 There are many models of Vacuum drying ovens, but the basic structure is similar, generally consisting of three parts: the Vacuum drying oven, electric heating system, and automatic temperature control system. Connect the vacuum pump with the vacuum valve, open the vacuum pump and the vacuum valve in turn, and pump the vacuum. Caution. ①According to the performance of the vacuum pump, the pressure gauge shall be the limit value of the vacuum pump. When the vacuum degree is reached, close the vacuum valve first (if the vacuum valve is not tightly closed, it needs to be replaced in time), and then turn on the power of the vacuum pump. (a) Closure or removal (to prevent back drafting). ③ Observe the vacuum pressure gauge to ensure that the value is stable without significant fluctuations. ④If the vacuum degree is lower than the requirement of dry goods, open the vacuum pump power and vacuum valve again and continue to evacuate. Vacuum pump lifetime. The vacuum drying oven KZ series can

Recently, some customers are asking how to ensure that the vacuum drying oven does not leak after several years. In fact, when the vacuum drying oven leaks after several years of use: Possible causes: When used for a long time, there is air leakage. The biggest possibility is not that the drying oven is broken, but that the sealing parts are damaged and aged. Solutions: Only need to replace the sealing strip, if you still can't solve the problem, that is the valve is damaged, replace some valves. How to ensure that the vacuum drying oven does not leak after several years? Buyers can buy products made by some brand manufacturers. The silicone door seal is formed as a whole to ensure that it will not break due to interface problems after a long time of use. vacuum drying oven

Environmental chamber with  many users put in samples due to the result of the experiment is not the standard operation is not accurate, its applicable temperature experiment box up and down to stop the experiment time put on the sample, there is a clear rule under the  Environmental chamber  manufacturer Kenton instrument is summary about how to correctly put sample time for you! 1, liquid test products in the  Environmental chamber  must be filled with the corresponding container, and it is best not to exceed 2/3 of the container, to avoid liquid overflow. 2, chamber   volatile, flammable, and explosive items to stop putting into the experimental box to stop the experiment, conventional equipment has no explosion-proof function. If we must stop such experiments, we must indicate with consumer manufacturers before ordering equipment and request consumer manufacturers to stop some special corrections to the equipment, such as explosion-proof, etc. 3. Rubber experimental products in th

The Control system is the core of the constant temperature and humidity chamber , it determines the temperature rise rate of the text chamber, precision, and other important indicators. Now the controller of the test chamber mostly adopts PID control, but also a few adopts PID and fuzzy control phase combination control mode. Because the control system of the thermostatic oscillator basically belongs to the category of software, and this part in the use of the process, generally there will be no problems. In the constant temperature and humidity chamber refrigeration principle diagram, we introduced the temperature and humidity chamber refrigeration system several important components of the working path. So how do these components work? The refrigerant is adiabatically compressed to a higher pressure by the compressor, and the work is consumed to raise the exhaust temperature. After that, the refrigerant isothermally exchanges heat with the surrounding medium through the refrigerant c

The differences between the Laminar flow cabinet and biosafety cabinet are mainly as follows: 1, biosafety cabinet is safety equipment widely used in scientific research, teaching, clinical testing, and production in the fields of microbiology, biomedicine, gene recombination, animal experiments, biological products, and so on. It is also the most basic safety protection equipment in the first-class protective barrier of laboratory biosafety. 2, Laminar flow cabinet , designed to protect experimental materials, the air is sucked into the pre-filter through the fan, and filtered into the HEPA filter through the hydrostatic chamber, and the filtered air is sent out in the state of vertical or horizontal airflow, so that the operating area can reach the cleanliness of 100, to ensure the production of environmental cleanliness requirements. Can only protect the sample, not the operator. 3, the biological safety cabinet is a negative pressure purification table, the correct operation of th

The light incubator is an upgraded version of the biochemical incubator, with constant temperature functions such as heating and cooling, while adding a controllable light function, simulating the change of illumination at different times of the day and night, using different light intensity, light quality, light-darkness ratio, with temperature and humidity changes to observe the growth of products, is the main equipment for environmental testing in biology, medicine, agriculture and animal husbandry, forestry, environmental science, aquaculture, and other departments. The main equipment, widely used in plant seedling selection and cultivation, monitoring the culture of algae in water bodies, water analysis BOD determination, insect and small animal feeding, cell proliferation preservation, and other tests, can also be used for drug stability tests.
