Vacuum evaporator RE-LA-50

rotarylaboratoryfor sample concentration

Product overview
RE-LA Series rotary evaporator is designed for large-capacity and large-diameter evaporation flasks, increasing evaporation area and efficiency. It features a vacuum stainless-steel water bath (oil bath optional) with rotating-edge heating to improve solution evaporation and diffusion. The system is suitable for biological, pharmaceutical, chemical and food laboratories as well as small-scale production. The RE-LA-50 (50 L) model is especially suitable for heavy oil extraction.

Features

• Optional explosion-proof configuration
• PTFE and fluorine rubber dual rotating seal (patented) for high vacuum integrity
• Imported frequency-conversion motor control and digital temperature control for accurate operation
• Vacuum switching valve for continuous collection without interrupting vacuum distillation
• Electric lift for water/oil bath; manual lift support available
• PTFE discharge valve — corrosion resistant and contamination-free
• Optional spare glassware set
