For automated 24-h distillation


Large-scale evaporator designed for unattended use. The required solvent is automatically refilled and condensate continuously drained off. The automatic water bath refill system along with an additional control panel for filling and electronics allows for use over an extended period of time.

  • Designed for 24-h continuous use
  • For continuius operation overnight and at the weekend
  • Affordable alternative to common 50 and 100-liter evaporators
  • Particularly suitable for solvent processing
  • Reduced exposure to solvent vapor and spills



Laborota 20 automatic Large scale evaporator

Every automatic evaporator consists of these components:

  • Your choice of an LR 20 model with integrated vacuum sensor and vacuum valve. Automated distillation with constant pressure P(const) or with vapor temperature control T(auto)
  • 4-head vacuum pump, chemically resistant, rated at 3 m³/h, final pressure 9 mbar, 350 W connection power. Vacuum pump comes with separator and exhaust waste vapor condenser is integrated into system
  • Additional operating panel for LR 20 control automatic specific flask refill settings

 

Automatic product charging:

  • Drive head features weight sensor which is responsible for refilling the evaporating flask according to the amount of solvent distilled off
  • Adjustable max. and min. filling level of evaporating flask
  • Charging of product controlled via solenoid valve with the help of the systems vacuum and end fill sensor that indicates solution evaporation is complete

 

Automatic discharge of condensate:

  • The discharge from the vacuum system works in a quasi-continuous way. Several times per minute the processor-controlled valve matrix releases a small volume of condensate

 

End of distillation:

  • Termination with the built-in timer
  • After reaching an adjustable end pressure (only with T(auto))
  • Terminating the distillation by operator
