GVS Filter Paper, Disk, 47mm, Ashless-Medium Slow, Grade 40, 100/PK FP047DMS40QANC01

Qualitative filter paper discs for laboratory filtration and gravimetric analysis. The discs provide very fast flow for separation of coarse and gelatinous precipitates and are suitable for routine analytical filtrations, air pollution monitoring where fine-particle collection is not critical, and cleanup of biological fluids or organic extracts. The product is a 110 mm diameter disc supplied in packs of 100 and designed for applications requiring rapid clarification and low ash contamination.

Key Features:

• Diameter: 110 mm
• Filtration speed: Very Fast (filtration time for distilled water: 10 seconds)
• Retention range: 15–20 µm
• Thickness: 210 µm
• Basis weight: 85 g/m²
• Wet bursting strength: 30 kPa
• Pack quantity: 100 discs

Advantages:

• Very fast filtration reduces processing time for routine separations and clarifications.
• Low ash formulation minimizes introduction of contaminants during analytical and gravimetric procedures.
• Robust wet bursting strength supports use with Büchner funnels and vacuum or pressure-assisted filtration.
• 110 mm disc format in 100‑piece packs simplifies handling and consistent sample processing.
