GVS Filter Paper, Disk, 70mm, Glass Fiber, Grade AH, 1.5µm 100/PK FP070DFAAHGLFC01

GVS Qualitative low-ash hardened filter paper, Grade 02 (Medium-Slow), 150 mm discs are laboratory filter papers used in qualitative analytical techniques to determine and identify materials and for clarifying liquids. The low ash, hardened construction provides enhanced mechanical strength and reliability for routine laboratory filtration, folded funnel use, soil testing and monitoring specific contaminants in the atmosphere.

Key Features:

• Diameter: 150 mm
• Filtration properties: Medium-Slow (Grade 02)
• Retention range: 7–8 µm
• Box quantity: 100 discs
• Ash content: < 0.06%
• Thickness: 180 µm

Advantages:

• Low ash content minimizes introduction of contaminants during filtration.
• Hardened construction delivers enhanced mechanical strength and reliability for folded funnel and routine laboratory use.
• Medium-slow retention balances fine particle capture with practical flow rate for soil testing, atmospheric monitoring and clarification tasks.
