Description

The NexGen 50L comes standard with vertical glassware and digital temperature/rotation control, while its bath volume allows for rapid heat-up temp. The condenser units have specially designed glass tubes that utilize surface area extremely efficient.

Rotary evaporator features a specially designed motor and belt drive unit, which provides constant rotation at speeds from 10 to 180 rpm with quite operations. As the flask containing the solvent is rotated, it continually transfers a thin layer of liquid over the entire inner surface. This gives a very large surface area for evaporation, which is caused by the gentle heating from the water bath. The rotating system is fitted with a special seal that allows the apparatus to be placed under vacuum, effectively reducing the boiling point of the solvents and removing the vapor, making the process more efficient. Each unit is also equipped with an easy-to-use vacuum release and a continuous feed system, which allows solvent to be constantly drawn into the rotating flask without needing to stop the operation.

Digital water bath operates from ambient temperature to 99°C (210°F) with PID temperature control stepping at 0.1°C increments. Heating coils are located directly inside the pan for the most efficient heating possible with rubber lined rotating flask bucket to maintain temperature throughout.

Standard Glassware Set includes a single 50 liter rotating evaporating flask, two separate 20 liter receiving flasks, and three vertical condensers. Rotary evaporators with vertical glass condenser are great for distillation of solvents with higher boiling points whilst under vacuum.

Your safety is important to us! Please use caution when operating. Users of glass reaction equipment must take all necessary precautions to avoid contact with rotating parts, particularly entanglement of loose clothing, hair, necklaces, or other jewelry. Under these circumstances, the winding action of the rotating parts can draw the user(s) into the apparatus, resulting in breakage of glassware, burns, and/or chemical exposure. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
