Qualitative Filter Paper Discs, 320mm, 8-12um Retention, Folded, Cellulose, 100/Pk
GVS SKU: FP320DME07QALC0F

Featuring a hardened, low-ash cellulose medium engineered for fast filtration, these 320mm qualitative filter paper discs deliver a particle retention range of 8 to 12 microns for routine analytical separations. The pre-folded (fluted) format increases the effective filtration surface area, improving flow rate and loading capacity compared to equivalent flat discs while speeding setup in analytical funnels. Each disc is built from refined pulp and cotton linters with a near-100 percent alpha-cellulose content, supplied 100 per box.

Key Cellulose Media Characteristics

• Fast filtration speed suited to a wide variety of routine qualitative analytical techniques across multiple industries.
• 8 to 12 micron particle retention for clarifying liquids and separating coarser precipitates.
• Hardened, low-ash construction with an ash content of less than 0.06 percent that is not reduced by post-treatment.
• High alpha-cellulose purity made from refined pulp and pure cotton linters for consistent, reliable analytical results.
• Naturally hydrophilic medium that wets quickly with aqueous samples.

Key Construction Characteristics

• Material: qualitative cellulose filter paper.
• Diameter: 320mm circular disc.
• Format: pre-folded (fluted) for use in analytical funnels.
• Sterility: nonsterile.
• Pack: 100 discs per box.

These discs provide dependable, repeatable performance for general laboratory clarification and qualitative identification work. The folded geometry maintains high throughput and increased dirt-holding capacity, helping preserve sample integrity during gravity or funnel filtration.
