ROT-X-TRACT-LC Corning Accelerated One-Step Liquid-Liquid Extractors

Not yet rated

The ROT-X-TRACT-LC® is designed to accommodate up to eight Corning Accelerated One-Step apparatuses (glassware sold separately). The Corning Accelerated One-Step extraction apparatus combines continuous liquid-liquid extraction and concentration into one step. A Freidrichs condenser is used to reduce overall height to accommodate traditional laboratory hood specifications; however Allihn condensers can be substituted per request.

A hydrophobic membrane allows the organic solvent to circulate through the 1 liter sample bottle continuously until the extraction is complete. By incorporating a stop-cock assembly and 3-ball Snyder column, the Corning One-Step extractor can both extract desired analytes as well as evaporate solvent from the end by-product within the same cycle.

The Corning One-Step extractor comes with an electronic side control box which enables the operator to program specific bath temperatures and time cycles to stay in compliance with the designated methodologies.


  • Multiple simultaneous extractions: extract and concentrate up to eight samples simultaneously
  • Precise controls: digital timer and heat controls
