A constant temperature water bath is a commonly used equipment in laboratories, mainly used for distillation, drying, and concentration of chemical or biological products. It can also be used for constant temperature heating and other temperature tests. It is an important tool in the fields of biology, genetics, viruses, aquaculture, medicine, health, laboratories, analysis rooms, education and research.

The purpose and precautions of a constant temperature water bath:

Standardized grounding: Before use, check whether the equipment is reliably grounded.

Avoid dry burning: After adding water, turn on the electricity to avoid water or dry burning, so as not to damage the heating tube.

Water level control: The water level should be higher than the heating tube, but not too high, to prevent overflow or water from flowing into the control box.

Cleaning and maintenance: After use, it should be cleaned in a timely manner to keep the inside and outside clean and avoid the formation of scale. It is recommended to use purified water.

Regular inspection: Regularly inspect the equipment, including the contact status of each component and contact point, to ensure good operation.

Instrument maintenance: When performing instrument maintenance, maintenance records should be filled out.

Power requirements: A standardized power supply should be used to ensure that the power outlet matches the device.

Installation environment: The equipment should be placed on a flat and dry workbench.

Temperature control operation: When setting the desired temperature, it should be noted that the scale of the temperature controller is for reference only and not the actual temperature.

Exception handling: In case of temperature control failure, try cleaning the silver contacts on the controller with a fine sandpaper.

Long term non use: When not used for a long time, the water should be removed and kept dry.

Following these precautions can ensure the accurate operation and prolonged use of the thermostatic water bath.
