Microporous MEMBRANE FILTER

Products Introduction

In the applications of membrane separation technology , microporous membrane filter is the most widely application and easy to use . High flow rate , high particle entrapment rate , good temperature resistance , resistance to strong acid , strong alkali , organic solvents and antioxidant , ageing resistance and not sticky , incombustible , and non-toxic , good biocompatibility , etc . It’s material divided into two categories : organic and inorganic , as the separation characteristics of microporous membrane filter , it is mainly used for retaining from gas phase and liquid phase particles , bacteria and other pollutants , in order to achieve the purpose of purification , separation and enrichment . For microfiltration membrane intercept features based on the pore size of the membrane , usually in 0.1-1μm , so the microfiltration membrane can seprate the large diameter of the bacteria , suspended solid and so on . It can be used as general material liquid clarification , security filters , air aseptic , widely used in scientific research , medical science , biochemistry , food , energy , microelictronics industry , nano technology , environmental protection and other departments .

Applications

  The product is mainly used in mobile phase of chromatographic analysis and sample filter , to protect the chromatographic column and infusion pump pipe system and the sampling valve is not contaminated . Widely used in gravimetric analysis , trace analysis , colloid separation and sterility test . According to the filter samples to choose the appropriate membrane filter .

New product ---PM2.5 Special Membrane Filter

PM2.5 special membrane filters are produced in 100,000 purification workshop , high toughness , high sensitivity , interference-free , low impurity , etc ., it’s the best choice for airborne particulate sampling and analysis . In addition , PM2.5 special membrane selection of PTFE material , is one of the most inert material , with a wide range of chemical compatibility , can tolerate a wide range of acids , bases and polar solvents , can filter the corrosive chemicals subject . And has a very low of non-specific adsorption properties and almost zero extract .

Application:

1.PM10,PM2.5 Lane sampling and other techniques for air sampling and testing
2.Low ash for high –precision gravimetric determination 

3.Resistance to chemical corrosion , for corrosive environmental sampling , and the corrosive chemicals that normal membrane filter can’t do
