GVS Filter Paper, Disk, 90mm, Ashless-Slow, Grade 44, 100/PK FP090DSL44QANC01

Qualitative filter paper disc designed for laboratory filtration and qualitative analysis. The disc provides medium-slow filtration suitable for monitoring specific contaminants in the atmosphere, filtration of fine precipitates, soil testing and routine laboratory clarifications. Supplied as low-ash, hardened paper for clean filtrates and reliable handling during analytical procedures.

Key Features:

• Diameter: 240 mm
• Filtration speed: Medium-Slow (Grade 02)
• Retention range: 7–8 µm
• Pack quantity: 100 discs per pack
• Thickness: 180 µm
• Weight: 85 g
• Wet bursting strength: 5 kPa

Advantages:

• Low ash content and hardened texture minimize contamination of filtrate and permit recovery of retained precipitates.
• Medium-slow flow and 7–8 µm retention deliver effective separation of fine precipitates and particulate monitoring applications.
• Large 240 mm diameter discs provide increased filtration area for higher sample volumes and faster processing.
• Supplied in 100/unit packs for consistent laboratory supply and standardized use across routine analyses.
