ROVA450 — 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.
ROVA450 is a compact laboratory unit with intelligent PID temperature control and an easy-to-read digital display for heating temperature, rotation speed and timing. The heating range covers RT+5 °C to 180 °C (oil mode), while rotation is adjustable from 20–320 rpm. A vertical condenser with 1600 cm² cooling surface provides efficient condensation, and the manual lift ensures precise handling (with lift integration for safe handling in case of power failure).
