A rotary vacuum controller regulates and displays system vacuum, enabling stable, repeatable conditions for solvent evaporation and vacuum distillation. ROVA101 is built for integration with laboratory rotary evaporators and other vacuum-driven solvent removal systems.

ROVA101 is a compact COLO.Science digital vacuum controller featuring a large 5″ TFT touch display, dual operation modes (single-point and programmable multi-segment control), corrosion-resistant wetted materials (PTFE, PP, silicone, ceramic), and direct pump power control for optimized energy usage and vacuum stability.
