Featuring a thick, medium-slow cellulose depth paper made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, this 110mm Grade DMS03 disc delivers a 7-8 micron nominal particle retention with a distilled-water filtration time of 60 seconds. The extra thickness provides increased wet strength and a higher solute loading capacity, making it well suited to liquids that are difficult to clarify. Each box contains 100 discs.
Key Cellulose Media Characteristics
- Made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100% for diverse filtration properties.
- Provides a 7-8 micron nominal particle retention in the medium-slow filtration range.
- Double-thickness construction relative to standard medium grades gives increased wet strength and higher solute loading.
- Low ash content of less than 0.06%, not reduced by post-treatment.
- Hydrophilic structure suited to aqueous samples and routine qualitative work.
Key Construction Characteristics
- 110mm diameter disc format, supplied 100 per box.
- Nominal thickness of 180 microns (0.18mm) with a nominal basis weight of 85 g/m squared.
- Wet bursting strength of 5 kPa.
- Grade DMS03, medium-slow filtration speed with a 60 second distilled-water filtration time.
- Qualitative, nonsterile cellulose paper.
This grade maintains fine particle retention while accommodating heavy solute loads, supporting reliable clarification of essences, oils, tinctures, and other hard-to-clarify liquids. The hardened, thick structure withstands handling during demanding filtrations and helps preserve sample integrity across routine laboratory analyses.

- Clarification of Difficult Liquids The thick, high-loading paper is preferred for clarifying essences, oils, tinctures, and other liquids that are hard to clarify.
- Fine Precipitate Filtration Its 7-8 micron retention captures fine precipitates in routine qualitative separations.
- Soil Analysis Suited to soil testing and the filtration of associated fine particulates in agricultural and environmental labs.
- Atmospheric Contaminant Monitoring Used to monitor specific contaminants in the atmosphere by collecting and retaining airborne particulates.
- General Qualitative Analysis Serves routine qualitative analytical techniques used to determine and identify materials.
- Buchner Funnel Filtration The increased wet strength from the extra thickness supports use in funnels under demanding filtration conditions.
