Working Principle

    The evaporation flask rotates continuously at speeds up to 280 rpm via a powerful rotation motor, increasing the sample surface area to accelerate evaporation under controlled vacuum conditions. The flask connects to the vapour tube via a coupling ring with a standard NS 29/32 joint, while PTFE sleeves maintain a tight seal preventing glass-to-glass sticking. The heating bath accommodates both water and oil as bath fluids, reaching up to 85°C with water and 185°C with oil. Vapour generated passes through one of four available condenser types for collection in the receiving flask. Up to nine programmable distillation steps can be configured, with automatic programme termination upon reaching the set time.

    Key Features

     
    Rotation speed: up to 280 rpm; adjustable evaporation flask angle
    Heating bath: up to 85°C (water) and 185°C (oil)
    Up to 9 programmable distillation steps; automatic timing shutdown
    Four condenser types; standard 1,000 mL evaporating and receiving flasks
    PTFE-coated inner bath; anti-corrosion and chemical resistant
    Electric lifting device with automatic power-outage flask removal
    Touchscreen display: bath temperature, rotation speed, vacuum and condenser temperature
    Vacuum controller, vapour temperature sensor and vacuum pump available as optional accessories

     

    An electric lifting device with adjustable stroke enables precise flask positioning and automatically removes the flask from the heating bath during power outages, protecting samples from thermal damage. Overheating and dry-running protection are standard safety features. The anti-corrosion PTFE-coated inner bath and high-quality protective shell prevent scalding and chemical degradation during routine use.
