Properly conditioned tubes are essential for performing thermal desorption analyses, so it is important to have an ample supply of tubes on hand. The GERSTEL Tube Conditioner (TC) allows simultaneous conditioning of up to 10 TDS or TDU tubes and up to 50 Twister stir bars. The TC is a stand-alone system and therefore provides the means to condition tubes without interfering with sample analysis. In the conditioning process, the TDS tubes are heated in the TC with a fixed flow of ~100 mL/min of inert gas. After conditioning, the tubes can be quickly cooled outside of the TC without interruption of gas flow. The unique pneumatics system does not require all 10 positions to be filled, and can condition a mix of adsorbent packed or empty tubes simultaneously. The same design principles used in the TDS were used for the TC, therefore, the TC provides highly accurate temperature and gas flows as well as a contaminant free gas stream.

Main Features and Advantages

  • Conditions tubes off-line so TDS and TDU are always available for analysis
  • Accurate temperature and flow provide optimum conditioning
  • One instrument conditions TDS and TDU tubes and well as Twisters
