GVS Filter, Disk, CA, 0.45µm, 293mm, 25/PK 1212620

Qualitative filter paper disk for laboratory filtration, supplied in packs of 100. The disc is a low-ash, hardened grade 04 filter with a very fast flow rate designed for general qualitative analytical techniques, clarifying liquids, routine cleanup of biological fluids and food-industry analysis. It is intended for rapid filtration of coarse and gelatinous precipitates and for applications where high throughput and minimal residue are required.

Key Features:

• Diameter: 47 mm
• Grade: Qualitative (Grade 04, Very Fast)
• Retention range: 15–20 µm
• Filtration time (distilled water): 10 seconds
• Thickness: 210 µm; Weight: 85 g
• Box quantity: 100 discs; Wet bursting strength: 30 kPa

Advantages:

• Very fast flow rate enables rapid sample processing and high throughput.
• Low ash, hardened composition minimizes contamination and facilitates recovery of precipitates.
• High wet bursting strength and reinforced texture improve mechanical durability during filtration.
