Oil Bath 2.2L Stainless Steel Overview
The Oil Bath 2.2L Stainless Steel (model BOS200) is a synthetic-chemistry heating bath from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. This bath in the Baths category holds roughly 2.2 liters and maintains temperatures across room temperature +5°C to 250°C with PID control.
Stainless-steel construction throughout the reservoir gives the unit strong thermal stability for reactions requiring steady, even heat. A 425 W stainless-steel tube heater drives the bath, while a Pt100Ω sensor and PID loop hold ±0.3°C accuracy at 200°C with stirring. Digital ▲▼ keys set temperature in 1°C units.
Internal dimensions measure φ170 × 140 mm, and the chromium-free electrogalvanized steel exterior carries a baked finish. Powered at 115V (BOS200) or 220V (BOS210), the unit ships at 12 lbs from USA inventory. Manufactured in Japan, the bath is backed by Yamato's ISO 9001:2015 and ISO 14001:2015 certified quality systems.
Key Features
- PID temperature control: Holds ±0.3°C accuracy at 200°C with stirring, using a Pt100Ω sensor for repeatable setpoints.
- Operating range: Room temperature +5°C to 250°C, with a 0 to 260°C setting range for synthetic experiments.
- Stainless-steel bath: 2.2 L stainless reservoir paired with a 425 W stainless-steel tube heater for even, stable heat.
- Layered safety system: Self-diagnostic sensor-error detection, automatic overheat prevention, an independent overheat device, a heater guard, and a 6.3A fuse with short-circuit and overcurrent protection.
- Digital operation: Fixed-temperature mode, calibration offset, auto resume, and LED brightness setting via ▲▼ keys in 1°C units.
- Stirrer integration: Base indent seats a magnetic-stirrer hot plate compatible with MFD800 and MFH800 units.
How to Choose the Right Oil Bath
Selecting an oil bath comes down to matching reservoir size, temperature performance, and site power to your reaction workflow. Use these axes to confirm fit before purchase.
- Capacity: A 2.2 L reservoir with φ170 × 140 mm internal dimensions suits round-bottom flasks and small synthetic setups; size the bath to your vessel and immersion depth.
- Temperature range: Operating coverage of room temperature +5°C to 250°C determines which reactions and reflux conditions the bath can support.
- Control type: PID control with ±0.3°C accuracy at 200°C matters when reactions are sensitive to drift; digital setpoints in 1°C units aid reproducibility.
- Voltage: Match the unit to your circuit — BOS200 runs on 115V, BOS210 on 220V.
- Safety: Independent overheat prevention, sensor-error self-diagnostics, and a fused short-circuit cutout protect both samples and personnel during extended heating.
- Stirring needs: Confirm whether you require integrated magnetic stirring; the base seats compatible MFD800 or MFH800 hot-plate stirrers.

Frequently Asked Questions
What is the operating temperature range of the BOS200 oil bath?
The bath operates from room temperature +5°C up to 250°C, with a setting range of 0 to 260°C. PID control holds ±0.3°C accuracy at 200°C when stirring.
What is the reservoir capacity and internal size?
The stainless-steel reservoir holds approximately 2.2 liters. Internal dimensions measure φ170 × 140 mm, sized for small synthetic-chemistry vessels.
What is the difference between the BOS200 and BOS210?
Voltage is the only difference: BOS200 runs on 115V and BOS210 runs on 220V. Capacity, materials, temperature range, and control system are identical, so choose the model that matches your circuit.
What material is the oil bath made from?
The bath and reservoir are stainless steel for thermal stability. The exterior is chromium-free electrogalvanized steel with a baked finish, and the heater is a 425 W stainless-steel tube type.
What safety features protect against overheating?
The unit includes self-diagnostic sensor-error detection, automatic overheat prevention, and an independent overheat prevention device. A heater guard and a 6.3A fuse with short-circuit and overcurrent protection add further coverage.
Can the oil bath be used with a magnetic stirrer?
Yes. The base indent seats a magnetic-stirrer hot plate compatible with Yamato MFD800 and MFH800 units, allowing integrated stirring during heating.
