Laboratory mute oil-free vacuum pump is more and more widely used. Vacuum pump can be used together with other instruments, not a single device. In the laboratory, different types of imported vacuum pumps are necessary for creating various chemicals and handling dangerous substances and volatile liquids. Which imported vacuum pumps are suitable for laboratory use? After using the vacuum pump for a period of time, many users will encounter various problems, such as insufficient vacuum degree observed by the vacuum meter (insufficient suction), too slow pumping speed, too much noise when using in a relatively closed room, or the pump has oil mist and cannot be used normally, and these problems are often related to the type selection.
Mute oil-free vacuum pump is an ideal choice for conveying volatile liquids from one place to another, because it is completely enclosed and can handle items without damaging the system. Vacuum pumps can also quickly and effectively transfer many different types of viscous liquids. However, not all laboratory vacuum pumps are the same. Vacuum pump is an indispensable auxiliary equipment in every laboratory, and the requirements of vacuum pump are different for the application of different instruments and equipment.
The following factors are mainly considered when purchasing laboratory vacuum pumps:
Whether the use environment needs to ensure no pollution
Due to the design principle, some imported vacuum pumps need to use other media to assist the operation of the pump, such as oil rotary vane vacuum pump and water circulating vacuum pump, which need to pour pump oil and connect water source respectively. When the pump oil is in use, the oil mist will be emitted into the air and pollute the environment; Because the water pump needs to be connected to the water source, the place of use must be beside the water tank. Some customers who need to pump the supernatant of cell culture in the clean room of the cell room cannot use this kind of product. At this time, they should choose an oil-free vacuum pump, and this kind of product can be used when plugged in.
What kind of instruments and equipment are used together
Different equipments are used for different purposes. Some require higher vacuum, such as vacuum distillation; Some require higher pumping speed, such as vacuum drying oven, which needs to consider the internal volume of the box; The application of vacuum suction filtration is more complex. It is necessary to check the filtrate capacity and the content of particles in the liquid, and then select the appropriate vacuum degree or pumping speed products according to different conditions.
Silent oil-free vacuum pump
There are actually three different types of ideal laboratory vacuum:
Chemical vacuum pumps are made of special materials to protect them from chemical contact. The materials used in the pump are non corrosive and will not be broken through repeated chemical contact. It is very useful in the industry dealing with large quantities of chemical liquids and materials.
Silent oil-free vacuum pump
It aims to provide a clean means of transportation. Vacuum operation does not have any type of oil lubrication, which makes them very suitable for transporting delicate materials and the presence of liquid oil, which can become pollution. Oil free pumps can also use different forms of operation, negating the external lubrication that requires additional cleaning operations.
High vacuum pump, with high strength, can quickly absorb a variety of liquids with different viscosities. It is an ideal high vacuum pump for laboratory cleaning and rapid transfer of various laboratory liquids from one place to another. It is particularly ideal for transporting liquids that require maintaining a stable temperature or mixture.
