GVS Filter Paper, Disk, 42mm, Low Ash-Very Fast, Grade 04, 100/PK FP042DXF04QALC01

Qualitative filter paper disc designed for laboratory filtration and clarification. It provides medium-slow, thick filtration for fine particle retention and high loading capacity, making it suitable for liquids that are hard to clarify such as essences, oils and tinctures. The disc format is appropriate for use in Büchner funnels and routine qualitative analytical separations.

Key Features:

• Diameter: 110 mm
• Grade: 03 — Medium-slow filtration (thick)
• Retention range: 5 µm
• Thickness: 180 µm
• Pack quantity: 100 discs per box
• Filtration time (distilled water): 60 seconds
• Wet bursting strength: 5 kPa

Advantages:

• Fine particle retention and excellent loading capacity for processing suspensions that are difficult to clarify
• Extra thickness gives increased wet strength for improved handling and suitability in Büchner funnel applications
• Consistent medium-slow flow rate that balances retention and reasonable throughput for routine laboratory separations
