Water Bath Analog 4L Overview
The Water Bath Analog 4L (model BM100) is a compact benchtop water bath from Yamato Scientific, sold by LabSupplies.com as an authorized dealer. Engineered with a 4 L tank and an operating range of ambient +5 to 95°C, this unit handles routine sample warming and incubation. Analog control keeps daily operation straightforward for technicians.
Construction pairs a chrome-free electrogalvanized carbon steel exterior, finished in a chemical-proof baked-on coating, with an aluminum alloy protective reservoir cover and resin plates. A 500W SUS316 pipe heater drives temperature, while a liquid-expansion sensor and ON/OFF control regulate it to ±2°C at 60°C. Internal tank dimensions measure I.D. 200 × D120 mm.
Model BM100 runs on 115V; BM110 covers 220V installations. Each ships at roughly 10 lbs with a 15 × 11 × 8 in footprint that fits crowded benches. Manufactured in Japan, the bath comes from Yamato's ISO 9001:2015 and ISO 14001:2015 certified production. Safety devices include a bath protection cover, 7A overcurrent fuse, and thermal fuse.
Key Features
- Analog control: simple ON/OFF temperature regulation with glass thermometer indication for direct readout.
- 4 L protected tank: I.D. 200 × D120 mm reservoir with a protection cover that guards against contact burns.
- 500W SUS316 heater: stainless pipe heater paired with a liquid-expansion sensor holds ±2°C at 60°C.
- Included bar thermometer: 10–110°C thermometer with immersion line verifies actual bath temperature.
- Layered safety: bath protection cover, 7A overcurrent fuse, and thermal fuse protect operator and unit.
- Voltage options: BM100 for 115V circuits, BM110 for 220V installations.
How to Choose the Right Water Bath
A water bath should match the volume, temperature window, and bench power of your workflow. Use these axes to confirm the right configuration before ordering.
- Capacity: the 4 L tank suits small batches of tubes and flasks; size the reservoir to your typical sample load and vessel count.
- Temperature range: ambient +5 to 95°C covers thawing, incubation, and warming protocols below boiling.
- Control type: analog ON/OFF control favors routine, set-and-hold tasks over programmable ramping.
- Voltage: select BM100 for 115V or BM110 for 220V to match your facility's circuit.
- Footprint: a 15 × 11 × 8 in profile fits tight benches; verify clearance and drainage access.
- Safety: the protection cover and dual fuses matter for unattended or shared-bench use.
