GVS Filter, Disk, CA, 0.8µm, 47mm, 100/PK 1213358

Quantitative ashless filter paper disc designed for quantitative and critical gravimetric analysis. The disc has a 70 mm diameter and a medium-slow filtration speed with a retention range of 7–9 µm, providing controlled flow for analytical precipitates and difficult filtrations. It is suitable for use with Büchner funnels and filtration under pressure and is intended to deliver reliable particle retention and consistent performance for laboratory filtration tasks.

Key Features:

• Diameter: 70 mm
• Filtration speed: Medium-Slow (filtration time for distilled water: 100 sec)
• Retention range: 7–9 µm
• Grade: Quantitative (ashless)
• Box quantity: 100 discs
• Thickness: 170 µm; Wet bursting strength: 36 kPa
• Kind: Disc

Advantages:

• Ashless, quantitative grade reduces contamination risk for gravimetric and analytical procedures.
• Medium-slow flow with 7–9 µm retention enables reliable capture of fine precipitates and difficult filtrations.
• Enhanced mechanical strength and wet bursting resistance support use with Büchner funnels and filtration under pressure.
• Consistent, manufacturer-specified filtration time and dimensions aid reproducibility in laboratory workflows.
