Sterile GF (Glass Fiber) Syringe Filters

Hawach sterile GF syringe filters autoclave at 121°C at 1 bar for 20 minutes/EO/Gamma. Each syringe filter is individually packaged and suitable for high sterilization requirements. These filters are widely used in biological, medical and other fields.
The glass fiber syringe filter is a natural hydrophobic filter medium, which has the characteristics of large flux and large dirt holding capacity. It is suitable for the regular filtration of organic solvents such as high particle content, strong alkalinity, and viscosity. In HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. Therefore, samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument.

The sterile syringe filters are widely used in laboratories. This syringe filter can use for cell culture. They do not require membrane replacement and filter cleaning, eliminating complicated and time-consuming preparations. Difference from sterile cellulose acetate syringe filters suitable for protein recovery, glass fiber syringe filter suit for hplc analysis.

Advantages of Sterile Glass Fiber Syringe Filters

•High flow rate
•Hydrophobic membrane
•Good mechanical strength
•Good pre-filter to extend membrane life

Applications of Sterile GF Syringe Filters

Syringe filter for cell culture
