GVS Filter Paper, Disk, 90mm, Low Ash-Very Fast, Grade 04, 100/PK FP090DXF04QALC01

Glass microfiber, binder-free 47 mm disc filter with 1.5 µm retention for laboratory and environmental sampling. It is designed for general-purpose laboratory filtration, air sampling to collect atmospheric particulates and aerosols, water analysis and high-volume PM-10 sampling. The depth structure and large surface area provide high impurity retention combined with low filter resistance.

Key Features:

• Diameter: 47 mm
• Retention: 1.5 µm
• Filter media: 100% borosilicate glass fiber (binder-free)
• Pack quantity: 100 discs per box
• Temperature resistance: up to 500°C
• Weight: 53 g/m²

Advantages:

• Outstanding impurity retention with low filter resistance due to depth-structured glass microfiber
• Effective at adsorbing very fine particles (down to ~1 µm) for accurate air and aerosol sampling
• High temperature resistance (up to 500°C) enables use in applications requiring thermal stability
• Suitable for a range of applications including general laboratory filtration, water analysis and high-volume PM-10 sampling
