  • Heating Bath:

Usually a water or oil bath, used to heat the vials and evaporate the solvent. Baths are usually temperature controlled and can be adjusted to the desired temperature for a particular application.

  • Spinning Flask:

This is the container for the sample to be evaporated, large volume, usually made of glass and attached to a rotating shaft. The sample is swirled in the flask to increase the surface area and aid in the evaporation process.

  • Condenser:

A component that condenses evaporated solvent back into liquid form. The condenser is usually cooled with water or another coolant to help condense the steam.

  • Vacuum system:

A vacuum pump is used to reduce the pressure in the system, which helps to speed up the evaporation process by lowering the boiling point of the solvent.

  • Control Panel:

The control panel is used to adjust the temperature of the heating bath, the speed of the spinner, and other variables such as vacuum pressure and evaporation time.

  • Glassware:

Rotary evaporators typically come with a set of glassware, including vials, condensers, and other components required for a particular application.

Operating procedures

(1) Preparation

After assembling the machine, connect the cryopump and vacuum pump according to the connection diagram of the supporting equipment;

  1. Turn on the cryopump
  2. Turn on the vacuum pump, start vacuuming, and pay attention to the reading of the vacuum gauge. When the vacuum gauge maintains the maximum vacuum for a period of time, it indicates that the equipment is well sealed and can start feeding.

(2) Feeding

  1. Feeding method: first pump the large scale rotary evaporator into a negative pressure state, connect the feeding valve with the sample to be added with a hose, open the valve of the feeding valve, and the sample will be directly pumped into the rotary bottle, after the feeding is completed Close the fill valve valve. It is recommended to add no more than one-half of the spinner bottle each time.

(3) Operating the heating bath

  1. Adjust the height of the heating bath so that the spinner bottle is placed in the water bath.

Adjustment method: manual lifting, turn the lifting wheel on the heating bath, clockwise to rise, reverse to fall.

  1. Pour pure water into the bath, submerge 1/2 of the spinner bottle, just don’t overflow.
  2. Switch on the power supply to the heating bath.
  3. Set the temperature via the temperature controller on the right side of the heating bath.

(4) Operation rotation

  1. First turn the speed control knob on the speed control box to the minimum left, then turn on the power of the rotating motor, turn it up to turn on the power switch, the indicator light is on, the display screen of the speed control box is on, and then slowly turn right to the required speed .

(5) Shutdown.

  1. First stop the heating bath;
  2. Turn off the rotary switch;
  3. Open the inlet and outlet valves to release the vacuum;
  4. Finally turn off the vacuum pump and cryopump.
  5. Disposal after downtime: When not in use for a long time, please turn off and disconnect the power supply.
