Pierce™ Protein Concentrators PES, Thermo Scientific
Concentrators
Protein Concentrators PES are disposable ultrafiltration centrifugal devices with a polyethersulfone (PES) membrane for concentration, desalting, and buffer exchange of biological samples.

  • Molecular weight cutoff
  • Can be used for processing sample volumes
  • Rapid protein concentration
  • Excellent protein recovery
  • Versatile sample concentrations, diafiltrations, or buffer-exchange of biological samples
  • Reliable, consistent results

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) and can be used for processing various sample volumes. Protein Concentrators 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 twofold 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 greater than 90% recovery of protein, the minimum protein sample concentration should be 0.1 mg/mL.
