GVS Filter Paper, Disk, 47mm, Glass Fiber, Grade FB, 1.0µm 100/PK FP047DAM10GLFC01

Ashless quantitative filter paper disk designed for critical gravimetric and quantitative analysis. It provides very slow flow and high retention for the collection of fine analytical precipitates and is suitable for use with Buchner funnels and filtration under pressure. The product is intended for analytical precipitates such as barium sulphate, metastannic acid and finely precipitated calcium carbonate and for applications requiring high-purity, low-ash filtration.

Key Features:

• Diameter: 125 mm
• Box quantity: 100 discs
• Retention range: 2–4 µm
• Filtration time (distilled water): 292 seconds
• Thickness: 160 µm
• Weight: 80 g (basis weight)
• Wet bursting strength: 52 kPa

Advantages:

• Very slow flow and high retention enable reliable collection of fine precipitates for accurate gravimetric analysis.
• Ashless composition and high purity minimize residue and contamination in quantitative determinations.
• Enhanced mechanical and wet strength support handling and use under vacuum or pressure filtration without tearing.
