be made to determine the visibility depth.

Electronic Flow Meter E-Flow
The Electronic Flow Meter E-Flow is designed to
measure the amount of water passing through a
plankton net.
The 6 digit LCD display shows the towing distance
in metres.
Thus the water volume can be easily calculated by
multiplication of the measured value (metres) with
the opening area of the plankton net.
Due to the indisturbed flow of the impeller from the
front a high measuring accuracy even in case of low
water velocities (from 0.1 m/s) is guaranteed. A flow
from the backside does not influence the measuring
value.
The counter can be reset by a turning knob to 0.
The instrument is maintenance-free. The only movable
part is the exchangeable impeller.
The built-in Lithium battery allows a continuous
operation of 5 years.

environments with relative high vertical particulate
flux value. The instrument does not need heavy
moorings and can be easily deployed and recovered
from smaller vessels. Two wide clamps simplify the
use of it in vertical series attached to the same
mooring line.
The Sediment Trap is available in single or multi bottle
versions. Each trap is equipped with a dismountable
buffle grid at the opening to avoid washing out of the
sediment from the upper part of the cylinder. The inside of the trap is completely metal-free. The water
above the collecting bottle can be let off via two drain
cocks. The transparent funnel bottom enables to
check for resuspension of sediment from the collecting bottle after recovery.

Multi Sediment Trap
The Multi Sediment Trap has been designed as light
and handy instrument for autonomous operation in
lakes, continental shelf and aquatic environments with
relative high vertical particulate flux value. It has proven
its reliability during numerous long-time operations in
arctic, antarctic, tropic and sub-tropic environments.
The instrument does not need heavy moorings and
can be easily deployed and recovered from smaller
vessels.
The control device of the Multi Sediment Trap allows
time dependent operations of more than one year
duration.
The cylindrical trap is equipped with a dismountable
buffle grid at the opening to avoid washing out of the
sediment from the upper part of the cylinder. The inside
of the trap is completely metal-free.
The collecting bottles of the Multi Sediment Trap are
isolated from the surrounding environment when
they are inactive. During deployment and recovery
operations the trap bottom is open allowing a free
flow through the body.

Dipping Bar
Dipping Bar acc. to Jens (DBGM)
for the quick and secure determination of the current
speed in shallow waters. By means of the Dipping Bar
acc. to Jens the current speeds of streams, channels
and small rivers up to 60 cm water depth can be
measured. The Dipping Bar has, besides its sturdy
construction and simple operation, the advantage
that with one single and short measurement the
average current of a vertical measuring line can be
determined. Therefore, the quantity of water of a
discharge section can be ascertained quickly and
secure.
The Dipping Bar acc. to Jens is constructed after the
principle of a torque balance; it takes up all individual
current speeds of the vertical measuring line integratingly. The powers operating on the measuring rod
produce a turning moment and distract the measuring
rod away from the vertical line. By means of an
adjustable weight rod a counter turning moment is
produced so far that the measuring rod is brought
back into the vertical line. From the division on the
weight rod there can be read the figure which is
equivalent to the adjusted turning moment. This
figure and the corresponding immersion depth are
typed into the programmed calculator. The display
indicates the current speed of the actual measuring
point in cm/sec.
Additionally, by linear approximation covering some
measuring points over a section of a running water,
the calculator delivers the discharge quantity of the
complete section in m3/sec.

ICES Incubator
One of the most important marine processes is the
formation of organic material resulting from the interaction of carbon dioxide, water and sunlight, a process
known as photo-synthesis. The ability to measure
this process is of great importance when accessing
marine pelagic systems. In practice the most sensitive
method for measurements of photosynthesis is to
measure the absorption of carbon dioxide. The high
sensitivity of carbon dioxide absorption measurements
allows the use of this method under all circumstances,
at low and very high algal concentrations and under
low light and temperature conditions.
Based on the 14C method, using the absorption of
the radio-active 14C isotope of carbon (SteemannNielsen, 1952), the ICES Incubator is the ICES standard incubator for phytoplankton primary production
measurements.
The incubator shown here has been mainly developed
for monitoring purposes. It should be used preferentially for water samples taken from a mixed water
layer which has a fixed temperature. For calculations
of productivity per square meter additional data on
vertical water attenuation are needed as well as daily
irradiance values. Additional measurements of the
amount of phytoplankton (based on chlorophyll-a
concentration measurements) should be carried out
for interpretation purposes.
The ICES Incubator consists of an illuminated transparent plexiglass tank incorporating a turning wheel
on which 12 experimental bottles can be clamped.
The tank is filled with water which is set in motion by
an adjustable circulating pump. Thus the turning
wheel is set in rotation at speeds up to 10 rpm with
the experimental bottles acting as paddles. Tank
connections for a second water circulation allow for
450 000
temperature adjustments of the water by using external
tempering equipment.
The 12 experimental bottles of 50 ml capacity each
have different optical coatings, so that each bottle
has individual transmission rates and thus generating
a number of 12 different irradiance (or light intensity)
levels.
The illumination unit is equipped with 10 fluorescent
tubes with a wave spectrum according to ICES
specifications, each one of which can be switched
individually.
For higher irradiance levels a second illumination unit
can be mounted onto the ground plate of the ICES
Incubator.
