These centrifugal filters are disposable ultrafiltration non sterile devices used for purifying, concentrating, and desalting biological samples in the 2 to 15 ml volume range.

• For use with samples containing high levels of solutes
• Unique inverse flow mode of operation with large dead stop
• Fast sample processing
• Fits standard swinging-bucket rotor for 50 ml tubes

They may also be used for filtration applications. These complete, ready-to-use ultrafiltration devices are designed for operation in most centrifuges that can accommodate 50 ml centrifuge tubes. They are easy to use and offer a high flow rate. This devices consist of a sample container with a twistlock cap, a filtrate collector containing a low-adsorptive, Ultracel® regenerated cellulose membrane and an air-seal cap for sample isolation.

Application includes concentration and purification of particle-laden solutions, solutions with high solute concentration, separation of low MW solutes from fermentation broths, cell culture media and lysates.
