Cellulose Qualitative Filter Paper Discs, Grade DMS02, Medium-Slow, 7-8um, 110mm, 100/Pk
GVS SKU: FP110DMS02QALC01

Featuring a low ash hardened cellulose medium made from refined pulp and pure cotton linters, these 110mm qualitative filter paper discs deliver medium-slow filtration with a nominal particle retention of 7 to 8 microns. The paper measures 190 microns thick and carries a nominal basis weight of 100 g/m2, providing the absorbency and loading capacity needed for fine precipitates. Each pack contains 100 discs.

Key Cellulose Filter Paper Characteristics

• Made of refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100 percent for diverse filtration properties.
• Low ash content of less than 0.06 percent, which is not reduced by post-treatment, supporting clean qualitative analysis.
• Slightly more retentive and absorbent than the faster Grade DME01, giving a moderate to slow filtration speed.
• Increased thickness provides added wet strength and allows higher solute loading for difficult-to-clarify samples.
• Hardened texture supports use as a folded filter in analytical funnels.

Key Construction Characteristics

• Disc format, 110mm diameter, supplied flat for funnel and Buchner applications.
• Nominal thickness of 190 microns with a nominal basis weight of 100 g/m2.
• Nominal particle retention range of 7 to 8 microns.
• Nonsterile, packaged 100 discs per box.

These discs deliver consistent, reproducible separations for routine qualitative laboratory work. The hardened low ash construction minimizes contamination of analytical results while the medium-slow flow captures fine precipitates reliably. Their absorbency and loading capacity make them well suited for liquids that are hard to clarify.

• Fine Precipitate Filtration The 7 to 8 micron retention captures fine precipitates such as those encountered in routine analytical separations.
• Soil Analysis The medium-slow, absorbent paper is commonly used for soil testing and related agricultural sample preparation.
• Air and Atmospheric Monitoring Suitable for monitoring specific contaminants in the atmosphere when used as circles or in folded form.
• Clarifying Difficult Liquids The added thickness and loading capacity help clarify essences, oils, tinctures, and other hard-to-filter liquids.
• General Qualitative Analysis Low ash hardened cellulose supports qualitative analytical techniques to identify and determine materials.
• Funnel Filtration The hardened texture makes the disc well suited for use as a folded filter in analytical and Buchner funnels.
