What kind of rotary vane vacuum pump is very suitable for the application in the laboratory

how to choose vacuum pump used in the laboratory for the user is a problem. After buying vacuum pump, many users will encounter vacuum gauge, vacuum found enough ( Inadequate suction) , pumping speed too slow, and used in relatively closed room. Pump will appear all sorts of problems, such as too much noise or oil mist, can't normal use. The problem is often associated with choice. Rotary-vane vacuum pump are usually used in the laboratory. With stable performance, durable, powerful advantages. No oil mist exhaust, low noise, small vibration. Therefore, rotary vane vacuum pump is very suitable for the application in the laboratory.

the average user may not be able to understand the import of the rotary-vane vacuum pump parameters and the relationship between the actual use effect. In general, the user to buy laboratory vacuum time mainly consider the following factors:

1. Should use the environment pollution-free, due to the design principle, some vacuum pump to assist the operation of the pump, you need to use other media such as oil rotary vane vacuum pump and vacuum pump water circulation, they need to pour into oil and connect to the water pump. When using the oil pump, oil mist will send out may pollute the air environment, must use connect the pump to the position of water next to the sink. Need some suction in the room, clean room of cells on cell culture supernatant of the customer can't use such products. At this point, they should choose oil-free vacuum pump, plug the power supply after use.

2。 What kind of instrument and equipment used together: different devices with different purposes, some require higher vacuum degree, such as vacuum distillation; Some require higher pumping speed, the vacuum drying oven, for example, to consider. The inside of the box volume; And the application of vacuum filter is much more complicated. Must check the filtered particles content in the capacity of filtrate and liquid, and then according to the different situation to choose the appropriate vacuum degree or suction speed.

3。 The volume of the volume of equipment: equipment related to the pumping speed of vacuum pump parameters. For example, when using general 1000 ml vacuum filter bottle, I only need to use the minimum vacuum pump pumping speed of 20 l/min. Suitable for their own needs.

4。 To ensure the normal use of the attachment is what: during the use of certain vacuum system lack of accessories may make the operation very difficult. For example, vacuum regulator plays a very important role in many ways. You can observes the working state of the system, and according to the actual need to adjust the pumping speed. In the process of vacuum filter, including buffer bottle and block water filters, the defence of the suction fittings group can effectively avoid the damage to the vacuum pump absorption problems, are very useful accessories.

laboratory vacuum pump has a very wide range of USES. Rotary vane vacuum pump application in the laboratory mainly includes the following aspects:

1) Vacuum filter: can be used with various laboratory vacuum filtration equipment, such as solvent filters, sand core filter bottle, buchner funnel filter bottle, bottle cap filters, microbial limit test filter equipment, multigang filters, etc. Laboratory vacuum pump of high vacuum degree and pumping speed, so especially suitable for large capacity filter bottle and has a large number of channels of multigang filter. Under the dynamic condition, such as water or filtering suspended solid or high solid content in the samples, using laboratory vacuum pumps can obtain excellent results;

2) Vacuum drying: suitable for use with small vacuum drying oven or vacuum drying oven. Laboratory of vacuum pump used to eliminate the need for replacement pump oil, save unnecessary trouble, and reduce the noise.
