Featuring a low ash, hardened cellulose medium made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, this 47mm qualitative filter paper disc (Grade DME01) delivers a medium filtration speed with a nominal retention range of 10 to 13um. The naturally hydrophilic paper carries an ash content of less than 0.06% and is supplied 100 discs per pack, making it well suited to routine analytical separations and the clarification of liquids.
Key Filter Paper Characteristics
- Low ash content: Less than 0.06% ash, not reduced by post-treatment, minimizing contamination during qualitative work.
- High-purity cellulose: Manufactured from refined pulp and pure cotton linters with nearly 100% alpha-cellulose for consistent filtration behavior.
- Medium retention and flow: Nominal 10 to 13um retention with a balanced medium filtration speed for general-purpose clarification.
- Naturally hydrophilic: Wets readily with aqueous solutions and common laboratory liquids.
- Hardened structure: Provides wet strength for handling during filtration.
Key Construction Characteristics
- Format: 47mm diameter circular disc.
- Material: Qualitative low ash hardened cellulose filter paper.
- Grade: DME01, the most widely used grade in the qualitative range.
- Pack: 100 discs per pack, nonsterile.
This grade covers a wide range of laboratory applications and is frequently used for clarifying liquids and separating fine precipitates. The medium retention and flow rate make it a dependable choice for routine qualitative analysis where residue weight accuracy is not required. Consistent cellulose purity helps maintain sample integrity throughout the filtration process.
