Description of PTFE Syringe Filter

Disposable PTFE hydrophilic filters made from PTFE Hydrophilic membrane, which are used for many routine preparations in laboratories all over the world. PTFE syringe filters are convenient, disposables for filtration of liquids and removal of particles from solutions and gases. Different from sterile hydrophilic PTFE syringe filters, disposable hydrophilic PTFE syringe filters is a non sterile PTFE syringe filter and easy to use.
Hawach WINSTAR PTFE-L syringe filters with pore size of 0.22μm are golden, and syringe filter with pore size of 0.45μm is pink. Disposable PTFE syringe filter is widely used in biological, chemical, electronics, medical, and other fields.

PTFE syringe structure is precisely designed to ensure smooth filtration, rationalization of internal space and residual rate very low, thereby reducing the waste of samples.

Features of PTFE 0.45 um Filter

•Low residual rate
Nonsterile PTFE syringe filters
•Disposable PTFE hydrophilic filters have two diameter(13mm,25mm)
•0.22μm, 0.45μm pore size can be chosen
•Non sterile PTFE syringe filter
•Color-coded design make easier for identification
•Wide chemical compatibility range
•The color is easy to distinguish, gold color is 0.22μm and pink color is 0.45μm disposable PTFE syringe filter

Advantages of 0.22 um Hydrophilic PTFE Syringe Filters
