Centriprep® Centrifugal Filter

Centriprep® centrifugal filter devices are disposable ultrafiltration devices used for purifying, concentrating, and desalting biological samples in the 2–15 mL volume range. 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. Centriprep® devices consist of a sample container with a twist-lock cap, a filtrate collector containing a low adsorptive Ultracel® regenerated cellulose membrane, plus an air-seal cap for sample isolation.
