Cellulose Qualitative Filter Paper Discs, Grade DME07, 8.0-12.0um, 42mm, Fast, 100/Pk
GVS SKU: FP042DME07QALC01

Featuring a fast-filtration ashless hardened cellulose medium, these Grade DME07 qualitative filter paper discs provide reliable particle separation for routine analytical work. Each 42mm disc delivers a nominal particle retention of 8.0 to 12.0 microns and is naturally hydrophilic for rapid sample wet-out. The paper is manufactured from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, and carries a low ash content of less than 0.06% that is not reduced by post-treatment.

Key Cellulose Filter Paper Characteristics

• Fast filtration speed: Grade DME07 is a standard fast-filtration medium suited to a wide variety of routine analytical applications.
• Nominal retention 8.0 to 12.0 microns: separates coarse to medium particulates for qualitative determination and material identification.
• Hydrophilic structure: the cellulose matrix wets out readily for consistent flow.
• Low ash content under 0.06%: a high-purity, hardened paper made from refined pulp and pure cotton linters with nearly 100% alpha-cellulose.
• Ashless hardened construction: provides enhanced mechanical strength and reliability during handling.

Key Format Characteristics

• Material: ashless hardened cellulose filter paper.
• Diameter: 42mm disc format.
• Nonsterile: supplied ready for routine laboratory use.
• Pack: 100 discs per box.

These discs maintain consistent retention and flow across routine filtrations, supporting dependable separation of solids from liquids. The hardened cellulose structure provides mechanical strength for handling in funnels and during transfer, helping preserve sample integrity throughout qualitative analysis.

• Qualitative Analysis Cellulose discs support qualitative analytical techniques used to determine and identify materials in routine laboratory work.
• Liquid Clarification The fast-filtration medium clarifies liquids and separates suspended solids quickly across general lab samples.
• Soil Analysis and Seed Testing The 8.0 to 12.0 micron retention handles agricultural soil analysis and seed testing procedures.
• Food Analysis The discs separate solid foodstuffs from associated or extracting liquid in routine food industry techniques.
• Precipitate Filtration The medium captures coarse to medium precipitates during routine analytical separations.
• Air and Dust Monitoring Cellulose discs collect atmospheric dust for stain-intensity and contaminant monitoring.
