GVS Filter Paper, Disk, 47mm, Glass Fiber, Grade AH, 1.5µm 100/PK FP047DFAAHGLFC01

Quantitative ashless filter paper disc for laboratory filtration, supplied as 125 mm diameter circles for use in gravimetric and quantitative analyses. The paper provides medium-slow flow (Medium-Slow) with high purity and enhanced mechanical strength, suitable for critical gravimetric analysis, preparation of samples for spectroscopic and atomic absorption procedures, and general quantitative filtration tasks. Designed for use with Buchner funnels and filtration under pressure when an ashless, high-purity disc is required.

Key Features:

• Diameter: 125 mm
