Glass Fiber Filters, 1.0um, 142mm, Hydrophilic, Nonsterile, 25/Pk
GVS SKU: 1215567

Featuring a binder-free borosilicate glass microfiber depth medium, these 142mm filter discs deliver a 1.0um nominal particle retention for clarifying and prefiltering heavily loaded aqueous and solvent samples. The naturally hydrophilic media wets out readily and its open depth structure provides high dirt-holding capacity with low resistance to flow, making it well suited to protecting and extending the life of downstream membranes. Because the construction is binder-free, the discs avoid binder extractables, making them appropriate for solvent filtration and gravimetric analysis. Supplied nonsterile, 25 discs per pack.

Key Glass Fiber Media Characteristics

• Naturally hydrophilic borosilicate glass fiber wets out quickly for fast, consistent throughput.
• 1.0um nominal particle retention traps fine particulates while maintaining high flow rates.
• Depth structure with large internal surface area provides high particulate loading capacity for heavily contaminated samples.
• Binder-free composition avoids binder extractables, suiting it to solvent filtration and gravimetric determinations.
• Biologically inert media offers broad compatibility with aqueous samples and organic solvents.

Key Construction Characteristics

• Format: 142mm diameter disc.
• Media thickness: 0.45mm.
• Sterility: Nonsterile.
• Pack: 25 discs per pack.

These discs provide reliable, repeatable clarification across a wide range of laboratory samples while preserving filtrate integrity. The high-capacity depth medium handles demanding particulate loads without rapid blinding, helping to safeguard analytical results and downstream filtration steps.

• Prefiltration Removes coarse and fine particulates ahead of final membrane filters to extend their service life when processing heavily loaded samples.
• Environmental Sample Preparation Clarifies water, wastewater, and air pollution monitoring samples prior to analysis.
• Sample Clarification Provides low-cost clarification of turbid aqueous and solvent solutions for laboratory workflows.
• Gravimetric Analysis Binder-free media supports suspended solids and gravimetric determinations without binder extractables.
• Cell and Culture Filtration Filters algae, bacteria cultures, and protein-containing solutions where high particulate loading is expected.
• Solvent Filtration Handles organic solvent samples thanks to its biologically inert, binder-free borosilicate construction.
