Description

Glass Fiber filter Membrane with Binder (G25),1.0 µm, 47mm diameter, 100/pk
GVS Pre-Sep(TM) Glass Fiber membranes With Binders.
2-3um, 47mm diameter. Composed of borosilicate glass fibers woven into a porous matrix and bonded by an acrylic resin.
This bonding produces a filter that reduces media migration and has the strength required for high-volume aqueous filtrations. 

Features and Benefits

  • biologically inert, autoclavable and highly resistant to oxidizing agents and weak acids.
  • can be used as a prefilter or used alone.
  • Prefilters increase the speed of filtration by trapping large particles before they reach the final membrane filter. When used as a prefilter choose a size slightly smaller in diameter than the main filter to allow the prefilter to fit inside the O-ring or filter funnel holder seal, ensuring a positive membrane seal.
  • When used as the main filter medium, select a diameter of the same size as the filter holder to be used.

    Applications

    Recommended for filtrations of long duration under pressure.

Frequently Asked Questions

This filter is composed of borosilicate glass fibers bonded with an acrylic resin, forming a strong porous matrix. The binder reduces fiber migration and provides the durability required for high-volume aqueous filtration applications.

The GVS 1215577 PreSep membrane is designed for sample clarification and prefiltration in laboratory and industrial workflows. It helps remove coarse particles and high particulate loads, improving filtration speed and protecting downstream membrane filters.

The 1.0 µm nominal retention captures larger particles while maintaining very fast flow rates. This makes it suitable for prefiltration, particulate removal, and long-duration filtration under pressure.

Yes, this membrane can be used either as a prefilter or as the primary filter medium. As a prefilter, it traps larger particles before they reach a finer membrane, increasing throughput and extending final filter life.

The filter is biologically inert, autoclavable, and resistant to oxidizing agents and weak acids, making it suitable for a wide range of laboratory and environmental filtration tasks.
