Cellulose Qualitative Filter Paper, Grade DME01, 125mm, Folded, Medium Retention, 100/Pk
GVS SKU: FP125DME01QALC0F

Featuring a refined cellulose medium made from pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, this Grade DME01 qualitative filter paper is the most widely used grade in its range, delivering medium retention and a medium filtration speed across a broad span of routine laboratory work. Each 125mm disc is supplied in a folded (pre-pleated) format that increases the effective filtration surface for improved flow rate and greater loading capacity compared with equivalent flat filters. With a nominal particle retention of 7 to 11 microns and a low ash content of less than 0.06%, the paper clarifies liquids and captures fine precipitates dependably in qualitative analytical separations.

Key Cellulose Media Characteristics

Made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100% for consistent, high-purity filtration.
Provides medium particle retention of 7 to 11 microns paired with a medium filtration speed suited to general clarification.
Captures fine precipitates such as lead sulphate, calcium oxalate, and calcium carbonate during routine separations.
Low ash content of less than 0.06% that is not reduced by post-treatment, supporting clean qualitative work.
Folded, pre-pleated construction expands surface area to raise flow rate and solute loading capacity.

Key Construction Characteristics

125mm diameter circular disc in a folded (pre-pleated) format ready to seat directly in an analytical funnel.
Cellulose composition delivers reliable absorbency and wet handling for gravity, pressure, or vacuum setups.
Nonsterile and supplied 100 discs per pack.

This Grade DME01 paper supports a wide range of laboratory applications, from clarifying liquids to routine qualitative analytical separations. The folded format maintains steady flow and high particulate loading, helping preserve sample integrity through demanding clarification work. Consistent media composition delivers repeatable results across food, agricultural, environmental, and educational laboratories.
