Thumbnail Filmstrip of Cellulose Qualitative Filter Paper, Grade DMS03, 5-7um Retention, 90mm, Nonsterile, 100/Pk Images
Featuring a thick, refined cellulose depth medium made from pure pulp and cotton linters with an alpha-cellulose content of nearly 100%, this Grade DMS03 qualitative filter paper delivers medium-slow filtration with a nominal particle retention range of 5 to 7 microns. The 90mm circle measures 320 microns thick with a nominal basis weight of 200 g/m2, providing roughly double the thickness of standard medium-grade papers for increased wet strength and higher solute loading. A nominal ash content of less than 0.06% supports clean qualitative work.
Key Cellulose Media Characteristics
- Naturally hydrophilic refined pulp and cotton linter structure with nearly 100% alpha-cellulose content
- Medium-slow flow with a nominal particle retention range of 5 to 7 microns
- Extra thickness of 320 microns provides increased wet strength and higher solute loading capacity
- Nominal basis weight of 200 g/m2 supports fine particle retention and excellent loading
- Nominal ash content below 0.06%, not reduced by post-treatment
Key Construction Characteristics
- Cellulose qualitative filter paper, Grade DMS03 (Medium-Slow, Thick)
- 90mm diameter circle format
- Supplied nonsterile
- Packaged 100 circles per box
This thick, medium-slow paper maintains fine particle retention while withstanding the demands of difficult clarifications. The extra thickness allows it to handle higher solute loads without breakthrough, helping protect sample integrity across routine qualitative separations and clarification tasks.
