Sterile filtration is used in many applications: serum-containing or non-serum-containing media that supports the growth of cell cultures, reagents or solutions containing sensitive components that will degrade during high temperature processing, and when there is no autoclave, filtration should be added to the sterile growth media supplement Liquid, filter samples to avoid microbial growth during storage, filter buffers, remove particulate matter and avoid microbial growth during storage, filter biological samples to be analyzed, avoid microbial contamination of expensive equipment, filter environmental samples to be analyzed, filter fermentation liquids, Further purification or analysis.

The hydrophobic PTFE membrane has extensive chemical compatibility and very low dissolution, and is currently the most chemically resistant membrane among all filter membranes. Aijiren’s innovative design allows the PTFE filter to achieve a perfect balance between the increase in effective filtration area and the decrease in sample retention volume. The filter can withstand higher operating pressures, effectively avoiding leakage.

PTFE Syringe Filter is resistant to almost all corrosive chemicals, which makes PTFE syringe filters an ideal choice. However, the disadvantage of natural hydrophobic PTFE is that after many chemicals are diluted with water, the aqueous solution cannot pass through. Need to be wetted with water in advance.

Syringe filter is a disposable filter unit designed to remove impurities from liquids or gases using a syringe as the fluid delivery system.
It consists of a plastic housing with an inlet and an outlet, and a filter membrane positioned between them.
The filter membrane is often made of materials such as polypropylene, polytetrafluoroethylene (PTFE), or nylon.
To use a syringe filter, the liquid or gas to be filtered is drawn into a syringe, and then the syringe is attached to the inlet of the syringe filter.
