Laboratory Oil Baths

Yamato Scientific oil baths provide uniform, high-temperature heating above the boiling point of water — for synthetic chemistry, reflux, rotary evaporation, and constant-temperature work from room temperature up to 270°C. LabSupplies.com is an authorized Yamato dealer offering the full range, from compact 1 L synthetic-experiment baths to a 37 L large-capacity bath, all with PID temperature control and multi-layer overheat protection.

Types of Yamato oil bath

• Economy digital (BO series) — BO-302A (5 L) and BO-601 (7 L), RT +5/+10°C to 180°C with PID control. The BO-302A is purpose-matched to Yamato RE/REV rotary evaporators.
• Synthetic-experiment baths (BOG / BOS) — 1 L and 2.2 L baths to 240–250°C with ±0.3°C control. Choose BOG glass for high visibility or BOS stainless for temperature stability; both seat a magnetic-stirrer hot plate (MFD800/MFH800) in the base.
• Large capacity (BOA-311) — a 37 L bath to 270°C with ±0.1°C accuracy, jet stirring, RS485 communication, and triple overheat protection for demanding production and QC work.

Why a Yamato oil bath

• High-temperature reach — heat well past water's 100°C limit, up to 180–270°C depending on model.
• PID precision — microprocessor control with digital setting and ±0.1°C to ±2°C accuracy by model.
• Layered safety — automatic and independent overheat prevention, temperature upper-limit error, overcurrent fuse; the BOA adds a float switch and emergency stop.
• Stirrer integration — BOG/BOS baths locate a magnetic stirrer for combined heat-and-stir reactions.
