Water Bath Digital 7L Overview
The Yamato Scientific Water Bath Digital 7L (BM401) is a compact bench water bath delivering a 7 L working capacity across an operating range of ambient +5 to 95°C. LabSupplies.com supplies this unit as an authorized Yamato Scientific dealer. PID control by microprocessor holds ±1°C accuracy at 60°C for repeatable incubation, warming, and sample-thawing routines.
A SUS316 pipe heater rated at 1 kW drives fast warm-up, while a Pt100Ω sensor feeds precise temperature feedback. Exterior panels use chrome-free electrogalvanized carbon steel finished in a chemical-proof baked-on coating. An aluminum alloy protective reservoir cover guards against burns from accidental tank contact, and resin plates round out the chamber build.
Operating on 115V, the BM401 measures 18 × 15 × 14 inches and weighs 18 lbs, fitting tight bench layouts. Manufactured in Japan, the bath ships with self-diagnostic safety functions and a built-in drain valve. Yamato facility certifications include ISO 9001:2015 and ISO 14001:2015.
Key Features
- Digital PID Control: microprocessor-driven temperature regulation holds ±1°C accuracy at 60°C.
- Digital Setting and Display: temperature set by ▲/▼ keys with an LED readout for clear at-a-glance monitoring.
- 1 kW SUS316 Heater: stainless pipe heater paired with a Pt100Ω sensor for responsive, precise heating.
- Burn-Protection Cover: aluminum alloy protective reservoir cover shields users from contact with the heated tank.
- Operation Modes: fixed temperature, quick auto stop, auto stop, and auto start cover routine and timed workflows.
- Integrated Drain Valve: built-in drain simplifies water changes and chamber cleanout.
How to Choose the Right Water Bath
Matching a water bath to your protocol comes down to chamber size, temperature performance, and site power. Weigh these axes against your sample volumes and bench space before specifying a unit.
- Capacity: a 7 L chamber suits flask, tube, and small-vessel batches; size the bath to your peak simultaneous sample load.
- Temperature Range: ambient +5 to 95°C covers most warming, incubation, and thawing tasks below boiling.
- Control Type: digital PID control with ±1°C accuracy matters when reproducibility drives your results.
- Voltage: confirm the 115V supply matches your lab circuit before installation.
- Footprint: an 18 × 15 × 14 inch envelope determines whether the unit fits crowded bench space.
- Safety Devices: self-diagnostic overheat prevention and a protective cover reduce operator and equipment risk.

Frequently Asked Questions
What is the temperature range of the Yamato BM401 water bath?
The BM401 operates from ambient +5 to 95°C. Microprocessor PID control holds ±1°C accuracy at 60°C, supporting warming, incubation, and thawing protocols below boiling.
What is the chamber capacity and footprint of the BM401?
The BM401 offers a 7 L working capacity. Its exterior measures 18 × 15 × 14 inches (L×W×H) and the unit weighs 18 lbs, fitting standard bench installations.
What voltage does the BM401 require?
The BM401 runs on 115V. A 1 kW SUS316 pipe heater drives the chamber, so confirm your bench circuit supplies the required 115V before installation.
What materials is the BM401 constructed from?
The exterior is chrome-free electrogalvanized carbon steel with a chemical-proof baked-on coating. An aluminum alloy protective reservoir cover and resin plates complete the build, and a SUS316 heater contacts the water.
How is temperature set and displayed on the BM401?
Temperature is set digitally using ▲/▼ keys and shown on an LED display. A Pt100Ω sensor feeds the PID controller for precise, repeatable regulation.
What safety features does the BM401 include?
The BM401 includes self-diagnostic functions with overheat prevention. An aluminum alloy protective cover shields operators from the heated tank, and a built-in drain valve eases safe water changes.
