About this machine

This Büchi R-50 E is a used laboratory rotary evaporator — also commonly referred to as a rotovap — located in Barneveld, Netherlands. Rotary evaporators are widely used in laboratory settings for the gentle and efficient removal of solvents from samples through evaporation under reduced pressure combined with rotation. Büchi is a well-established Swiss manufacturer with a long-standing reputation for laboratory and process equipment, particularly in the fields of evaporation, extraction, filtration, and spray drying, serving research, pharmaceutical, chemical, and food science industries.

This unit is a large-scale, floor-standing rotary evaporator with a working volume of 50 litres, mounted on a wheeled frame that allows for repositioning within a facility. The frame occupies a footprint of 1.50 x 0.85 metres and stands 2.50 metres in total height, making it a substantial piece of laboratory infrastructure. The machine carries ATEX certification, indicating it is suitable for use in potentially explosive atmospheres — an important consideration for solvent-handling environments.

The evaporator is supplied with two 50-litre glass evaporation flasks, providing redundancy or flexibility for different applications. Evaporation is facilitated by a glass cooling condenser with a heat exchange surface area of 1.6 m², and the system includes various additional glass components. The bath features manual hydraulic lifting, allowing the operator to raise and lower the flask into the heating bath with controlled precision. Operating temperature ranges from 40 °C to 75 °C, and the rotation speed is adjustable between 5 and 100 rpm. The drive motor operates at 240 watts and the unit runs on a 380-volt supply.

The machine is offered in used condition and is ready for inspection at its location in Barneveld, Netherlands.
