Glass Fiber Syringe Filters, 1.0um, 90mm, Nonsterile, 25/Pk
GVS SKU: 1215564

Featuring a hydrophilic borosilicate glass fiber depth medium, these 90mm filter discs deliver 1.0um nominal particle retention for demanding aqueous filtrations. The glass fiber matrix is bonded with an acrylic binder that reduces media migration and provides the strength required for high-volume filtrations. As a depth medium rather than a screen membrane, the structure captures particulate throughout its thickness, supporting high flow rates and heavy particulate loads. Each pack contains 25 nonsterile discs.

Key Glass Fiber Media Characteristics

• Naturally hydrophilic borosilicate glass microfiber medium for fast, efficient aqueous wetting and flow.
• 1.0um nominal particle retention suited to prefiltration of heavily loaded samples rather than absolute screening.
• High dirt-holding capacity from the open depth structure, extending the life of downstream membranes.
• Acrylic binder reduces media migration while maintaining mechanical strength under high-volume conditions.
• Biologically inert and highly resistant to oxidizing agents and weak acids.

Key Construction Characteristics

• 90mm disc format for use in standard filter holders and funnels.
• Borosilicate glass fiber construction with acrylic binder.
• Autoclavable for applications requiring heat sterilization.
• Supplied nonsterile, 25 discs per pack.

These discs maintain dependable flow and consistent retention across high-particulate aqueous samples, protecting downstream filtration steps and preserving sample integrity. Their inert borosilicate composition supports reliable performance with a broad range of aqueous and chemically aggressive samples. Used alone or as a prefilter, the medium delivers low-cost, high-capacity clarification.

• Prefiltration of Heavily Loaded Samples The high dirt-holding depth structure traps large particulates to extend the life of downstream membrane filters.
• Sample Clarification Provides low-cost clarification of turbid aqueous samples prior to analysis.
• Environmental Sample Prep Handles high particulate loads common in water and wastewater suspended solids work.
• High-Volume Aqueous Filtration The binder-strengthened matrix withstands high-volume filtrations under pressure.
• Cell and Culture Filtration Suited to filtration of water, algae, and bacterial culture suspensions.
• Protein Filtration Inert borosilicate medium supports protein-containing sample filtration without adverse interactions.
