GVS Filter, Disk, NC, 0.45µm, White, 47mm 100/PK 1215281

Quantitative ashless filter paper disc designed for laboratory gravimetric and quantitative analyses. The disc provides very slow flow and high retention for capture of fine precipitates and is intended for critical gravimetric work, extremely difficult filtrations and analytical precipitates such as barium sulfate and finely precipitated calcium carbonate. Packaged for routine laboratory use where purity and consistent filtration performance are required.

Key Features:

• Diameter: 90 mm
• Grade: Quantitative (Ashless, Very Slow)
• Retention range: 2–3 µm
• Filtration time (distilled water): 292 seconds
• Box quantity: 100 discs
• Thickness: 160 µm
• Wet bursting strength: 52 kPa

Advantages:

• Very slow flow with high retention enables reliable capture of very fine precipitates for accurate gravimetric determinations.
• Ashless composition minimizes residual ash, supporting quantitative and analytical workflows that require low inorganic residue.
• Consistent mechanical strength (52 kPa wet bursting strength) and defined thickness deliver reproducible handling and performance during filtration.
• Supplied in a 100‑disc pack to support repeated laboratory analyses and standardized procedures.
