Cellulose Qualitative Filter Paper, Grade 01, 10-13um, 150mm, Folded, Nonsterile, 100/Pk
GVS SKU: FP150DME01QALC0F

Featuring a low-ash cellulose medium made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, this 150mm qualitative filter paper delivers medium retention and medium filtration speed for routine analytical separations. The Grade 01 (DME01) paper provides a nominal particle retention of 10 to 13 um and is supplied in a pre-folded format for fast setup in conical funnels, with 100 circles per pack.

Key Cellulose Media Characteristics

• Naturally hydrophilic cellulose medium that wets readily with aqueous samples
• Medium nominal particle retention of 10 to 13 um with a balanced medium filtration speed
• Low ash content of less than 0.06%, not reduced by post-treatment, for cleaner qualitative work
• Constructed from refined pulp and pure cotton linters with near-100% alpha-cellulose for consistent purity
• Suited to a wide range of routine laboratory clarification and precipitate filtration tasks

Key Construction Characteristics

• 150mm diameter circles for use with standard analytical and conical funnels
• Pre-folded format that speeds funnel loading and increases effective filtration surface
• Nonsterile, supplied 100 circles per pack
• Cellulose composition compatible with general aqueous laboratory samples

This Grade 01 paper maintains reliable, repeatable performance across clarifying liquids and routine precipitate filtration. The medium retention and steady flow help protect downstream steps while preserving sample integrity, making it a dependable choice for general qualitative analysis.
