Minisart® RC25 Syringe Filter 0.45 µm Regenerated Cellulose RC filters are optimized for particle removal in aqueous liquids and solvents. Elimination of particles from your samples prior to HPLC or other chromatographic analysis is essential in order to maintain the integrity of your chromatography column and to maximize its operating lifetime. The Minisart® RC25 is optimized for sample preparation.

Regenerated Cellulose Membrane

The Minisart® RC25 Syringe Filter includes a regenerated cellulose (RC) membrane, which is hydrophilic. The membrane is low adsorption and solvent resistant. It is optimized for aqueous liquids and solvents with a pH of 3-14. As such, the RC membrane is uniquely suited for particle removal in these solvents.

Stability Against DMSO

The Minisart® RC25 Syringe Filter is compatible with and stable against DMSO. It is further compatible with other amides, ketones, esters and ethers.

Optimized for Sample Preparation

Minisart® Syringe Filters like the RC25 are optimized for sample preparation and consist of a polypropylene (PP) housing and membrane components featuring maximum chemical compatibility and minimum extractables to ensure excellent results.

Strict Standards in Manufacturing

Minisart® filters, including the RC25, are manufactured by Sartorius and are required to meet the strictest quality standards. As such, we set the standards in both high flow rates and total throughput.

Key Features of Minisart® RC25

Key features of the Minisart® RC25, like other Minisart® PP Standard Syringe Filters, include the low adsorption of analytes, maximum chemical compatibility and minimum extractables. The Minisart® RC25 Syringe Filter is an easy, reliable choice.
