0.45μm Pore Size PTFE Syringe Filters Hydrophobic for Lab Filtration
Syringe filters offer easy-handling microfiltration for HPLC sample preparation and other life science laboratory filtration applications such as filtration of cell and tissue culture media etc. Polytetra fluoroethylene PTFE Syringe Filters from us consist of premium PTFE membranes and high quality PP housing. These syringe filters are highly recommended for HPLC and GC sample prefiltering, gas filtration, sterile venting and sterilization and clarification of most solvents.
Key features of PTFE Syringe Filters
The PTFE membranes of the syringe filters are manufactured by ourselves in our 100,000 grade cleanrooms, and the housing production and product- assembly are done in our own automatic injection-molding facilites. This makes us stand out from other manufacturers who have to purchase the membranes and shells to complete the assembly, and makes us more flexible and competitive on pricing. And we offer free sample service, contact us and you'll get desirable products at amazing price!
Specifications
PTFE syringe filters from us are available in two pore sizes – 0.22 and 0.45µm, and different diameters – 13, 25,30mm (33mm).

Applications
The PTFE Syringe filters from us are available in sterile and non-sterile packs, sterile syringe filters are typically used in life science applications while non-sterile syringe filters are utilized in analytical chemistry including for filtration, sample preparation and contaminant particle removing.
• Sterilization (0.22 μm) and clarification (0.45 μm) of most acids and aggressive solvents
• Filtration and degassing of solvents prior to analysis (0.45 µm)
• Venting of sterile containers (0.22 µm)
• Sterilization of air, gas and aerosol (0.22 µm)
• Tool for protection within vacuum pump (0.22 µm)
• Clarification of small volume samples for HPLC and GC applications, which require greater chemical resistance than other types of syringes filters (0.45 µm)
• Clarification and sterilisation of organic solutions
