Thermo Scientific™ Pierce™ Protein Concentrators PES are disposable ultrafiltration centrifugal devices with a polyethersulfone (PES) membrane for concentration, desalting, and buffer exchange of biological samples. This product has a molecular weight cutoff (MWCO) of 100K and can be used for processing sample volumes ranging from 2 to 6 mL.

Features of Pierce Protein Concentrators PES:

• 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

For easy identification, the MWCO value is etched on the side of each device. To assist with sample addition and recovery, a clear window with graduations is located on the side of each device enabling visual determination of the retentate volume. The vertical design of the membrane allows high flux rates, low nonspecific binding, and negligible protein aggregation on the membrane; and it offers reliable and consistent results.

Pierce Protein Concentrators PES contain a membrane rated for retaining molecules with a molecular weight at least 2-fold greater than the MWCO rating of the PES membrane within the device. Reduced recovery may occur when using a concentrator with molecules smaller than the recommended mass. Protein recovery will vary depending on the specific protein in the sample and its starting concentration. To achieve >90% recovery of protein, the minimum protein sample concentration should be 0.1 mg/mL.
