Can the laboratory thermometer be filled with mercury

Laboratory thermometers are used to measure temperatures or temperature changes with a high degree of precision. They are made of metal or glass and strengthened through thermal tempering or annealing.

The way a laboratory thermometer works depends upon its type. They are generally a liquid-in-glass device, a bimetallic strip, an electronic thermistor thermometer, or infrared (IR) device.
Liquid-in-glass thermometers are made of sealed glass and contain a fluid, usually mercury or red alcohol, whose volume changes relative to its temperature. The liquid expands as the temperature rises, rising in the tube and indicating the temperature. When choosing a liquid or gas-filled thermometer, there are several things to consider, including: Material in tube - gas or liquid; Material of tube - glass or metal; Level of liquid or gas in the tube.
