Rotary Evaporator


⇒ The apparatus consists of an evaporating flask rotated by heavy duty motor in a heating water bath. 

⇒ Fitted with speed regulator for minor speed adjustments. 

⇒ Vacuum distillation of solvent at high and low temperature is achieved quickly and efficiently by use of a heavy duty motor, which prevents foaming and bumping of the liquid (solvent) into the evaporating flask and also distillation under controlled atmosphere. 

⇒ The evaporating flask is pear shaped to give a large surface area of evaporation. 

⇒ Evaporating flask is clamped to a glass duct which goes through the drive unit and protrudes about 120m.m. into the condenser. 

⇒ Condenser is fitted with standard joint at the top and the bottom for receiver flask. 

⇒ Unit is fitted with a quick action jack.

Rotary Evaporator mainly used in pharmaceutical, chemical and biopharmaceutical industries concentrated, crystallization, drying, separation and dissolved coal recovery.

The Principle: Under a vacuum condition and constant temperature heating, make rotating bottle constant speed rotation, the material in the sidewall formation of large area thin film, efficient evaporation, The dissolved coal steam through efficient glass condenser cooling , recycling collection bottle, greatly improve the efficiency of evaporation.

  • Host  part:  using foreign  advanced  drive  system,  reasonable  structure,  durable, practical.
  • Control temperature parts: foreign advanced frequency control system, temperature control system to ensure accurate performance.
  • Water bath: imports of stainless steel plate stamping, vertical automatic lift.
  • Seal member: choice the latest foreign PTFE material, special technology processing, enhanced sealing, corrosion resistance and abrasion resistance.
  • The main structure: high quality aluminum alloy and stainless steel, the more perfect and improve the instrument reasonable performance.
