Celltreat 230722 Centrifugal Filter Unit 15mL, MWCO 10kDa, Non-Sterile, 8/pk

This centrifugal filter unit is designed for sample concentration and purification workflows in research and clinical labs. Typical uses include protein concentration, buffer exchange, desalting, and molecular fractionation where separation by molecular weight is required.

The 10 kDa molecular weight cut-off indicates the membrane will retain molecules larger than approximately 10 kilodaltons while allowing smaller molecules to pass through. This makes the unit suitable for concentrating proteins and biomolecules above that size threshold.

The filter cartridge uses a PES (polyethersulfone) membrane, which provides high flow rates and low protein binding. This helps maximize sample recovery and supports efficient processing of biological samples.

The unit incorporates a large active membrane area and dual vertical design to promote fast filtration. It also includes internal tube supports and clear graduations to improve handling accuracy during centrifugation workflows.

This model is supplied non-sterile and is intended for use in standard centrifuge tube rotors. It operates within typical laboratory conditions (about 0 °C to 40 °C) and is compatible with common benchtop centrifuges designed for 15 mL filter units.
