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.

Tubular Plankton Chambers are used for microscopic analysis of plankton samples. The sedimentation process is carried out inside the original inspection cylinder to avoid any falsification of the samples during handling. The chamber consists of a plexiglass tube with an unscrewable metal base ring holding a thin base plate of just 0.2 mm. Analysis of the sample is made on inverted microscopes. Our scope of delivery includes one chamber, one glass cover plate and a set of 50 glass base plates.

The Mechanical Flow Meter with back-run stop is a specialized precision instrument designed for the most demanding oceanographic and limnological research. Its primary application is the accurate determination of the volume of water passing through a plankton net, although its robust design also makes it ideal for stationary monitoring in rivers and outfalls. By utilizing a three-blade impeller directly coupled to a non-resetting five-digit counter, the device provides a reliable mechanical record of every revolution during deployment.
Engineered for vertical operations, the "back-run stop" feature is critical for maintaining sample integrity, as it prevents the counter from registering reverse movements that could skew results. Constructed from a high-performance combination of plastic and titanium, the flow meter offers exceptional durability and corrosion resistance in aquatic environments.

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.
