ROVA193 — Rotary evaporator (vacuum rotary evaporator)
OVERVIEW
A rotary evaporator is designed to rotate a flask at controlled temperature and under reduced pressure to form a thin film, enabling efficient evaporation, condensation and solvent recovery. It is widely used for concentration, crystallization, separation and recovery of heat-sensitive materials in bio-pharmaceutical, chemical, food and R&D laboratories.
ROVA193 is a compact COLO.Science rotary evaporator with an easy-to-read LCD display (temperature, rotation speed and time), a 5 L heating bath with switchable water/oil mode (up to 180 °C in oil mode) and a high-efficiency condenser (1,700 cm²) for reliable condensation. The system includes a motorized lift with quick-action and an automatic flask lift-up in case of power failure, plus a built-in timer for precise process control.
