GVS Filter Paper, Disk, 70mm, Ashless-Medium Slow, Grade 40, 100/PK FP070DMS40QANC01

Quantitative filter paper disc designed for critical gravimetric and quantitative laboratory filtration. It provides medium-slow flow and fine particle retention for analytical precipitates and demanding filtrations, and is suitable for use with Buchner funnels and filtration under pressure. Primary use cases include critical gravimetric analysis and quantitative separations where controlled filtration rate and consistent particle retention are required.

Key Features:

• Diameter: 150 mm
• Filter type: Quantitative (disc)
• Filtration speed: Medium‑Slow (filtration time for distilled water: 100 seconds)
• Retention range: 7–9 µm
• Box quantity: 100 discs
• Thickness: 170 µm
• Wet bursting strength: 36 kPa

Advantages:

• Engineered for critical gravimetric and quantitative analysis, providing consistent analytical performance.
• Medium‑slow flow with 7–9 µm retention for effective capture of fine precipitates.
• Enhanced mechanical strength and reliability for use in Buchner funnels and pressure-assisted filtration.
• Supplied in a pack of 100 discs for laboratory convenience and repeatable workflows.
