The unique design of Thermo Scientific™ Pierce concentrators provides a highly effective and efficient solution for concentrating your protein without losing sample.

Our 0.5 mL capacity concentrators are available with a polyethersulfone (PES) membrane, and the 7 mL and 20 mL devices come with a regenerated cellulose membrane. We offer a variety of molecular weight cutoff (MWCO) membranes for most applications.

  • Rapid concentration—unique cone and vertical designs minimize membrane fouling and provide high-speed concentrations, even with particle-laden solutions
  • Excellent recovery—remove buffer and small molecules while retaining >90% of protein samples
  • Convenient—3 sizes designed to fit microtubes, 15 mL, and 50 mL conical tubes; ideal for simple concentration of 100 μL to 20 mL of sample
  • Compatible—use a standard microfuge (0.5 mL) with fixed-angle rotors or swinging-bucket centrifuges; collect and recover samples without inverted spinning
