GVS Filter, Disk, NC, 0.22µm, White, Gridded, 47mm 100/PK 1214839

Qualitative, low-ash filter paper disc designed for laboratory filtration and sample clarification. This Grade 03, medium-slow (thick) disc provides fine particle retention and high loading capacity for liquids that are hard to clarify, including essences, oils and tinctures, and is suitable for use in Büchner funnels and general qualitative analytical techniques. The paper is manufactured from refined pulp and pure cotton linters to ensure high alpha-cellulose content and reduced ash contamination.

Key Features:

• Diameter: 70 mm
• Form: Disc
• Grade: 03 — Medium-slow filtration, thick (increased thickness compared with Grade 01)
• Box quantity: 100 per pack
• Low ash content (ash < 0.06%)
• Material: refined pulp and pure cotton linters (nearly 100% alpha-cellulose)

Advantages:

• Fine particle retention and excellent loading capacity for clearer filtrates under demanding conditions
• Increased wet strength from extra thickness enables higher solute loading and use with Büchner funnels
• Low ash content minimizes contamination of filtered samples for qualitative analytical work
