GVS Filter, Disk, NY, 0.22µm, 47mm, 100/PK 1213769

Qualitative filter paper discs for laboratory filtration designed for very slow filtration and maximum fine-particle retention. Suitable for clarification of cloudy suspensions, water and soil analysis, and extra fine-grained precipitates; preferably used in difficult filtration conditions and for clarification tasks such as wine clarification and recovery of fine precipitates. Packaged for routine analytical use in Büchner funnels and similar laboratory filtration setups.

Key Features:

• Diameter: 90 mm
• Grade: 05 (Very Slow filtration)
• Retention range: 3–5 µm
• Filtration time (distilled water): 300 seconds
• Thickness: 170 µm
• Box quantity: 100 discs
