Sterile Hydrophilic PTFE Syringe Filters

Hawach sterile hydrophilic PTFE syringe filter autoclave at 121°C at 1 bar for 20 minutes/EO/Gamma. Each PTFE filters is individually packaged and suitable for high sterilization requirements.
Sterile filter is a kind of filter connected to the front end of the syringe. 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. Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic pollutants be introduced in sample pretreatment.

The hydrophilic PTFE syringe filter can instead of PES, N6, PVDF syringe filter, is used for high temperature liquid filtration with excellent biological safety, chemical inertness, low adsorption and high temperature resistance. The pore diameter is 0.22μm/0.45μm, the flux is large, the strength is high, and the high temperature does not fall off. The syringe filter 0.22μm is suitable for the filtration of strong acid and strong alkaline solutions, the terminal sterilization filtration of liquid medicine, the filtration of high temperature liquids, the environment where water treatment and other filter materials are not competent.

Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic contaminants be introduced in sample pretreatment. These 0.22/0.45 um PTFE syringe filters can be used in HPLC analysis and IC analysis. Filtering sample solutions is an important step in the sample pretreatment process.
