Introduction Of 50L Rotary Evaporator

R-1050 rotary evaporator, the capacity of the evaporating bottle is 50L, and the capacity of the receiving bottle is 20L. The 50L rotary evaporator adopts a large-capacity, large-diameter rotary evaporator to increase the evaporation area. It is placed in a water bath under reduced pressure and heated by rotation to make the solution diffuse and evaporate efficiently in the evaporator. It is widely used in the scale concentration of samples. Drying, extraction, recycling and other experiments. It is an ideal device for mass production in chemical industry, pharmaceutical industry, food industry, environmental protection industry, colleges and universities, scientific research laboratories and industrial and mining units.

Applications Of 50L Rotary Evaporator

50L rotary evaporator is widely used in large-scale concentration, drying, extraction, recovery and other experiments of samples. It is an ideal equipment for mass production in chemical industry, pharmaceutical industry, food industry, environmental protection industry, colleges and universities, scientific research laboratories and industrial and mining units.

Operating Procedures

(1) Preparation

  1. Turn on the power to the cryopump (cycle first, then refrigeration).
  2. Turn on the vacuum pump and start vacuuming.

(2) Feeding

  1. Feeding method: first pump the rotary evaporator into a negative pressure state, and connect the feeding valve with the sample to be added with a hose;

Open the feeding valve valve, the sample will be directly pumped into the rotary bottle, close the feeding valve valve after feeding

(3) Operation

  1. Start the 50L rotary evaporator
  2. Adjust the heating bath to the proper height
  3. Pour water into the bath and submerge it to 1/2 of the rotary bottle without overflowing.
  4. When the rotation indicator light is on, turn the speed control knob to adjust the motor speed.
  5. Bath heating: After setting to the desired temperature, turn on the heating.

(4) Feeding

  1. Directly open the exhaust valve on the recovery bottle to reduce the pressure in the recovery bottle, and then open the discharge valve to discharge the material.

(5) Shutdown

  1. Stop spinning.
  2. Open the fill tube cock to relieve internal vacuum.
  3. Turn off the pressure relief device.
  4. Turn off the cooling water circulation device and water bath device.
  5. Disassembly.
