Rotary Evaporators

A rotary evaporator is composed of an electric motor that causes the rotation of a tube attached to a ground glass joint guide tube. The latter has a round-bottomed flask containing the solution attached to its structure. Maintaining a rotating motion, this flask is partially immersed in water. The system contains a refrigerant that circulates a liquid (water or antifreeze), this generates the condensation of the solvent, which is recovered in a collector. Its components include:
 
  • A round flask to collect the distilled material.
  • A vacuum equipment to reduce the internal pressure of the equipment.
  • A height-adjustable column and a spiral condensation column.
  • An adjustable heating unit.
  • A second round flask for evaporation.
  • A pedestal for the rotation motor.

Rotavapor Assembly

A rotary evaporator is composed of an electric motor that causes the rotation of a tube attached to a ground glass joint guide tube. The latter has a round-bottomed flask containing the solution attached to its structure. Maintaining a rotating motion, this flask is partially immersed in water. The system contains a refrigerant that circulates a liquid (water or antifreeze), this generates the condensation of the solvent, which is recovered in a collector. Its components include:

  • A round flask to collect the distilled material.
  • A vacuum equipment to reduce the internal pressure of the equipment.
  • A height-adjustable column and a spiral condensation column.
  • An adjustable heating unit.
