Minisart RC4 Syringe Filter - Perfect Condition

The Sartorius Minisart® RC4: a High-Precision Filtration Solution for Sensitive Medical Solvents and Samples

The Minisart® RC4 syringe filter from Sartorius meets the requirements of research, medical biology and clinical analysis laboratories that handle aqueous or organic solutions requiring very fine filtration. Featuring a regenerated cellulose membrane, this hydrophilic model offers high chemical compatibility with many solvents used in medical environments, including methanol, acetonitrile and hexane. Its 0.2 µm retention capacity ensures the effective removal of fine particles, bacteria and contaminants without impacting the structure of sensitive samples.

With a filtration surface area of 0.07 cm² and a filling volume of 0.17 ml, the RC4 is specially designed for very small volume filtration, making it a strategic choice for purification applications prior to injection or analysis. Its low dead volume (5 µl) limits losses, which is crucial when working with rare or expensive samples. It can withstand a maximum pressure of 600 kPa and autoclaving temperatures of up to 121°C for 30 minutes, allowing it to be used under controlled conditions, including demanding protocols.

In addition to its technical performance, this filter is made entirely of polypropylene, ensuring total compatibility between the support and the membrane. It has no HPLC interference peaks, guaranteeing reliable results for chromatographic analyses. The Minisart RC4 fits perfectly into closed medical circuits thanks to its standardised Luer lock connection, facilitating its integration into automated or manual medical devices. Designed for single use, it avoids any risk of cross-contamination and enhances the safety of protocols in laboratories or hospitals.

Thanks to its rigorous manufacturing and compatibility with a wide range of organic solvents, the Minisart RC4 is an essential tool for healthcare professionals and laboratory technicians. It meets the quality standards required in demanding medical environments and critical analytical protocols.
