Glass Fiber Filter Discs, 1.0um, 21mm, Binder-Free, Nonsterile, 100/Pk
GVS SKU: FP021DAM10GLFC01

Featuring a binder-free borosilicate glass microfiber depth medium, these 21mm filter discs deliver 1.0um nominal particle retention with a media thickness of 0.28mm. The naturally hydrophilic depth structure provides high particulate loading and fast flow, making it well suited to air pollution monitoring and gravimetric determinations where binder extractables must be avoided. Each pack contains 100 discs.

Key Glass Fiber Media Characteristics

• Constructed from 100% borosilicate glass fibers with no binder, eliminating binder extractables during gravimetric and analytical work
• Naturally hydrophilic depth matrix that wets readily and provides high particulate loading capacity
• 1.0um nominal particle retention for fine retention with fast flow
• Biologically inert, autoclavable, and highly resistant to oxidizing agents and weak acids
• Depth structure with large surface area provides outstanding retention capacity combined with low filter resistance

Key Construction Characteristics

• 21mm diameter disc format
• Nominal media thickness of 0.28mm
• Supplied nonsterile
• Packaged 100 discs per box

This depth medium maintains consistent retention across heavily loaded samples while protecting downstream membranes and preserving sample integrity. The absence of binder resin keeps backgrounds clean for gravimetric and trace analyses. Fast flow and high loading capacity make it a dependable choice for repeated air and aqueous sampling.

• Air Pollution Monitoring The binder-free borosilicate medium supports gravimetric determination of airborne particulates and atmospheric pollution control sampling.
• Gravimetric Analysis Absence of binder extractables makes the disc suitable for clean gravimetric and analytical determinations.
• Membrane Prefiltration High particulate loading capacity allows the disc to protect and extend the life of downstream membrane filters.
• Suspended Solids Analysis Fine 1.0um retention with fast flow supports analysis of suspended solids in water and industrial samples.
• Sample Clarification The depth medium clarifies heavily loaded aqueous samples at low cost when used alone.
• Aerosol Sampling The hydrophilic glass fiber structure captures fine particulate from air and gas streams.
