Buchi Rotavapor (R-210) with Buchi Heating Bath (B-490) and Vacuum Controller (V-850) (Refurbished)

The BÜCHI Rotavapor R-210 is a high-performance rotary evaporator designed for precise, efficient, and reproducible solvent distillation, concentration, and purification. This advanced system is widely used in pharmaceutical, chemical, and research laboratories for applications such as solvent evaporation, sample drying, recrystallization, and Soxhlet extractions. The R-210 features a digital display, enabling users to monitor rotation speed and vapor temperature for optimal control.

Paired with the B-491 Heating Bath, this system offers precise temperature control up to 180°C, accommodating both water and oil-based heating methods for enhanced versatility. The V-850 Vacuum Controller ensures automated vacuum regulation, minimizing solvent bumping while maximizing evaporation efficiency. This combination of automated control, digital monitoring, and seamless vacuum integration makes the R-210 system an essential tool for high-precision laboratory workflows.
