ETL-certified to meet UL/CSA requirements. Most municipalities require this certification, which also ensures higher safety standards and longer equipment lifespan.
All ELAB rotovaps come with PTFE valves to ensure solvent resistance. Rapid heat-up is made possible by its optimized bath volume. Glass tubes used in the condenser unit have been designed to optimize surface area, thereby increasing evaporation efficiency. A rotary evaporator features a motor and worm gear designed for constant rotation at speeds up to 130 rpm. A thin layer of liquid is constantly transferred over the entire inner surface of the flask containing the solvent. The water bath gently heats the surface, creating a large area for evaporation. Special seals on the rotating system enable it to be placed under vacuum, which reduces the boiling point of the solvents and removes the vapor phase, thereby increasing efficiency. Moreover, each unit is equipped with a vacuum release that is easy to use, which allows continuous feed. The digital water bath operates from ambient temperature to 99C (210F) with 0.1C step-by-step temperature control. Should the controller fail, the overheat protector will shut down the power. Standard Glassware Set contains a 10L round-bottomed evaporating flask, a 5L round-bottomed receiving flask, and a vertical condenser. Distilling solvents with higher boiling points is made easier by rotary evaporators with vertical glass condensers.
