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.

Displaying the spectra and dose rates measured by each detection unit (DB) on the object plan or terrain map Identification of the radionuclide composition of the source The possibility of expanding the energy range up to 5 MeV Sealed DB design (IP68) Backup power supply

The spectrometer was created according to the Cherni-Turner scheme based on a flat diffraction grating and an MAES analyzer with one line of photodetectors. It has increased photometric accuracy due to cooling and temperature stabilization of the photodetector range, as well as due to its shell-less design, in which there is no re-reflection of radiation on the cover glass and the background level in the recorded spectrum decreases. The optical scheme and design of the spectrometer are optimized to obtain a high-quality spectrum with a low level of background radiation in any of the regions lying in the spectral range of 190-1100 nm. The choice of the working area is carried out by changing and rotating the diffraction gratings. The sealed case of the spectrometer is filled with an inert gas. The radiation is injected into the spectrometer using a quartz capacitor or a fiber-optic cable with an SMA-905 connector. The optical scheme and design of the spectrometer are protected by patents.

The working condition of the ND-630 diffusion pump depends on the temperature of the working fluid in the pump boiler. During the initial filling, it is recommended to fill the maximum volume of the working fluid. Working fluid is "VACMA OIL 500" vacuum oil (uner technical specifications TU 19.20.29-061-00218526-2019). The total amount of working fluid in the ND-630 diffusion pump is a maximum of 9 liters, a minimum of 6 liters. The viewing window for visual inspection of the working fluid has marks of its maximum and minimum amounts. During normal operation of the pump, the level of the working fluid practically does not change. The temperature of the working fluid when the pump is operating at the maximum residual pressure is about 240°C to 255°C. It is recommended to monitor the operation of heaters in the ND-630 diffusion pump using one temperature sensor. The temperature sensor must be installed in a special radiator socket above the heater. If there is a loss of working fluid and an increase in the temperature of the radiators of the ND-630 diffusion pump up to 360°C, the temperature sensor must give the command to automatically turn off the heaters. The subsequent activation of the pump heaters should not be automatic and should be performed only after cooling the system. Water at the inlet to the cooling systems of the housing and the oil reflector must be supplied with a pressure of 0.3 MPa (3 kgf/cm2) to 0.5 MPa (5 kgf/cm2) and a temperature of plus 4°C to plus 25°C. The recommended cooling water consumption for the housing is 600 l/h, for the oil reflector it is 80 l / h. It is regulated by the outlet water temperature, which should not exceed plus 40°C. The water drain should be free (with a jet break).

It is intended for thermostating samples in glasses, flasks and other laboratory utensils in cases where high accuracy of temperature maintenance is not required and good uniformity of the temperature field in the working volume is not needed. The operating temperature range is Current +5...+200 °C. One workplace with a diameter of 110 mm with five steel O-rings. Stamped steel bath with a volume of 3.5 liters and a depth of 100 mm.
