Laboratory oil-free vacuum pump have? - - - - - -

vacuum pump application is more and more widely in the laboratory. Vacuum pump can be used together with other instruments, rather than a single device. In the lab, different types of imported vacuum pump for manufacturing various chemicals and dealing with dangerous substances and volatile liquid is necessary. What import vacuum pumps suitable for laboratory use? In the use of vacuum pump after a period of time, many users will encounter all sorts of problems, such as lack of the vacuum degree of vacuum gauge observed ( Inadequate suction) , pumping speed too slow, in a relatively closed when there's so much noise in the room, or the use of the pump oil mist can't normal use, etc. The problem is often associated with type selection. In order to solve this problem, the following solutions are given.

import vacuum pump is a volatile liquid from one place to another place ideal choice, because it is completely closed, can without damage to the system of handling items. Vacuum pump can also be quickly and efficiently mix various types of viscous liquid. However, not all laboratory vacuum pumps are the same. Vacuum pump is an essential part of every laboratory auxiliary equipment, the application of different instruments and equipment need different vacuum pump.

buy laboratory vacuum pumps, mainly consider the following factors:

1. Need to protect the environment from pollution?

due to the design principle, some imported vacuum pump to assist the operation of the pump, you need to use other media such as oil rotary vane vacuum pumps and water circulating pump, they need to oil injection pump and connecting water respectively. When using the oil pump, oil mist emissions into the air, pollute the environment; Pumps must be located on the edge of the sink, because it needs to connect to the water. However, some need to pump in cell room clean room on cell culture supernatant of customer cannot use this product. At this point, should choose oil-free vacuum pump, such products can be plugged into a power supply.

2。 What kind of instrument and equipment used together

the purpose of using different equipment and different. Some requirements of high vacuum degree, such as vacuum distillation. Some have higher request for extraction speed, such as vacuum drying oven, need to consider the case of internal volume. However, the application of the vacuum filter is more complex. It is necessary to check the capacity of filtrate and liquid particles content, and then according to the different situation to choose the appropriate products or vacuum pump speed.

3。 The volume of matching equipment

the volume of equipment and pumping speed of vacuum pump on the correlation between parameters. It is necessary to choose for different size of the filter pump speed higher suction pump matching.

what import vacuum pumps suitable for laboratory use?

there are actually three different types of laboratory vacuum is considered to be the ideal:

1. Chemical pump

chemical pump has a special material to protect them from chemical exposure. Materials used in the pump is non-corrosive, will not burst by repeated chemical exposure. In dealing with a large number of chemical liquid and this material is very useful in industry.

2。 Oil-free vacuum pump

it is intended to provide the cleanest way to travel. Vacuum operation without any kind of oil lubrication, which makes them very suitable for transportation of fine materials and the existing liquid oil, it may become contaminated. No oil pump can run in a different form, also saves the need for additional external lubrication of the cleaning operation.

3。 High vacuum

high vacuum water pump, pump with high strength, quick inhalation of liquid viscosity. It is the laboratory clean and various laboratory liquid to move quickly from one place to another place of ideal high vacuum pump. For the transportation need to keep stable temperature or mixture liquid is ideal.
