Why order the BOS200 from LabSupplies.com
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 the USA. Manufactured in Japan, the bath is backed by Yamato's ISO 9001:2015 and ISO 14001:2015 certified quality systems.
Key Features
- 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.
- 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.
- Temperature range: Operating coverage of room temperature +5°C to 250°C determines which reactions and reflux conditions the bath can support.
- Voltage: Match the unit to your circuit — BOS200 runs on 115V, BOS210 on 220V.
- Stirring needs: Confirm whether you require integrated magnetic stirring; the base seats compatible MFD800 or MFH800 hot-plate stirrers.
