Bogorov Counting Chamber, Disposable, Acrylic x 2 u.

$ 46.12 USD

The original classic device is the perfect size to hold a small volume of sample - about 6 ml. The shape and configuration of the shallow, etched groove (1/8" deep and 3/16" thick) help locate specific areas on the chamber.

With guidance from John Gannon of the Great Lakes Lab in Windsor, Ontario, Wildlife Supply (TM) has developed the definitive low-cost apparatus for enumerating zooplankton micro-crustacea. The modified device is the perfect size to hold a large volume of sample - about 39 ml, in fact. The shape and configuration of the shallow, also etched groove (1/2" deep and 3/8" thick) help locate specific areas on the chamber.

A compact 3-1/2" by 4-1/2" in size, it slips easily under a dissecting microscope. Straight sides mean you don't have to focus up and down. Rounded edges prevent specimens from catching.

Combined Plate Chamber (Utermöhl-Chamber) Hydro-Bios

$ 1,155.00 USD

⚠️ Do NOT use alcohol for cleaning acrylic parts.

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.

Fieldmaster Student Limnological Secchi Disc

$ 30.00 USD

Need to determine how clear the water is? Measure the turbidity or degree of visibility of the water you’re testing with the limnological secchi disc. Results are meaningless if they’re not repeatable and can’t be compared.

The sturdy plastic Secchi disc handily meets industry standards. It is 200 mm in diameter (7-7/8”) and has four quadrants, two white and two black. It is included 20 meters of 1/8” diameter line on a styrofoam form that will float if dropped in the water. Plus instructions that are written at a basic level.

Most scientists use a Secchi disc to determine the index of suspended matter in the water. The smaller the index - say, five feet - the more suspended material there is. The water is, obviously, less transparent, with a lower degree of visibility.

You can also use a Secchi disc to measure the depth of light penetration and can derive a rough estimate of the extent of the littoral zone.

Please note that this unit is designed for occasional student use only and is not meant to replace the professional Secchi discs.

Heron Water Level Meters Dipper-T

$ 852.00 USD

Four Function Water Level Meter

The dipper-T water level meter is designed for well drillers, consultants and hydrogeologists all across the globe. The dipper-T is manufactured for professionals who require the most accurate measurements of water levels, length of well-casing and total well-depth.

The Heron dipper-T is renowned for its premium, polyethylene coated yellow steel tape accuracy in measuring depth to water. Available in your choice of either metric or engineering scale.

The dipper-T water level meter can be conveniently converted to a multi-functional instrument, not only able to measure static and falling head levels, but also to determine the length of casing and well depth. The water level sensing probe can be easily removed at the link connection and substituted with either the Well Casing Indicator Probe or Well Depth Indicator Probe. The FOUR FUNCTION capability of the dipper-T water level meter makes this unit an asset to groundwater professionals and rural property owners during the construction of new wells, maintaining wells or decommissioning abandoned wells.

Static mode is used for measuring the depth of water in wells, boreholes and standpipes. DrawDown mode is used for measuring falling water levels during purging, well development and for low flow sampling.

The Well Casing Indicator Probe (Sold separately) is used to measure the depth of metal casing in wells and boreholes from two inches in diameter and upward. The Well Casing Indicator Probe works using magnetism. While the probe sits within the magnetic field of the steel casing, an auditory and visual signal is active. When the probe leaves the magnetic field the signal stops. Note the condition of the well for accurate readings. Recommended Use: New Construction Only (Old/Imperfect casing may cause false or inaccurate readings when using this probe).

The Well Depth Indicator Probe (or bottom detector; Sold separately) is used to measure the full depth in wells and boreholes. The Well Depth Indicator Probe uses a pressure sensitive plunger to measure the distance to the bottom of the well. When the Well Depth Indicator Probe reaches the bottom of the well, the plunger enters the probe body closing a switch, initiating an audible and visual signal at the top of the well.

It is the User's responsibility to ensure chemical, temperature, radiative, and shock compatibility with their site(s) before, during and after deployments. Not doing so will void any and all warranties.

Heron Water Level Meters Water Tape

$ 715.00 USD

Static & drawDown Levels

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.

ICES Incubator Hydro-Bios

$ 5,035.00 USD

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.

Supplied with a standard calibration curve (number of counts/unit time vs. velocity) sealed inside transparent body. A single pin and lanyard system located ahead of the lateral center of mass allows the flowmeter to maintain correct dynamic alignment with the fluid flow in which it is immersed. The ref. 2030R6 with a rotor of 7 in, is ideal for slow water (6 to 100 cm/sec) and ref. 2030R with a rotor of 3 in, is ideal for faster water (10 to 790 cm/sec).

Available extension handle for use of mechanical flowmeters in streams and moving water. 8 feet extends up to measure the flow of current hard to reach.
