      DescriptionCentriprep Centrifugal Filter Unit
      Background InformationCentriprep® centrifugal filters are disposable ultrafiltration devices used for purifying, concentrating, and desalting biological samples in the 2–15 mL volume range. 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.
