ROVA900 — Laboratory rotary evaporator (rotary vacuum evaporator)
OVERVIEW
A rotary evaporator (rotary vacuum evaporator) is a standard instrument for gentle solvent removal under reduced pressure. It is widely used in chemistry, biochemistry and pharmaceutical labs for concentration, solvent recovery and sample preparation.
ROVA900 is a laboratory unit with a large LCD display and digital control of heating temperature, rotation speed and timing. The 5 L heating bath supports temperatures up to 180 °C, while rotation is adjustable in the range 20–280 rpm. A vertical coiled condenser (1700 cm²) ensures efficient condensation, and the motorized lift provides safe, convenient operation (automatic lift-up to the top position in case of power failure).
