  • Page 26: Setting Up And Filling The Heating Bath

    5 | Installation BÜCHI Labortechnik AG Setting up and filling the heating bath Locate the heating bath (1) in the L-shaped cut-out in the Rotavapor base (2). IMPORTANT Risk of heating bath corrosion due to use of unsuitable heating fluid Do not use pure distilled water or de-ionised water.

  • Page 27: Operation

    BÜCHI Labortechnik AG Operation | 6 Operation Preparations 6.1.1 Preparing the heating bath CAUTION Risk of skin burns from hot fluids and surfaces Do not put your hands in the hot fluid. Do not carry, shift, tip or otherwise move the heating bath when it is filled with hot fluid.

  • Page 28: Fitting The Evaporating Flask

    6 | Operation BÜCHI Labortechnik AG 6.1.2 Fitting the evaporating flask IMPORTANT Risk of evaporating flask damage if fitted incorrectly When fitting the evaporating flask make sure that the edge of the glass does not strike the vapor duct. Tighten combi-clip no more than hand-tight. Carefully fit evaporating flask (3) onto the vapor duct (2).
  • Page 29 BÜCHI Labortechnik AG Operation | 6 Switch off the Rotavapor on the heating bath. Hold the condenser (1) firmly with one hand and release the lever (2) with the other hand. Adjust the immersion angle. Lock the rotary drive unit in position again with the lever (2). Make sure that there is at least 10 mm clearance between the edge of the heating bath and the evaporating flask or vapor duct.

  • Page 30: Fitting The Receiving Flask

    6 | Operation BÜCHI Labortechnik AG 6.1.4 Fitting the receiving flask Materials required: — Grease Glisseal 40 blue (order number 048197) Apply a thin coat of Grease Glisseal 40 blue to the glass stopcock (1).

  • Page 32: Performing Distillation

    6 | Operation BÜCHI Labortechnik AG Performing distillation DANGER Risk of poisoning from inhalation of hazardous vapors Do not inhale any vapors produced during distillation. Ensure that vapors are removed immediately by a suitable fume hood. Only use the device in well ventilated areas. If vapors escape from joints or connections, check the seals concerned and re- place them if necessary.

  • Page 33: Raising And Lowering The Evaporating Flask

    BÜCHI Labortechnik AG Operation | 6 Immerse the evaporating flask in the heating bath (see Chapter 6.2.1 "Raising and lowering the evaporating flask", page 33). Wait 1 – 2 minutes to make sure distillation starts. If necessary, adjust the vacuum and/or the heater temperature see Chapter 6.2.3 "Optimization distillation", page 35.

  • Page 34: Adjusting Distillation Conditions

    To achieve optimum distillation, all devices in the system should be matched to one another. Therefore, we recommend that the Rotavapor® R-100 is used together with the BUCHI Vacuum Pump V-100 and the BUCHI Recirculating Chiller F-105 (see Chapter 3.2.4 "Typical application", page 14). That will enable achievement of a sta- ble vacuum and stable cooling, and thus a more efficient distillation process.

  • Page 35: Optimization Distillation

    BÜCHI Labortechnik AG Operation | 6 6.2.3 Optimization distillation Depending on the solvent involved, it may also be possible to further optimize the dis- tillation process. The distillation should always be set up so that the condensate does not cover more than three quarters of the coil in the condenser. There should be no condensate visible in the top quarter.

  • Page 36: Feeding Solvent During Distillation

    6 | Operation BÜCHI Labortechnik AG In applications where no vacuum is applied, lower the temperature of the heating bath. That will cause less solvent to evaporate. 6.2.4 Feeding solvent during distillation Precondition: R An external vacuum pump is connected and running. R A feed tubing leading from the glass stopcock to the evaporating flask is fitted.
