Qualitative Filter Paper Discs, Grade DME01, 7-11um Retention, 55mm, Low Ash, 100/Pk
GVS SKU: FP055DME01QALC01

Featuring a refined cellulose depth medium made from pure pulp and cotton linters with an alpha-cellulose content of nearly 100%, this Grade DME01 qualitative filter paper delivers dependable clarification across routine laboratory work. Each 55mm disc provides medium retention in the 7 to 11 micron range with a balanced, medium filtration speed, and the hydrophilic structure wets readily for fast, even flow. The low ash content of less than 0.06% minimizes residue that could interfere with downstream analysis. Supplied 100 discs per pack.

Key Filter Paper Media Characteristics

• Naturally hydrophilic cellulose wets quickly and supports consistent, even flow during gravity and funnel filtration.
• Medium particle retention in the 7 to 11 micron range suits a broad spread of general-purpose separations.
• Low ash content under 0.06% leaves minimal residue, supporting clean qualitative work.
• Nearly 100% alpha-cellulose construction from refined pulp and cotton linters provides uniform structure and reliable mechanical strength.
• Medium filtration speed balances throughput with effective capture of fine precipitates.

Key Construction Characteristics

• Diameter: 55mm circle format.
• Grade: DME01 qualitative, medium speed.
• Material: refined cellulose (pulp and cotton linters).
• Pack: 100 discs per pack, nonsterile.

This filter paper maintains consistent retention and flow from disc to disc, helping preserve sample integrity through routine clarification and analytical separation. Its low ash, high-purity cellulose structure makes it well suited to a wide range of everyday laboratory filtration tasks.
