Cellulose Qualitative Filter Paper, Grade 02 Medium-Slow, 7-8um Retention, 125mm, 100/Pk
GVS SKU: FP125DMS02QALC01

Featuring a hardened, low ash cellulose medium made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, this Grade 02 (DMS02) qualitative filter paper delivers medium-slow filtration with a 7 to 8 um retention range. Each 125 mm circle measures 190 um thick at a nominal basis weight of 100 g/m2, providing the absorbency and loading capacity needed to capture fine precipitates while maintaining reliable flow. The hydrophilic structure wets readily for use in funnels and folded filter configurations.

Key Cellulose Media Characteristics

• Hardened, low ash cellulose with an ash content of less than 0.06% that is not reduced by post-treatment, minimizing sample contamination.
• Medium-slow filtration speed, slightly more retentive and absorbent than Grade 01, suited to fine precipitates.
• Nominal 7 to 8 um particle retention for capturing fine particulates and precipitates.
• Hydrophilic cellulose matrix that wets quickly for gravity and funnel filtration.
• Made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100% for consistent performance.

Key Construction Characteristics

• Circular disc format at 125 mm diameter for standard funnel fitment.
• Nominal thickness of 190 um with a basis weight of 100 g/m2.
• Often used as a folded filter in an analytical funnel.
• Supplied nonsterile in a convenient pack of 100.

This qualitative grade provides dependable separation of fine precipitates and clarification of difficult liquids across routine laboratory workflows. The hardened, low ash construction supports sample integrity by limiting residue contribution, while the medium-slow flow balances retention with throughput for consistent, repeatable results.
