Tube-O-CONCENTRATOR is a versatile concentration device that utilizes a novel, water absorbing, liquid polymer and our patented Tube-O-DIALYZER for the rapid concentration of dilute protein solutions with zero protein loss.  The unique tube design of Tube-O-DIALYZER ensures that 100% sample is recovered; simple place the entire device in a bench top centrifuge and spin for a few seconds.


The Tube-O-CONCENTRATOR solution is a liquid polymer that rapidly absorbs water through the dialysis membrane in the Tube-O-DIALYZER cap, which retains all molecules with a molecular weight >1kDa. 
Tube-O-CONCENTRATOR is available in two sizes for concentrating sample volumes of up to 250µl (Micro) (Cat. # 786-625) or 2.5ml (Medi) (Cat. # 786-626).



  • Rapid concentration of protein solutions without protein precipitation
  • Combination of a unique tube format dialysis device and a water absorbing liquid polymer
  • Suitable for up to 250µl or 2.5ml protein solutions
  • Zero protein loss, even if protein precipitation occurs



  • For the concentration of dilute protein solutions
