Cellulose Acetate Membrane Filters

Cellulose acetate membrane filters are a kind of Millipore filtration and play an important role in membrane separation technology. Mainly used for filtration of the aqueous solution.

Features and functions

Cellulose acetate membrane filters with uniform pore size distribution, fast filtration rate, can remove bacteria and particles and no desquamation, which plays a prominent role in sterilization and clarity improvement of injection in the pharmaceutical industry, preparation of high purity water in electronic industry, clinical test, environmental protection, and scientific research.


Cellulose acetate membrane filters are valued because their properties such as thermal stability, chemical stability and strength are better than those of mixed cellulose ester membranes. Compared with mixed cellulose ester microporous membrane, nylon membrane and PVDF membrane, cellulose acetate membrane filters have the lowest adsorption.

Characteristics of cellulose acetate membrane filters

1. Less adhesive;
2. Hydrophilic;
3. High production;
4. Dimensional strength stability;
5. Consistent aperture structure.

Chemical compatibility of cellulose acetate membrane filters is stable in ph4-8, tolerable to most alcohols and oils. The sterilization ways are high-pressure sterilization (121 ℃ or 134 ℃), dry heat sterilization (180 ℃), gamma rays or epoxy ethane fumigation.
