Centriprep^® Centrifugal Filters

Centriprep^® centrifugal filters 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 and an air-seal cap for sample isolation.
