Glass Fiber Filter Discs, 2.7um, 55mm, Binder-Free, Nonsterile, 100/Pk
GVS SKU: FP055DAM27GLFC01

Featuring a 100% borosilicate glass microfiber depth medium, these binder-free filter discs combine fine particle retention with fast flow for demanding air and liquid sampling. Each disc measures 55mm in diameter with a nominal particle retention of 2.7um and a naturally hydrophilic structure, supplied 100 per box. The depth structure of the large surface area provides outstanding impurity retention capacity combined with low filter resistance.

Key Glass Fiber Media Characteristics

• Naturally hydrophilic borosilicate medium wets out readily for aqueous and air monitoring sampling without surfactant treatment.
• Binder-free construction eliminates organic binder extractables, making the medium well suited to gravimetric and analytical determinations.
• Depth-filtration matrix delivers high particulate loading capacity by capturing particles throughout the media thickness rather than on a single surface.
• Biologically inert and autoclavable medium that is highly resistant to oxidizing agents and weak acids.
• 2.7um nominal retention provides fine retention with fast flow for heavily loaded samples.

Key Construction Characteristics

• Material: 100% borosilicate glass microfiber, binder-free.
• Format: 55mm diameter circle.
• Sterility: Nonsterile.
• Pack: 100 discs per box.

This depth medium maintains consistent retention and high flow across heavily loaded samples, protecting downstream membranes and analytical instruments. The binder-free borosilicate structure preserves sample integrity for gravimetric and trace analysis where extractables must be minimized. Reliable particulate capture supports reproducible results in air monitoring and aqueous clarification work.
