Thermo Scientific Pierce concentrators are disposable ultrafiltration centrifugal devices with a polyethersulfone (PES) membrane for the concentration, desalting and buffer exchange of biological samples. These products are available in four sizes (0.5 mL, 6 mL, 20 mL and 100 mL) and with a range of molecular-weight cutoffs (3K, 5K 10K, 30K, 50K, and/or 100K MWCO).
- Rapid processing—concentrate samples up to 10- to 30-fold in 5–30 minutes for 10K MWCO (device dependent—times may vary for other MWCO’s)
- 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
