Qualitative Filter Paper, Grade DME01, Medium Flow, 7-11um Retention, 70mm, Low Ash, 100/Pk
GVS SKU: FP070DME01QALC01

Featuring a low-ash, hardened cellulose medium made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100 percent, this Grade DME01 qualitative filter paper delivers balanced retention and flow for everyday laboratory work. Supplied as 70mm circles in packs of 100, the medium-flow paper offers a particle retention range of 7 to 11 microns and is naturally hydrophilic, making it well suited to routine clarification and qualitative analytical separations.

Key Filter Paper Media Characteristics
