    6 Operation Operation This chapter explains the operating elements and possible operating modes. It gives instructions on how to operate the Multivapor properly and safely. Settings at the Multivapor platform Variable parameters of the instrument are the temperature and rotational speed of the horizontal movement of the heating plate.

  • Page 47: Selecting A Preset Temperature

    The rotational speed of the moving platform ranges from 0 to 370 rpm for the Multivapor P-6 and from 0 to 485 rpm for the Multivapor P-12. Within this range even fairly viscous samples are thoroughly agitated by strong vortex action.

  • Page 48: Sample Preparation

    6 Operation Sample preparation 6.2.1 Heating up the instrument Distilled water is added to each glass cylinder on the crystal rack to transfer the heat from the heating plate to the sample tube. Equal amounts of water must be added to each cylinder to provide a uniform heat transfer.
  • Page 49 6 Operation • Screw the adapter onto the tube. • Place the sample tube into the transfer plate. Make sure that it snaps in place. • Occupy all positions or use the blank • Transfer the whole assembly at once into the adapters instead (optional).
