The Combined Plate Chamber is a standard manufacture fitting virtually any type of inverted microscope.
As described in UNESCO's Phytoplankton Manual (published 1978) the Combined Plate Chamber allows you to look at sedimented plankton samples from a very short distance. How? Put the sample into a cylinder on top of the rectangular plexiglass plate with a thin base plate, let the fixed plankton concentrate and after sedimentation simply push the cylinder with excess liquid aside. The handling support underneath the plate will collect the extra water from the cylinder. You can now take the plate and examine the sample under an inverted microscope. Three calibrated cylinder sizes are provided with each set allowing to analyze different sample volumes.
The basic kit includes a set of cylinders 10 / 50 / 100 ml. Complete with cover plates, also base plates and handling support. The complete kit includes in addition a cylinder of 25 ml, and additional cover and base plates. Items can be purchased separately too.
The Base Plate Set, includes the Base Plate, the Threaded Ring and the Ring Detacher.

Intended for shallow or deep waters, these bottles are called “horizontal” because they descend, parallel to the bottom. They are pulled sideways just before closing by the operator. This ensures a representative water sample for that specific depth. They are ideal for sampling at the thermocline, at other stratification levels, or just above the bottom sediments. These popular and versatile bottles come in your choice of transparent acrylic or opaque PVC. PVC is more durable and less costly, but the acrylic allows you to view the bottle contents immediately.
Alpha samplers are not suitable for chemical analysis of contents due to the potential for contamination (i.e. by mercury and phosphorus) by the materials in the sampler's construction. For chemical analysis, choose our Beta or suggested Kemmerer water samplers.
This sampler requires a messenger and line (included in kits) for operation. A thermometer can be mounted inside acrylic Alpha bottles.
NOTE: Volume may vary slightly. It is recommended that you verify the exact volume of your bottle prior to use.

Designed for trace metal sampling. Also may be used for organic sampling to concentrations of mg/L. When running metal, organic, or any other chemical analyses, it is best to run a blank on the sampler prior to use.
This bottle is excellent for near off-shore (to 200 m) trace metal sampling, since there are no metal parts to touch your sample. You avoid the metallic ion contamination that can cause major errors in algal assays or productivity. Beta Van Dorn bottles have rigid, white plastic end seals for clean sealing. The bottle ends are machined to fit foam silicone gaskets. Amber latex tubing, which does not leach measurable amounts of metal, closes the bottle. Beta™ bottles feature a nylon safety line connecting the end seals, so if the closing tube breaks, you’re less likely to lose your expensive seals. This is why Beta bottles have an excellent track record in a wide variety of field conditions.
This sampler requires a messenger and line (included in kits) for operation. It is not suitable for series sampling. A thermometer can be mounted inside acrylic Beta bottles.
NOTE: Volume may vary slightly. It is recommended that you verify the exact volume of your bottle prior to use.

Alpha™ Van Dorn-style bottles have flexible, plunger-like blue polyurethane end seals for reliable sealing. Black latex tubing is used to close the bottle because it better resists decay in sunlight and in water than amber tubing. It is an extremely strong elastic material but may leach a small amount of heavy metals or other contaminants. The end seals may leach trace amounts of mercury into the water sample in the range of 20 - 450 ng/L (nanograms per liter). End seals may also leach phosphorus in small amounts.
When tripped by a messenger, the urethane end seals snap tightly onto each end of the cylinder, producing an almost leakproof seal. A small amount of sample is always lost until a slight vacuum forms inside as the sealed sampler is lifted. Alpha™ bottles feature a stainless steel trip head for durability and high performance. Nylon safety line connects the end seals to hold them in place even if the latex tubing breaks.
Use vertical bottles in mildly corrosive water, marine water and water with large amounts of suspended solids or adhesive colloidal solids to collect plankton and floating sediments. The wide mouth collects a true water sample with no contamination from other water levels. During descent, the open mouth does not restrict water flow. This makes them particularly suitable for collecting plankton, floating sediments and for use where metallic ion avoidance is desirable. Your choice of transparent acrylic or more durable opaque PVC.
Alpha samplers are not suitable for trace metal analysis due to the potential for contamination (i.e. mercury and phosphorus) by the materials in the sampler’s end seals. For trace metal analysis, choose the beta bottle water samplers.
A thermometer can be mounted inside acrylic alpha bottles.
NOTE: Volume may vary slightly. It is recommended that you verify the exact volume of your bottle prior to use.

ICES standard for phytoplankton primary production measurements.
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 photosynthesis. The ability to measure this process is of great importance when assessing marine pelagic systems. In practice the best way to measure photosynthesis is to look at the absorption of carbon dioxide. The high sensitivity of carbon dioxide absorption measurements allows to use this method under all circumstances. Neither low or very high algal concentrations nor low light conditions and low temperatures are restrictions for this method.
Based on the 14C method, using the absorption of the radio-active 14C isotope of carbon (Steemann-Nielsen, 1952), the ICES Incubator is the ICES standard for phytoplankton primary production measurements.The incubator shown here has been mainly developed for monitoring purposes. It should be used preferably for water samples taken from a mixed water layer with a fixed temperature. 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 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 can be switched individually. For higher irradiance levels a second illumination unit can be mounted onto the ground plate of the ICES Incubator.

The Bottom Sampler acc. to Van Veen is a qualitative sampler to achieve low-disturbed sediment samples in soft or medium hard grounds from any desired depth. It consists of two clamshell jaws connected by a hinge. During descent both levers are locked wide apart and the jaws are open. Upon touching the water bed the locking mechanism is released and when the rope is pulled taut to raise the sampler the jaws close. During retrieval the jaws are holding the sample and prevent sample wash-out. Additional flaps on top of the heavy version 437 333 allow to inspect the sample before retrieving.

This economical water level indicator is ideal for measuring the water level of wells, bore holes, and standpipes. It signals when water is reached with accuracies to 1/100" of a foot or 1 mm. We use a high quality polyethylene tape, indeibly heat stamped with markings in engineering scale. The tape is reinforced with Kevlar fibers and flexible enough to wind smoothly onto the nylon reel and hangs straight in the well. No on/off switch is needed since, when contact is made, the water shorts the probe to complete a circuit.
Buy with confidence knowing that your quality water level indicator tape will perform over the long term. It is backed by a three year warranty.
The Tape: Kevlar reinforced polyethylene dog bone section with stainless steel conductors. Lengths up to 100 m are available.
The Probe: A 6 mm (5/8”) diameter, 19 mm (7 ½”) long probe of stainless steel and Teflon. The probe has no holes or recesses which might trap contaminants and is water tight to the full depth of the tape. An optional non-submersible 3/8 inch diameter probe is available upon request. (Note:The 3/8” (10 mm) probe should not be used to sound the well).
The Electronics: The fully encapsulated circuitry is protected against dirt and moisture.
The Reel: A tough nylon or aluminum reel mounted on a sturdy powder coated steel frame. A soft vinyl hand grip, ergonomic reel lock and casing hangar are seamlessly incorporated in the frame.
