Pierce Concentrators PES - 3K, 10K, 30K, 100K MWC
Thermo Scientific Pierce Protein PES Concentrators are disposable ultrafiltration centrifugal devices with a polyethersulfone membrane for concentration, desalting and buffer exchange of small-volume protein samples.
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 0.05mg/mL.

Pierce Protein Concentrators, 9K MWCO
Thermo Scientific Pierce Protein Concentrators, 9K MWCO are disposable centrifugal devices for high-performance concentration, diafiltration or buffer-exchange of biological samples.
The high-performance regenerated cellulose membranes in these 9K molecular-weight cutoff (MWCO) units are carefully and accurately rated to provide more than 90% protein recovery for proteins larger than 9000 daltons.
Pierce Protein Concentrators, 20K MWC
Thermo Scientific Pierce Protein Concentrators, 20K are disposable centrifugal devices for high-performance concentration, diafiltration or buffer-exchange of biological samples. The regenerated cellulose membranes are accurately rated for molecular-weight cutoffs (MWCO) and routinely provide greater than 90% recovery of proteins larger than the membrane MWCO.

Pierce Protein Concentrators, 150K MWCO
Thermo Scientific Pierce Protein Concentrators, 150K are disposable centrifugal devices for high-performance concentration, diafiltration or buffer-exchange of biological samples. These centrifugal concentrators provide efficient concentration of biological samples containing proteins (antigens, antibodies and enzymes), nucleic acids (DNA) and micro organisms (viral particles).
