Heating constant temperature water bathIt is a commonly used laboratory equipment, mainly used to provide a constant temperature environment for samples, widely used in fields such as chemistry, biology, medicine, materials science, etc.

Working Principle:

Heating system: Heating the water in the water bath through electric heating tubes or heating rods.

Temperature control:

Sensor: Built in temperature sensor (such as PT100 or thermocouple) monitors water temperature in real time.

Controller: Adjust the heating power through PID algorithm or simple proportional control to maintain the set temperature.

Display and settings: The digital display screen or knob sets the target temperature, and some models support programming control.

Circulating system: Some models are equipped with agitators or circulating pumps to ensure even distribution of water temperature and avoid local overheating or overcooling.

　　Heating constant temperature water bathMain types introduction:

普通型：

Basic heating function, with a temperature range typically from room temperature to 100 ℃.

Suitable for simple constant temperature experiments such as dissolution, reaction, etc.

Precision type:

High temperature control accuracy (within ± 0.1 ℃) and good stability.

Suitable for temperature sensitive experiments such as enzyme reactions, cell culture, etc.

Low temperature type:

It can achieve constant temperature control below room temperature (with the assistance of a refrigeration system).

Suitable for experiments that require low-temperature environments, such as PCR, freeze-drying, etc.

Multi functional type:

Integrated heating, cooling, stirring, oscillation and other functions.

Suitable for complex experimental requirements such as multi-step reactions, mixed cultures, etc.
