Cenlee Bench Top 4-Hole Laboratory Water Bath 220V PID Temperature Control for Education Research and Sample Processing

1. Adjustable Openings for Different Lab Vessels Each working position is equipped with a removable concentric ring lid. Users can adjust the opening diameter according to the size of the vessel, making the HH-4 compatible with beakers, flasks, test tubes and sample bottles. The lids also help reduce heat loss and improve heating stability during routine experiments.

2. Compact Design with Practical Working Capacity With overall dimensions of 345 x 345 x 195 mm, the HH-4 provides four heating positions without occupying excessive bench space. Its double-row structure makes efficient use of the laboratory worktop and is suitable for laboratories, testing rooms, teaching facilities and research workstations with limited installation space.

3. Convenient Water Replacement and Maintenance The built-in drain outlet allows users to discharge water directly from the inner chamber, reducing the need to lift or tilt the equipment. Combined with the smooth stainless steel tank surface, this design makes routine water replacement, cleaning and maintenance faster and more convenient.

4. Clear Digital Monitoring for Daily Operation The front-mounted digital controller provides a clear view of the operating temperature and settings. Users can conveniently set and monitor the required temperature during experiments. The independent side power switch further simplifies operation and helps create a more organized laboratory workflow.

5. Suitable for Multiple Temperature-Controlled Procedures The HH-4 supports biological research, pharmaceutical preparation, chemical testing, aquaculture analysis, hygiene inspection and educational experiments. It can be used for sample preheating, reagent tempering, incubation, dissolution, concentration and other laboratory procedures requiring a stable water-bath environment.
