Description of PTFE Syringe Filters

If the sample contains a lot of particles or viscous impurities, 0.45um syringe filter with a pre-filter membrane is your ideal choice. The pre-filtration membrane filter adds a layer of pre-filtration membrane before the membrane of the ordinary syringe filter to protect the microporous membrane. The material is 1um Glass Fiber or PP.

The pre-filtration membrane can remove particulate impurities while preventing sticky impurities from clogging the filter. The pre-filter membrane is made of chemically inert materials and is resistant to most solvents. The rigidity of the membrane and the structure of large specific surface area have the characteristics of small retention capacity and low resistance, so the pre-filtration membrane filter can maintain high flux even when processing difficult-to-filter samples. IC syringe filters are common to both aqueous and organic solvents. Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic contaminants be introduced in sample pretreatment. Like sterile CA syringe filters, hydrophilic PTFE syringe filter can be used in HPLC analysis and IC analysis to filter sample solutions, which is a sample pretreatment process important step in the process.

Just like the hydrophobic PTFE syringe filter, the hydrophilic PTFE syringe filter also has a high flow rate, filtration accuracy as well as great resistance to chemicals and high temperature. Nevertheless, it possesses strong and permanent hydrophilicity without the need for pre-wetting. PTFE 0.45 um filter could be widely applied in the pharmaceutical industry for sterile filtration of various water-soluble solvents, including eye drops and antibiotics. Meanwhile, 0.45um syringe filter is also perfect for the sterile filtration of highly corrosive solvents and organic solvents.
