Description

0.5 mL Ultrafiltration Centrifuge Tubes are designed for rapid concentration, purification, desalting, and buffer exchange of proteins, nucleic acids, antibodies, enzymes, PCR products, and other biological macromolecules in microscale laboratory workflows. Available in 3 kD, 10 kD, 30 kD, 50 kD, and 100 kD MWCO options, the centrifugal filter devices allow efficient processing of small-volume biological samples while maintaining high recovery performance.

Equipped with a modified PES ultrafiltration membrane, the device delivers low protein binding and high recovery performance (>90%), helping reduce valuable sample loss during ultrafiltration. The membrane structure supports efficient concentration and purification while minimizing membrane contamination and solute polarization.

The ultrafiltration centrifuge tube adopts glue-free encapsulation technology and undergoes a 100% air tightness test to help prevent leakage during centrifugation. Designed for durability and repeated laboratory use, the device demonstrates excellent pH 0–14 acid and alkali resistance and supports reusable performance for more than 20 times under appropriate operating conditions.
