Equipment

Climatostat V3 (TU 26.51.-70-002-63790925-2021)- it has a new unique control unit UB-04T with a touch screen. This climatostat is universal, it combines the advantages of climatostats B2 and P2, and, accordingly, can perform the functions of one and the other. It is intended for performing works on biotesting the toxicity of aquatic environments on daphnia and ceriodaphnia crustaceans, as well as microalgae (scenedesmus, etc.) in controlled environmental conditions. In the climatostat, it is possible to install exposure devices of the type (UER or similar) and to carry out the exposure of samples under conditions of rotation of samples with test organisms in a plane located at an angle to the horizontal. This ensures the intensification of gas exchange of liquid samples with the external environment. A slow rotation ensures complete uniformity of conditions (temperature, lighting, gas exchange) in all samples, including control, and as a result - high reproducibility of the biotest conditions and reproducibility of the test results. The climatostat has an on-board network for connecting additional sample exposure devices, 5 (five) preset modes and 8 (eight) user modes for free programming of the climatostating parameters by the operator. It is intended for carrying out biotesting (according to the methods of Zhmur N.S., "Aquaross" 2001, 2007), Grigorieva Y.S. (SFU)., Terekhova V.A. (MSU, LATAP), hazard assessment of nanomaterials according to the methods of Morgalev Yu.N. (TomSU) and others. Used with test objects: Crustaceans Daphnia Magna (Daphnia magna Straus); Crustaceans Ceriodaphnia affinis (Ceriodaphnia affinis); Crustaceans of salty reservoirs Artemia Salina (Artemia salina L); Algae Scenedesmus (Scenedesmus quadricauda). Algae chlorella (Chlorella vulgaris Beijer), etc. Additional features of the controller (UB-04T): - setting the contrast of information display - sound notification of an open door - audio notification of the end of the biotest - graphical intuitive parameter setting scales - Fully Russian-language menu and Russian-language design of all text information of the interface - 3 (three) preset modes with the exact name and a brief description of the techniques (can be increased or decreased at the request of the Customer) - quick correction of backlight brightness in preset modes (two touches) - fast temperature correction of temperature control in preset modes (two touches) - 8 user modes (the number of modes can be increased or decreased at the request of the customer when ordering) - graphical intuitive scales for adjusting the brightness of lumostating, temperature of thermostating, automatic adjustment of the photoperiod (with one touch) - built-in countdown timers for setting the exposure time in the biotest (up to 180 days with a minimum discreteness of 1 min) - notification of the power failure of the device during the test - error notification - the ability to update the controller firmware directly by the user at the place of operation - quick reset to factory presets
