Thermo Scientific™ Pierce™ Protein Concentrator PES

Description

• The Thermo Scientific™ Pierce™ concentrators are easy-to-use centrifugal devices that provide fast processing and excellent recovery of protein samples
• These disposable ultrafiltration devices contain a polyethersulfone (PES) membrane for the concentration, desalting, and buffer exchange of biological samples, such as tissue culture media, antiserum, monoclonal antibody preparations, and chromatography fractions
• They can also be used to remove unincorporated label following protein modification reactions
• The PES membrane in these devices is available in five distinct molecular-weight cutoffs (MWCO) of 3K, 5K, 10K, 30K, and 100K, and can be used for processing sample volumes from 100 μL to 100 mL
• The MWCOs are etched on the sides of the concentrators for easy identification, while a clear window with graduations on the side of each device allows for visual determination of the concentrated sample (retentate) volume
• The unique design provides reliable and consistent results
• Multiple device sizes are available to handle maximum sample volumes of 0.5 mL, 6 mL, 20 mL, and 100 mL
• Rapid processing—unique design minimizes membrane fouling and sample concentration of 10- to 30-fold can be achieved in 5–30 minutes for 10K MWCO (device dependent—times may vary for other MWCO’s), even with particle laden solutions
• High recovery—retain >90% of protein samples while removing contaminants or exchanging buffers
• Convenient—clear markings, wide sample chamber and removable filtrate chamber make handling simple and easy
• Instrument compatible—can be used with standard centrifuges utilizing either fixed-angle or swinging-bucket rotors.
