cryo rack
Some customers who need to cryo rack the cell culture supernatant in the clean room of the cell room cannot use this type of product. Whether the use environment needs to ensure that there is no pollution: part Due to the design principles of vacuum pumps, other media are required to assist the operation of the pump, such as oil rotary vane vacuum pumps and water circulation vacuum pumps, which need to pour pump oil and connect water respectively. For example, the vacuum control valve has a very important role for many purposes.How to choose the vacuum pump used in the laboratory is a problem that plagues many users. For example, when matching with a 2000-5000ml filter bottle or a triple filter, you can choose R400, with a pumping speed of 34L/Min; 5L-10L A filter bottle or a six-line filter requires R600 with a pumping speed of 60L/Min or more.
When the pump oil is in use, the oil mist will be emitted into the air, polluting the environment; and the pump must be connected to the water source at the side of the sink. At this time, you should choose an oil-free vacuum pump, which can be used after plugging in. 2. 3. However, when a large-volume vacuum filter bottle or multiple filter is used, such as a filter bottle of 5000ml or more, a triple filter, and a six filter, the filtration speed will be greatly reduced.
It is a very useful accessory, such as BS-02250 water blocking filter with built-in drain With a high-performance filter membrane, air can pass, but 100% liquid cannot pass, which can completely solve the problem of suction. It can be used as long as it has an ordinary 220V power supply. Can meet the needs. When purchasing a vacuum pump, you should pay attention to directly configure the necessary accessories according to different applications. The volume of the matching equipment:
The volume of the equipment is related to the pumping speed parameters of the vacuum pump. It is necessary to investigate the filtrate capacity of the filtration, the content of particulate matter in the liquid, and then choose the appropriate vacuum or pumping speed product according to different situations. The general user may not be able to figure out the relationship between the various parameters of the vacuum pump and the actual use effect. When performing vacuum filtration, the anti-suction accessories set, including buffer bottles and water blocking filters, will effectively avoid the problem of suction damage to the vacuum pump. 4
