Featuring a refined cellulose medium made from pure pulp and cotton linters, these 47mm qualitative filter paper discs deliver the maximum degree of fine particle retention in the GVS qualitative range. Designated Grade 05 (DXS05), this very slow filtration paper provides a nominal 3um particle retention with a hydrophilic structure that captures extra fine-grained precipitates while clarifying difficult, cloudy suspensions. Each pack contains 100 discs supplied nonsterile for routine analytical and clarification work.
Key Cellulose Media Characteristics
- Manufactured from refined pulp and pure cotton linters with a near 100% alpha-cellulose content for consistent qualitative performance.
- Grade 05 (DXS05) provides the lowest filtration rate and the maximum degree of fine particle retention in the qualitative range.
- Naturally hydrophilic structure wets out readily for aqueous filtration and clarification.
- Nominal 3um retention isolates extra fine-grained precipitates such as barium sulphate and cupreous oxide.
- Suited to demanding clarification of cloudy suspensions, including water and soil analysis samples.
Key Construction Characteristics
- 47mm diameter circular discs sized for standard funnels and filtration setups.
- Qualitative grade cellulose paper for analytical separation and identification work.
- Supplied nonsterile in a convenient pack of 100 discs.
This very slow grade trades flow rate for retention, capturing the smallest particulates encountered in the qualitative range to maintain sample clarity. The high-purity cellulose construction supports reliable, repeatable filtration across analytical and clarification procedures. Its fine porosity makes it the preferred choice when difficult, hard-to-clarify samples must be reduced to a clean filtrate.
