Applications
The Buchi B-461 is the dedicated water bath component for Buchi rotary evaporators (RotoVapors), providing stable, controlled heating of the solvent flask during evaporation. It is also commonly used as a standalone benchtop water bath for general laboratory heating tasks such as sample incubation, reagent warming, and reactions requiring precise temperature control up to 100°C. The B-461 pairs directly with Buchi rotary evaporator systems and was a standard fixture in chemistry, pharmaceutical, and research labs from the 1980s onward. Its deep stainless steel bowl and high 1200W heating element allow it to reach and hold temperature quickly — a key requirement in rotary evaporation workflows where consistent bath temperature directly affects evaporation rate and solvent recovery. Units like this continue to see active use in teaching labs and research facilities that run Buchi rotary evaporator setups.
This Buchi B-461 heated water bath has been tested and heats up correctly — it reaches temperature as expected across its 0–100°C range. The stainless steel bath bowl shows mineral deposits and surface rust staining on the interior walls and exterior, consistent with normal lab use over time. The heating element coil and sensor fitting are intact and visible inside the bowl. The base housing and front panel controls are intact with typical cosmetic wear. Note: this unit requires a special IEC-style power cord that is not included — please refer to the photos for the power inlet type on the rear panel. Please view our photo set and contact us if you have any questions.
