GVS Filter Paper, Disk, 47mm, Glass Fiber, Grade FA, 1.6µm 100/PK FP047DFAFAGLFC01

Quantitative ashless filter paper disc designed for laboratory filtration and gravimetric/quantitative analysis. The 125 mm, medium (Grade 43) disc provides controlled medium retention and flow for collection of precipitates and clarification of liquids. Suitable for use in Büchner funnels and filtration under pressure, it is intended for critical analytical workflows that require low ash and reliable mechanical performance.

Key Features:

• Grade: Quantitative (Ashless), Medium (Grade 43)
• Diameter: 125 mm
• Box quantity: 100 discs
• Retention range: 14–17 µm
• Filtration time (distilled water): 50 seconds
• Thickness: 180 µm
• Wet bursting strength: 30 kPa

Advantages:

• Very low ash formulation minimizes contaminant introduction during gravimetric analysis.
• Enhanced mechanical strength and wet bursting resistance enable use with Büchner funnels and filtration under pressure.
• Medium retention/flow balance enables efficient collection of fine precipitates while maintaining reasonable filtration time.
• Manufacturer quality and consistency support reproducible results in critical quantitative assays.
