Cellulose Qualitative Filter Paper Discs, Grade DME07, 10-13um Retention, 110mm, 100/Pk
GVS SKU: FP110DME07QALC01

Featuring a hardened, ashless cellulose medium made from refined pulp and pure cotton linters, this Grade DME07 qualitative filter paper disc delivers fast filtration for routine analytical work. Each 110mm disc provides a nominal particle retention range of 10 to 13 microns, a nominal thickness of 190 microns, and a basis weight of 85 g/m squared. The near 100 percent alpha-cellulose construction and low ash content make it well suited to a broad range of laboratory clarification and identification tasks.

Key Cellulose Filter Paper Characteristics

• Hardened ashless cellulose produced from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100 percent.
• Low ash content of less than 0.06 percent that is not reduced by post-treatment, supporting clean qualitative results.
• Nominal particle retention of 10 to 13 microns with a fast flow rate for general filtration and clarifying liquids.
• Naturally hydrophilic surface that wets readily with aqueous samples.
• Nominal thickness of 190 microns and basis weight of 85 g/m squared for consistent handling and loading capacity.

Key Construction Characteristics

• Format: 110mm diameter circle (disc).
• Grade: DME07, qualitative, fast filtration.
• Sterility: Nonsterile.
• Pack: 100 discs per box.

This filter paper maintains consistent retention and flow across routine filtrations, helping protect sample integrity during clarification and qualitative analysis. Its hardened, low-ash structure provides reliable performance for separating fine precipitates and clarifying liquids in everyday laboratory procedures.
