Abstract
A device for biological evaluation of toxicity of water contains a vessel for water to be tested and test-organisms, which upper part is made in the form of a truncated cone which minor base is turned upward, a counting chamber fastened to the upper part of the vessel, and a valve. For the purpose of enhancement of rapidity and accuracy of evaluation of water toxicity the device is additionally supplemented with a glareshield covering the vessel, and a light source for attraction of living test-organisms, a power supply and a switch. A bottom of the vessel is made movable in the form of a piston and contains the light source. The valve is located on the free end of the counting chamber for removal of air excess at the piston displacement. Between the counting chamber and the valve a diaphragm is mounted preventing exit of test-organisms from the counting chamber.
