CLIMATOSTAT FOR BIOTESTING ON VARIOUS TEST ORGANISMS (VARIANTS) Russian patent published in 2022 - IPC C12M1/38 C12M3/00 C12Q1/02 G01N33/18 

FIELD: testing equipment.

SUBSTANCE: invention relates to a device for conducting bioassay of the toxicity of natural, wastewater, aqueous solutions and extracts from samples using small crustaceans, microalgae, small aquatic plants as test organisms, and concerns climatostats. The climatostat contains a heat-insulating chamber, a refrigeration unit, a heater, a light source, a fan and a control unit. As a light source, two LED lamps are used above the shelves with samples. The inner walls of the chamber are made of reflective material, and its transparent door with a built-in heat-insulating double-glazed window has reflective lining. The fans are installed at the top of the chamber and are directed at its back wall, on which the evaporator of the refrigeration unit is mounted, and the heaters are located at the bottom of the chamber. Moreover, electrical connectors for the output of the internal network can be installed on the back wall of the camera opposite each working shelf. Devices for exposing test organisms during biotesting and an algae cultivator for growing these cultures can be connected to them.

EFFECT: improvement of the operational and technical characteristics of the climatostat, the expansion of its functionality is achieved.
