Qualitative Filter Paper Discs, Medium-Slow, 5-7um, 150mm, Grade DMS03, 100/Pk
GVS SKU: FP150DMS03QLTC01

Featuring a thick, low-ash cellulose depth medium made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, these Grade DMS03 qualitative filter paper discs deliver medium-slow filtration with a nominal particle retention of 5 to 7 microns. Each 150mm circle provides roughly double the thickness of a standard medium-grade paper, giving it excellent dirt-holding capacity for fine precipitates and heavily loaded samples. The hydrophilic cellulose structure wets readily with aqueous samples and maintains an ash content of less than 0.06%, which is not reduced by post-treatment.

Key Cellulose Media Characteristics

• Refined pulp and pure cotton linter construction with an alpha-cellulose content of nearly 100% for consistent, reproducible filtration.
• Nominal particle retention of 5 to 7 microns suited to clarifying liquids and capturing fine precipitates.
• Medium-slow filtration speed with extra thickness for high particulate loading without premature clogging.
• Hydrophilic surface that wets quickly with aqueous and most polar samples.
• Low ash content of less than 0.06% that is not reduced by post-treatment.

Key Construction Characteristics

• Grade DMS03 medium-slow, thick qualitative cellulose paper.
• 150mm diameter circle format for funnel and Buchner filtration.
• Nominal thickness of 320 microns with a basis weight of 200 g/m squared.
• Nonsterile, supplied 100 discs per box.

This grade delivers dependable separation of solids from liquids across routine qualitative work, holding more precipitate without clogging thanks to its increased thickness. The uniform cellulose structure helps maintain sample integrity and reproducible results in soil analysis, food testing, and air monitoring applications.

• Clarifying Liquids Separates fine suspended solids and precipitates from aqueous samples for clearer downstream analysis.
• Soil Analysis Filters soil extracts and suspensions where medium-slow retention of fine particles is required.
• Fine Precipitate Filtration Captures fine precipitates with high loading capacity due to the thick depth structure.
• Food Analysis Separates solid foodstuffs from associated liquids in routine quality testing.
• Air and Atmospheric Monitoring Collects atmospheric dust and contaminants for photometric or gravimetric evaluation.
• Qualitative Analytical Separations Supports teaching and routine laboratory identification of materials where residue mass is not critical.
