Dialysis Systems

Dialysis techniques are reliable and cost effective methods for concentrating samples.  G-Biosciences created novel dialysis tools which allow for the concentration of samples with zero sample loss.  Tube-O-CONCENTRATOR™ is a versatile concentration tool which utilizes a novel, water-absorbing, liquid polymer and the patented Tube-O-DIALYZER™​ for rapid concentration of dilute sample solutions with zero analyte loss.  The Tube-O-CONCENTRATOR™ and Tube-O-DIALYZER™​ systems are designed for centrifugation.  The Tube-O-REACTOR™ is a system that allows key steps of cross-linking, coupling, and modification of proteins and/or nucleic acids for be performed in a single tube.  This tool minimizes the risk of sample loss and reduces expiremental time and hands-on steps.
