Advantages and Applications of Laboratory Oil-Free Vacuum Pump

The laboratory oil-free vacuum pump is currently a more advanced and widely used vacuum pump product suitable for laboratories in universities, pharmaceutical industry enterprises, agricultural and forestry environmental monitoring units, etc.

Advantages of the laboratory oil-free vacuum pump

Traditional pumps

Customers in traditional fields typically use water circulation pumps or oil pumps with their instruments and equipment. However, water circulation pumps require access to water sources, limiting their use to areas near water tanks, and there is a possibility of backflow in the water tank. Oil pumps require pump oil addition and can generate oil mist pollution, necessitating the use of oil mist filters. Additionally, pump oil needs frequent replacement, and oil pumps generate a certain amount of oil mist pollution during operation. In summary, both of these products require assistance from other media to function properly.

Oil-free vacuum pump

The oil-free vacuum pump does not rely on other media and has a very compact design. Its main feature is completely dry operation, requiring no connection to water sources or addition of pump oil, only needing to be plugged in to work normally. The dry operation allows it to be used anywhere without restrictions, eliminates the hassle of pump oil replacement in the future, and does not generate oil mist pollution, making it suitable for use in rooms with high cleanliness requirements such as cleanrooms. These characteristics make it capable of compensating for some of the shortcomings of traditional vacuum pump products. For example, in a cleanroom environment for aspirating cell culture fluid or filtering culture medium, an oil pump would generate an oil mist, and a water pump cannot be used in cleanrooms without water sources. An oil-free laboratory vacuum pump does not have these inconveniences.

Applications Introduction

Based on the above characteristics, the oil-free laboratory vacuum pump is very suitable for the following applications or can be used with the following instruments:

  • Various liquid suction in laboratories: Including suction of waste liquid from culture media, supernatant from centrifuge tubes, and residual liquid from other experiments. These applications must absolutely avoid pump oil or water backflow. Suction of waste liquid from culture media is especially important in cleanroom operations, requiring a pollution-free product, making a liquid suction pump designed with an oil-free principle the best choice.
  • Vacuum drying chambers (or small vacuum dryers): Small vacuum dryers generally have a small volume and are used for dehydration and drying operations. They can be used with oil-free vacuum pumps.
  • Vacuum filtration (pressure filtration): Vacuum filtration requires creating a vacuum inside the filtration bottle to form a pressure difference inside and outside, pushing the filtrate through the filter membrane. Generally, vacuum filtration does not require high pumping speed or vacuum level, making oil-free vacuum pumps suitable.
  • Used as an air source with other instruments and equipment: This type of application is more diverse, and because it needs to be used with other equipment, using an oil pump or water pump may affect the supporting equipment. It is generally recommended to use oil-free vacuum pumps for support.
