In a lab (or a kitchen) it is often esssential to keep a liquid mixture at an exact temperature without a gradient of heat (the bottom being hotter than the top) to make it “cook” properly. To do this scientists (and cooks) often submerge the vessel needing this controlled environment into a bath of water at a controlled temperature. The advantage is that the water in the wath presents the heated material with a constant temperature that will not exceed 100oC (the boilling point of water) so that over heating or scorching is avoided. The laboratory water bath is slightly more complex than the kitchen version (the double boiler) as the temperature can be controlled through sensors to wthin a degree of the desired temperature.

Water bath is a device used for regulating the temperature of substances subjected to heat. The vessel is surrounded by another vessel containing water which can be kept at a desired temperature. Water bath is frequently used in chemistry labs for a number of temperature related applications. Water baths are used to heat those substances, which can’t be heated directly on Bunsen burner or hot plate or any other media. However only those materials can be heated with water bath whose boiling point is less than that of water.

The water bath is used in the lab to allow a chemical reaction to occur at a specific temperature. The bath is heated to a precise temperature and the beaker or other container is placed in the bath.

Now we would like you tell you the working principle of water bath and several FAQs.

What’s the working principle of water bath?

Working principle of water bath: The Cu50 sensor transfer water temperature to resistance value, amplified and compared by integrated amplifier, then output the control signal, efficiently control the average heating power of electric heating tube and maintain water in constant temperature. When you require balanced high temperature heating that no more than 100℃, water bath is a good choice.

Frequently asked question of circulating water bath?

1.What’s the highest temperature of GY series circulating water bath?

The temperature range of circulating water bath is room temperature to 99℃, and if the medium is oil, the temperature range of oil bath is room temperature to 300℃.

2. Is GY series high temperature circulating water bath only used for water bath?

The GY series circulating water bath can be used for water bath as well as oil bath.

3. Which oil can be used in constant temperature bath kettle?

Answer: High temperature conduction oil is acceptable, or methyl silicone oil, but please note oil viscosity when buying oil, the higher of the viscosity, the worse of the constant temperature accuracy; whereas, the lower of the viscosity, the better of constant temperature accuracy.
