GVS Filter Paper, Disk, 90mm, Ashless-Fast, Grade 41, 100/PK FP090DFA41QANC01

Qualitative filter paper disk for laboratory filtration, designed for very fast flow-rate applications and low ash content. Suited to rapid filtration of coarse and gelatinous precipitates, routine clean-up of biological fluids and organic extracts, food analysis, and air monitoring where high flow and coarse particle retention are required. The paper is a low-ash, hardened cellulose/cotton-linter product offering enhanced mechanical strength for general analytical and clarification tasks.

Key Features:

• Form: Disc
• Diameter: 185 mm
• Grade/Speed: Very Fast (Grade 04)
• Box quantity: 100 per pack
• Retention range: 15–20 µm
• Filtration time (distilled water): 10 seconds
• Thickness: 210 µm; Wet bursting strength: 30 kPa

Advantages:

• Very fast flow rate enables rapid sample throughput for routine laboratory and food-industry analyses.
• Low ash, hardened cellulose composition minimizes contamination of filtrates and improves mechanical strength for use in funnels and pressure-assisted setups.
• High wet bursting strength and specified thickness provide durability and reliable handling during filtration.
