GVS Filter Paper, Disk, 90mm, Glass Fiber, Grade FA, 1.6µm 100/PK FP090DFAFAGLFC01

Glass fiber disk filter, 25 mm diameter, Grade FB with 1.0 µm nominal retention, supplied 100 per pack. This glass microfiber disc is a laboratory-grade filtration medium made of borosilicate glass fibers with a deep porous structure that provides high impurity retention combined with low filter resistance. Typical applications include air sampling and particle filtration of gases, as well as gravimetric and analytical determinations where 1.0 µm retention is required.

Key Features:

• Diameter: 25 mm
• Filter media: Glass microfiber (borosilicate glass fibers)
• Grade: FB
• Nominal pore size: 1.0 µm
• Pack quantity: 100 per pack
• Temperature resistance up to 500°C (depending on binder)

Advantages:

• High impurity retention due to deep porous glass-fiber structure, enabling effective capture of 1.0 µm particles.
• Low filter resistance combined with large surface area for efficient flow and high dirt-holding capacity.
• Suitable for air sampling and particle filtration of gases as well as analytical and gravimetric determinations.
• High temperature resistance supports use in demanding thermal or chemically resistant applications.
