The Thermo Scientific™ Pierce™ Protein Concentrators are disposable ultrafiltration centrifugal devices that provide reliable and consistent results for concentrating, diafiltratingǰ and buffer exchanging of biological samples such as proteins and nucleic acids. The 5–20 mL Concentrators have a built-in dead stop and contain a vertical low protein-binding, highȬflux polyethersulfone (PES) membrane, which allows for processing of volumes between 5 mL and 20 mL. The PES membrane is available in 5 distinct molecular-weight cutoffs (MWCOs) of 5K, 10K, 30K, 50K, and 100K. The MWCOs are etched on the sides of the Concentrators for easy identificationǰ and a clear window with graduations on the side of each device allows for visual determination of the retentate volum

• Rapid protein concentration—sample concentration of 10- to 30-fold can be achieved in 5 to 30 minutes for 10K MWCO (time may vary for a product with a different MWCO)
• Excellent protein recovery—typical protein recovery is >90%
• Versatility—perform sample concentration, diafiltration, or buffer-exchange of biological samples
• Compatibility—may be used in both fixed angle and swing bucker rotors; collect and recover sample without invert spinning
