OneApplication and characteristics of laboratory positive pressure filter/vacuum negative pressure suction filter

Dongding——Laboratory positive pressure filter/Vacuum negative pressure vacuum filter, with a single-layer or double-layer structure of a disc flat plate, is suitable for microfiltration, particle removal or clarification filtration of small amounts of liquid materials in industries such as biological products, pharmaceuticals, brewing, food and beverage, as well as laboratory filters used in small and pilot scale scientific research. Filter aqueous solutions (culture medium, low protein adsorption, particle analysis microorganisms, solvent mixtures), organic solutions (non-polar), gases, etc.

　　Conditions for use of laboratory positive pressure filters：

(1) Equipped with pressure tanks, peristaltic pumps, compressed air or nitrogen as pressure sources for positive pressure filtration.

(2) Install a vacuum pump or vacuum pipeline for vacuum negative pressure filtration.

　　Application fields of laboratory positive pressure filters：

● Clarification filtration or microporous filtration of various solutions

● Filtration of laboratory solutions and cell culture media

Solid liquid biphasic collection: It can obtain filtered liquid and also collect solid substances in the liquid

　　Sterilization method：Can be sterilized under high temperature and high pressure at 121 ℃ for 30 minutes

IITechnical parameters of laboratory positive pressure filter：

Specifications: DN150, DN200

Flow rate (in water): 80L/h, 150L/h

Filter aperture: 0.22-10 μ m (micrometers)

Filter material: Stainless steel SUS304 or 316L

　　We have made three major improvements to the positive pressure filter in this laboratory:

1. The alignment of the upper body is convenient and accurate, and the filter membrane will not shift or wrinkle.

2. The filtration pressure is 0.3MPa (3bar), and the cross-section of the filter membrane will not leak.
