Cenlee Thermostatic Water Bath Dual View LED Stainless Steel Circulating Bath for Distillation Drying Sample Incubation Lab
1. Dual-Window Observation Design HH-40 features front and rear tempered-glass observation windows, allowing users to clearly monitor samples and experimental conditions during operation. The transparent design reduces the need to frequently open the lid, helping maintain a more stable temperature environment while improving convenience for laboratory research and testing.
2. Precise Digital Temperature Control Designed for reliable constant-temperature applications, HH-40 provides a working range from room temperature +5°C to 100°C. Temperature fluctuation reaches ±0.1°C and uniformity is ±0.2°C. The dual-row LED display clearly shows actual and preset temperatures for easy monitoring and repeatable experimental results.
3. Efficient Water Circulation System The built-in circulation pump continuously moves water inside the chamber to improve temperature distribution and reduce hot or cold spots. Stable circulation helps create a uniform temperature field, making the unit suitable for sample conditioning, chemical experiments, research testing and other temperature-controlled laboratory processes.
4. Durable Stainless-Steel Chamber The inner tank and top cover are made of corrosion-resistant stainless steel for durability, easy cleaning and long-term laboratory use. The 400 x 350 x 300 mm chamber provides sufficient working space for beakers, flasks, test tubes and other laboratory vessels, supporting efficient batch processing.
5. Versatile Laboratory Applications HH-40 combines simple operation, clear observation, stable heating and convenient circulation in one compact system. It is suitable for universities, research laboratories, chemical analysis, quality control, metrology, pharmaceutical research, material testing and other applications requiring controlled and consistent temperature conditions.
