Vacuum evaporator RE-LA-20

rotarylaboratoryfor liquids

Product overview
20 L rotary evaporator RE-LA-20 manufactured in China, suitable for hemp oil extraction. Available with a heating water bath (oil bath optional) and in capacities from 5 to 50 L. The RE-LA series large-capacity rotary evaporators feature a large-diameter evaporation flask and increased evaporation area for efficient distillation in small-scale biological, pharmaceutical, chemical and food applications.

Application & system composition
Designed to integrate with supporting equipment such as recycled-water multi-use vacuum pumps, diaphragm pumps, low-temperature cycle (vacuum) pumps, circulating coolers, constant-temperature circulators and low-temperature cooling liquid circulating pumps. The 20 L model is specifically recommended for hemp oil extraction.

Features

• Optional explosion-proof device available.
• Patented dual rotating seal of PTFE and fluorine rubber to ensure high vacuum performance.
• Imported advanced frequency control system and precise, reliable temperature control.
• Vacuum switching valve enables continuous collection without breaking system vacuum.
• Water bath (oil bath optional) with electric and manual lifting support for easy operation.
• PTFE discharge valve for corrosion resistance and contamination-free discharge.
• Optional additional set of glassware available.
