GVS Filter Paper, Disk, 47mm, Glass Fiber, Grade FF, 0.7µm 100/PK FP047DSLFFGLFC01

Qualitative filter paper discs for laboratory filtration and analytical separations. These 125 mm, low-ash, medium-slow (Grade 02) discs provide medium-slow filtration with 7–8 µm particle retention and are intended for general filtration tasks such as monitoring specific contaminants in the atmosphere, filtration of fine precipitates, soil testing and use as folded filters in analytical funnels.

Key Features:

• Diameter: 125 mm
• Pack quantity: 100 discs per box
• Filtration speed: Medium-Slow (Grade 02); filtration time for distilled water: 60 seconds
• Retention range: 7–8 µm
• Thickness: 180 µm
• Ash content: low (ashless/acid-washed production process)
• Kind: Disc

Advantages:

• Low ash content minimizes contamination when filtering and supports accurate analytical results.
• Medium-slow retention (7–8 µm) balances fine particle capture with reasonable flow for precipitate and soil analyses.
• Standard 125 mm diameter and 100-disc pack size support routine laboratory workflows and use in analytical funnels.
• Hardened/washed production process increases strength for recoverable precipitates and suitability in analytical filtration.
