Glass Fiber Syringe Filters, 1.0um, 47mm, Nonsterile, 500/Pk
GVS SKU: 1215589

Featuring a binder-free borosilicate glass microfiber depth medium, these 47mm filter discs deliver 1.0um nominal particle retention with the fast flow rates and high loading capacity characteristic of glass fiber media. Composed of borosilicate glass fibers woven into a porous matrix without bonding resin, the binder-free construction avoids binder extractables during solvent filtration and gravimetric analysis, making it well suited for analytical and gravimetric determinations. Each pack contains 500 hydrophilic discs.

Key Glass Fiber Media Characteristics

• Binder-free borosilicate glass microfiber depth medium providing 1.0um nominal particle retention.
• Naturally hydrophilic for aqueous samples, wetting spontaneously without pretreatment.
• High-loading depth structure that traps large particles to extend the life of downstream membranes.
• Biologically inert, autoclavable, and highly resistant to oxidizing agents and weak acids.
• Binder-free composition that minimizes extractables for solvent filtration and gravimetric work.

Key Construction Characteristics

• 47mm diameter disc format compatible with standard filter holders and funnels.
• Nominal media thickness of 0.45mm for robust particulate capacity.
• Temperature stable, withstanding service up to 500 degrees C.
• Supplied nonsterile, 500 discs per pack.

These discs maintain consistent retention and fast filtration across heavily loaded aqueous samples, protecting downstream final membranes and reducing replacement frequency. The binder-free borosilicate structure preserves sample integrity by avoiding resin extractables during solvent and gravimetric procedures. Reliable particulate capture and high flow make them a dependable choice for clarification and prefiltration workflows.

• Prefiltration Extends the life of downstream final membranes by trapping large particles before they reach the final filter.
• Gravimetric Analysis Binder-free borosilicate media avoids extractables for accurate weigh-loss and suspended solids determinations.
• Sample Clarification Provides low-cost clarification of relatively clean aqueous solutions using fast-flow depth filtration.
• Environmental Monitoring Supports water and air pollution sample preparation where high particulate loading is expected.
• Solvent Filtration Resistant to oxidizing agents and weak acids, suited for filtering organic solvents without binder contamination.
• Culture and Protein Filtration Handles filtration of algae, bacteria cultures, and protein-containing samples that quickly load standard membranes.
