ROCKFORD, Ill. (August 8, 2011) – Thermo Fisher Scientific, the world leader in serving science, today introduced the Thermo Scientific Pierce Concentrators, PES for concentrating, desalting or exchanging buffers of small-volume biological samples, including proteins and nucleic acids.

The concentrators contain a vertical polyethersulfone (PES) membrane for the centrifugal processing of sample volumes between 100 to 500 microliters. This unique design allows for 10- to 30-fold sample concentration in 10 minutes, with greater than 90 percent recoveries.

The disposable Pierce® Concentrators, PES are available in four distinct molecular-weight cutoffs (MWCOs) of 3K, 10K, 30K and 100K. The MWCOs are etched on the sides of the concentrators for easy identification, while a clear window with graduations marked on the side of each device allows for visual determination of the retentate volume. The concentrators are compatible with most bench-top microcentrifuges with fixed-angle rotors that accommodate 2.2 milliliter tubes. The Pierce Concentrators, PES are available in packs of 25.
