Oil Bath Digital 5L Overview
The Oil Bath Digital 5L (model BO302A) from Yamato Scientific is a 5 L constant-temperature oil bath engineered for an operating range of ambient +10°C to 180°C. LabSupplies.com, an authorized dealer, supplies the genuine unit with PID temperature control, white LED digital readout, and a flat-shaped reservoir built for fast cleaning.
A φ240 mm flat-bottom design keeps the heater and sensor outside the bath, simplifying fluid changes and routine maintenance. Stainless steel forms the reservoir, while a PBT fiberglass-reinforced exterior handles heat and splash. Heating comes from a 1000 W aluminum-sheathed element, and a Pt100Ω sensor drives the control loop to ±2.0°C accuracy.
Two voltage builds cover global benches: BO302A runs 100-115V and BO312A runs 200-230V. Each unit measures φ262 (max. D286) × H240 mm and ships at 16 lbs. Manufactured in Switzerland, the bath carries ISO 9001:2015 and ISO 14001:2015 certification, and it pairs with Yamato RE202A/212A and REV202MA/212MA rotary evaporators.

- Digital control: white LED display, key entry, 1°C minimum digit, with overshoot alert, selectable auto resume, and calibration offset.
- Safety package: automatic and independent overheat prevention, temperature upper-limit error detection, and an overcurrent protection fuse.
- Voltage options: BO302A (100-115V) and BO312A (200-230V), each with a 2A service outlet.
How to Choose the Right Oil Bath
Matching an oil bath to your workflow means balancing reservoir size, working temperature, and the power available at your bench. Use these axes to confirm the unit fits your application and your site infrastructure.
- Capacity: a 5 L reservoir suits larger flasks and multi-vessel heating; verify your vessel volume and footprint before ordering.
- Temperature range: this model reaches ambient +10°C to 180°C, so confirm your fluid and process stay within that window.
- Control type: PID control with a digital LED display delivers stable setpoints and ±2.0°C accuracy for repeatable runs.
- Voltage: select BO302A for 100-115V circuits or BO312A for 200-230V circuits to match your facility power.
- Footprint: the φ262 (max. D286) × H240 mm body must clear adjacent equipment and fume hood space.
- Safety features: overheat prevention, upper-limit error detection, and overcurrent protection matter when running unattended.

Frequently Asked Questions
What is the operating temperature range of the BO302A oil bath?
The BO302A operates from ambient +10°C to 180°C. A Pt100Ω sensor and PID control hold the setpoint to ±2.0°C accuracy, with a white LED digital display showing temperature to a 1°C minimum digit.
What is the reservoir capacity and footprint?
The bath provides a roughly 5 L stainless steel reservoir with a φ240 mm internal diameter. External dimensions are φ262 (max. D286) × H240 mm, and the unit ships at 16 lbs.
What is the difference between the BO302A and BO312A?
Voltage is the only difference. BO302A runs on 100-115V and BO312A runs on 200-230V. Both share the same 5 L reservoir, 180°C maximum temperature, PID control, and 1000 W heater.
How much power does the heater draw?
The unit uses a 1000 W aluminum-sheathed heater. It also includes a 2A service outlet and an overcurrent protection fuse for safe operation.
What materials are used in the bath construction?
The reservoir is stainless steel, and the exterior uses PBT fiberglass-reinforced resin with chromium-free electrogalvanized steel and aluminum. Glass wool serves as the heat insulator, and the flat-shaped design keeps the heater and sensor outside the bath for easy cleaning.
Is the BO302A compatible with Yamato rotary evaporators?
Yes. The oil bath is compatible with Yamato RE202A/212A and REV202MA/212MA rotary evaporators, making it a direct fit for distillation and concentration workflows.
