GVS Filter Paper, Disk, 90mm, Low Ash-Medium Slow, Grade 02, 100/PK FP090DMS02QALC01

Quantitative ashless filter paper disc designed for critical gravimetric and quantitative laboratory filtration. The disc provides medium-slow flow suitable for analytical precipitates and extremely difficult filtrations, and is intended for use with Buchner funnels and pressure-assisted filtration. Typical applications include quantitative analysis and recovery of fine precipitates in laboratory workflows.

Key Features:

• Diameter: 47 mm
• Filter type: Disc, Quantitative (ashless, hardened)
• Filtration speed: Medium-Slow (filtration time for distilled water: 100 sec)
• Retention range: 7–9 µm
• Box quantity: 100 per pack
• Thickness: 170 µm
• Wet bursting strength: 36 kPa

Advantages:

• Extremely low ash content from acid-hardened, ashless manufacture minimizes contamination of analytical precipitates.
• Medium-slow flow and 7–9 µm retention provide reliable capture of fine precipitates for gravimetric and quantitative analyses.
• Enhanced mechanical strength and hardened texture improve handling and make the disc suitable for Büchner funnels and filtration under pressure.
• Consistent manufacturer-controlled dimensions and performance support reproducible laboratory results.
