Cellulose Syringe Filter FAQ Guide
CA syringe filter is mainly made of cellulose acetate membranes, and it is highly hydrophilic. Since cellulose acetate material has strong strength and low protein binding, CA syringe filter offers various applications, like protein and enzyme filtration, tissue culture media sterilization, biological industry or other places.
MCE syringe filter generally consists of mixed cellulose ester(MCE) membrane, PP/PVC housing and suitable connector. The MCE membrane includes pure and biologically mixtures of cellulose acetate and cellulose nitrate. MCE syringe filter is widely used in aerosol sampling, industrial hygiene, analytical and research applications.
Since both hydrophobic and hydrophilic MCE membrane is available, mixed cellulose ester(MCE) syringe filter is best suitable for both liquids and gases filtration. And MCE filters offers various applications, including food and beverage, air monitoring, venting and degassing, wastewater filtration, microbiological water examination, etc.
Since most cellulose syringe filters are non-sterile, there are various methods to sterilize syringe filters:
- Autoclaving at 121℃ or 134℃ for 15 – 30 minutes
- Gamma radiation
- Dry heat
- Ethvlene oxide
The common pore size of cellulose syringe filter ranges from 0.1 to 8 micron, while bacteria has various micron rating between 0.5 and 5 micron. Theoretically speaking, cellulose can remove most bacteria and 0.2/0.22 micron syringe filter is your premier choice. As for larger and smaller bacteria, customized options will meet your needs.
The designed diameter of cellulose syringe filter ranges form 3mm to 100mm, and more popular diameters are 13mm, 25mm and 33mm. Besides, according to your unique application, customized diameter is also available.
