Just in time to make your hours in the lab more productive. Let statistics - and the accuracy of our grid - do the counting. There’s no need to count what’s in the entire cell; extrapolate the number of “critters” in a portion of the cell. Contains a 1 x 3” glass slide mounted on a brass frame and meticulously drawn with a millimeter square grid in a chrome-on-glass procedure. Cell is 50 mm x 20 mm x 1 mm with a volume of 1.0 mL. Lines of grid are .0007” (0.18mm) wide. There is one microliter of water per gridded square of the cell.
Specifications: • Frame: brass, mounted on 1" x 3" glass slide. • Cell size: 50 mm x 20 mm x 1 mm (1.968" x 0.787" x 0.04") • Cell volume: 1.0 mL • Includes: 2 cover glasses. • SR-02 : Gridded model includes 1mm x 1mm grid etched on slide with 1 microliter of fluid per gridded square.

Manifolds Vacuum Holder is particular design and produce for several samples filtrate at the same time. At present domestic laboratory filtrate liquor usually adopt the glass nature core, while this method only filtrate one sample once, and it has low speed, low efficiency, and much labor exertion. It is more convenience for the operator who needs to filtrate several samples at the same time. Because each filter holder have individual control valve, only one set vacuum pump can sustain the single or Manifolds Vacuum Holder operate together. While stainless steel nature of the Manifolds Vacuum Holder can filtrate at 180 temperature ;and the high-quality extra hard glass is elegant in workmanship, and be able to bear up 200 range of temperature. The clamp of aluminum alloy designed rational and closed, it can make the filter bowl together with the middle filter head become an organic, and assure them airproof not to leak. Simultaneity, type 316L stainless steel resistant to acids alkalis,and be able to bear corrosion, easy to high-temperature sterilization. Therefore, it makes the analyze result much more stabilization and trustiness.
The Bottom Sediment Grab Sampler is a kind of laboratory equipment, which is used for collect the mud( sediment/sludge/deposit) samples from the bottom of rivers,lakes,ponds,shallow sea etc.
Net is made by nylon for durability and accuracy of mesh size. The 8“ diameter net mouth is braced open by stainless steel ring and bridle, mesh length 24” . Plankton Net with 80 µ m Mesh Net Include bottle adaptor with 250 ml sample bottle
Nets feature a small net ring and a 15” net. Net is made by nylon for durability and accuracy of mesh size. The 5 “ diameter net mouth is braced open by stainless steel ring and bridle. Plankton Net with 80 µ m Mesh Net Include bottle adaptor with 125 ml sample bottle
Test kit screens for coliform bacterial contamination
Store at room temperature—no incubator needed
Simply pour sample into bag, shake to dissolve dechlorinating tablet, pour into the five glass tubes, and store tubes at room temperature. Color change and small bubble formation provide indication of bacterial presence. What's included: sterile water sampling bag with dechlorinating tablet, five 10-mL glass tubes, and five coliform test tablets.
Color titration method determines dissolved oxygen levels
Winkler titration method to test samples or calibrate meters
Inexpensive backup in case of meter failure
This test is an azide modification of the Winkler method where oxygen, in the presence of a strong alkali, oxidizes manganese, which in turn reacts with iodide to form iodine. This is titrated with a standard thiosulfate solution in the presence of a starch indicator to enhance the endpoint. Azide eliminates the nitrite interference. Test kit and refills contain enough reagents for 50 tests at an oxygen level of 10 ppm.
Determine water flow in closed circuits or open channelsBiodegradable and nontoxic
Dyes diffuse rapidly in water, producing a vivid, easy-to-see color. Excellent for identifying diffusion and dispersion patterns, rates of flow, di scharge locations, seepage areas, sea marking, and more. Fluorescent yellow/green dye (fluorescein) works best in silt-filled waters. Use an ultraviolet lamp (order separately below) to trace fluorescent red or yellow/green dyes where normal visual detection is difficult. Minimum detectable concentration of all dyes in clear water is 1 ppm.
