The Genevac Flip-Flop system is an innovative tool designed to facilitate post ASE® concentration and preparation of samples. Samples are collected in the special Flip-Flop tube, the funnel and vial are fitted, the tube flipped over and second cap removed.
Your ASE sample can now be concentrated directly into a GC autosampler vial using a Genevac ROCKET Evaporator. The Genevac ROCKET Evaporator enables rapid concentration or evaporation of up to 18 Dionex ASE® vials simultaneously. Using this simple procedure eliminates manual transfer steps and helps automate the ASE® sample concentration / preparation process resulting in improved laboratory workflow, increased reproducibility of results and enhanced sample recovery.
