Sterile, Glass Fiber Prefilter (GF) Syringe Filters

Can be used as preliminary filtering step and for solution clarification without clogging. Extends membrane life when filtering viscous solutions. Filters are made of 100% binder-free borosilicate glass fiber and are an excellent choice for solution purification.

•  Sterile, Individually Wrapped.
•  Glass Filber is 1.1um pore size.
•  Use in tandem with other 30mm size syringe filters, Luer locks for easy use.
•  RNase/DNase/Pyrogen Free.

Applications for Sterile Syringe Filters with Glass Fiber Prefilter:
• Prefilters for highly viscous solutions, particulate removal, difficult to filter samples.

NOTE:  These Prefilter Syringe Filters are NOT for sterilization procedures. Use a sterile 0.22um filter for sterilization.


Designed for pre-filtering aqueous materials, these sterile disposable syringe filter units are used to prefilter small volumes (up to 100ml) to remove viscous material and particulates from samples.  All units are packaged in sterile individual blister packs, ready to be used.  Each unit is equipped with a female luer-lok inlet for easy attachment to a standard syringe (or another syringe filter in tandem).  Prefilter is sonically welded to the acrylic housing for strength and to provide bi-directional capability.
