Jeio Tech Water Baths & Circulators (Shaking / Heating / Refrigerated)
Now you can purchase Jeio Tech's water baths directly from Labware E-shop.
Choose BW Series if you only need standard open-water heating without cooling or external liquid pumping.
Choose BS Series if your samples require constant agitation during temperature incubation.
Choose CW3 Series if your process operates strictly above ambient temperature and requires external liquid circulation.
Choose RW3 Series if your process requires sub-ambient cooling, rapid temperature cycles, or precise low-temperature fluid delivery.
Programmable Models ("P" suffix, e.g., RW3-P, CW3-P) add multi-step temperature ramping and dwell timing functions.
Product Advantages
Safety Features
- Built-in power cutoff circuit with audible and visual alarms:
- Automatic power cutoff to the heater and controller before the unit shuts down in case of overheating.
- Two separate fuses
- Time setting functions for both Automated Run and Off. (except for BW-B and BW-H Models)
- Integrated time setting function for Delayed ON/OFF.
- Operation mode selection function between Automated Run and Manual Run.
- Protection against low fluid level and dry running. (except for BW-B and BW-H Models)
- Intermittent alert sounds along with a visual alarm on the control panel.
- Automatic shut down of the heater following the alarms to protect users and samples.
User-friendly Control Features
