Cellulose Filter Paper Discs, Qualitative, Grade DME01, 7-11um Retention, 150mm, Nonsterile, 100/Pk
GVS SKU: FP150DME01QALC01

Featuring a low-ash hardened cellulose medium made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100 percent, these 150mm qualitative filter paper discs deliver dependable medium-speed filtration for everyday laboratory work. Grade DME01 is the most widely used paper in this qualitative range, offering balanced medium retention and flow rate with a nominal particle retention of 7 to 11 microns. The hydrophilic structure wets readily and clarifies a broad variety of aqueous and common laboratory liquids, and each pack contains 100 discs.

Key Cellulose Media Characteristics

• Hydrophilic cellulose construction: manufactured from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100 percent for consistent, reliable performance.
• Medium retention and flow rate: Grade DME01 captures a nominal 7 to 11 micron particle range while maintaining a practical filtration speed.
• Low ash content: ash content of less than 0.06 percent that is not reduced by post-treatment, minimizing residue in routine separations.
• Hardened qualitative grade: provides good wet strength for handling during clarification of fine precipitates and cloudy suspensions.
• Broad compatibility: suited to aqueous solutions and many common laboratory liquids across analytical, agricultural, and food applications.

Key Construction Characteristics

• Format: 150mm diameter circular discs.
• Material: cellulose, low-ash hardened qualitative paper.
• Sterility: supplied nonsterile.
• Pack: 100 discs per pack.

These discs maintain reproducible retention and flow for routine clarification, soil and water analysis, and food separations. The hydrophilic, low-ash medium supports clean separations with minimal interference, helping preserve sample integrity across a wide range of qualitative laboratory procedures.
