Cellulose Qualitative Filter Paper Discs, 5-7um Retention, 240mm, Medium-Slow Thick, 100/Pk
GVS SKU: FP240DMS03QLTC01

Featuring a low ash, hardened cellulose medium made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, this 240mm qualitative filter paper disc delivers medium-slow filtration with the added thickness of the DMS03 grade. With a particle retention range of 5 to 7um, a nominal thickness of 320um, and a nominal basis weight of 200 g/m2, it provides dependable separation of fine precipitates while maintaining strong dirt-holding capacity. The ash content of less than 0.06% is not reduced by post-treatment, supporting clean, reproducible qualitative work.

Key Cellulose Filter Paper Characteristics

• Hydrophilic cellulose medium made from refined pulp and pure cotton linters with nearly 100% alpha-cellulose content
• Particle retention range of 5 to 7um for capturing fine precipitates
• Medium-slow flow with the doubled thickness of the DMS03 grade for increased loading capacity
• Low ash content of less than 0.06%, not reduced by post-treatment
• Hardened structure providing enhanced mechanical strength for routine and pressure filtration

Key Construction Characteristics

• 240mm diameter disc format
• Nominal thickness of 320um
• Nominal basis weight of 200 g/m2
• Nonsterile, supplied 100 discs per box
• Suitable for Buchner funnels and filtration under pressure

This filter paper maintains consistent retention and flow across routine qualitative separations, helping protect sample integrity during clarification of liquids and collection of fine precipitates. The hardened, low ash construction withstands demanding filtration while keeping background contamination low. Each disc provides reliable, reproducible performance for analytical and general laboratory filtration.

• Fine Precipitate Filtration The 5 to 7um retention range effectively captures fine precipitates such as those encountered in inorganic and gravimetric workflows.
• Soil Analysis The medium-slow thick DMS03 grade suits soil testing procedures where higher loading capacity is beneficial.
• Atmospheric Contaminant Monitoring The medium provides a suitable surface for monitoring specific contaminants collected from the atmosphere.
• Liquid Clarification The hydrophilic cellulose medium clarifies aqueous solutions and common laboratory liquids during routine sample preparation.
• Qualitative Analytical Separations The low ash hardened paper supports qualitative techniques used to determine and identify materials.
• General Laboratory Filtration Compatible with Buchner funnels and filtration under pressure for everyday laboratory separation tasks.
