Cellulose Qualitative Filter Paper, 10-13um Retention, 125mm Disc, Medium, 100/Pk
GVS SKU: FP125DME01QALC01

Featuring a low-ash cellulose medium made from refined pulp and pure cotton linters with an alpha-cellulose content near 100%, this 125mm qualitative filter paper disc delivers balanced medium retention and flow for everyday laboratory filtration. With a nominal particle retention of 10 to 13 microns, a thickness of 190 microns, and a basis weight of 85 g/m2, it provides dependable clarification of liquids and routine separation of precipitates. Each disc carries an ash content of less than 0.06 percent that is not reduced by post-treatment, and the medium offers a wet bursting strength of 5 kPa.

Key Cellulose Media Characteristics

• Made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100 percent for high purity.
• Medium retention range of 10 to 13 microns paired with a medium flow rate for general-purpose qualitative work.
• Low ash content of less than 0.06 percent that is not reduced by post-treatment.
• 190 micron thickness and 85 g/m2 basis weight provide a robust, absorbent depth structure.
• Naturally hydrophilic and compatible with aqueous solutions and common laboratory liquids.

Key Construction Characteristics

• 125mm diameter circular disc format suited to standard funnels and Buchner setups.
• Qualitative grade with a wet bursting strength of 5 kPa for handling during wet filtration.
• Nonsterile, supplied 100 discs per box.

This medium-speed qualitative paper maintains consistent retention and flow across routine clarification and precipitate separation tasks. The high alpha-cellulose, low-ash composition supports clean, reproducible results in qualitative analytical work where residue weight accuracy is not required.
