Sterile Glass Fiber Syringe Filters

Sterile Glass Fiber Syringe Filters

Made from Glass fiber membrane filter and medical pp housing, be ideal for removal of large particulates without clogging. Used as a pre-filter on the first layer of the filter, then conjuration with another membrane. Can be paired with most membranes – but typically with RC, CA, Nylon and PVDF.


Advantage of Sterile Glass Fiber Syringe Filters

Ultrasonic welding ensures no contaminant to samples
Rugged construction to bear autoclave at 121℃ at 1 bar for 20 minutes/EO/Gamma

Features of Sterile Glass Fiber Syringe Filters

Hydrophobic membrane
High flow rate
100% Borosilicate glass
Gamma sterilization

Applications of Sterile Glass Fiber Syringe Filters

Filtration of aqueous & organic solutions
Fast pre-filtration of samples with high particle load
Pre-filter of small volume liquids to avoid saturation of small-porosity membranes

Chemical Compatibility

Incompatible with:
Limited resistance with ammonia, NaOH and KOH solutions
Benzyl alcohol
