GVS Filter Paper, Disk, 90mm, Ashless-Medium Slow, Grade 40, 100/PK FP090DMS40QANC01

Glass microfiber filter sheets manufactured from 100% borosilicate glass fibers without binders. Grade DFAFA with 1.6 µm retention provides fine particle capture with fast flow; primary uses include atmospheric particulate monitoring, air sampling, water analysis and wastewater controls, and general laboratory filtration where low extractables are required. The sheets are designed for depth filtration and high dirt-holding capacity while maintaining low filter resistance.

Key Features:

• Dimensions: 203 x 254 mm (sheet)
• Filter media: 100% borosilicate glass microfiber, binder-free
• Grade: DFAFA
• Nominal retention / pore size: 1.6 µm
• Pack quantity: 100 sheets per box
• Temperature resistance: up to 500°C (binder-free glass microfiber)

Advantages:

• High impurity retention with large surface-area depth structure for effective capture of fine particles.
• Low filter resistance enabling faster filtration rates while maintaining fine retention.
• Binder-free construction minimizes extractables, making the product suitable for analytical and gravimetric determinations.
• Suitable for a wide range of applications including atmospheric pollution monitoring, air and water analysis, and high-volume particulate sampling.
