General Purpose Glass Thermometers are liquid-in-glass thermometers used for routine temperature measurement in school laboratories, science classrooms, preparation rooms, and general laboratory work. This category includes green filled glass thermometers, red spirit glass thermometers, kerosene glass thermometers, and low range glass thermometers in 305 mm formats, giving users practical options for different teaching and measurement needs.
Green filled and red spirit glass thermometers are suitable for everyday temperature checks where a clear, easy-to-read laboratory thermometer is required. Their simple glass construction makes them useful for education, bench work, demonstrations, and routine sample or water bath temperature checks where the selected thermometer range matches the task.
Kerosene glass thermometers are included for certified temperature measurement applications where the supplied model includes certification. Certified thermometers are useful when users need documented temperature reference support for classroom preparation, laboratory checks, or controlled practical work. Low range glass thermometers with 305 mm total immersion design are suitable for applications where the thermometer is used according to its stated immersion type.
Users should select the thermometer based on temperature range, fill type, readability, certification requirement, and immersion method. Total immersion thermometers must be used in the correct way for the most reliable reading, with the bulb and liquid column exposed to the measured temperature according to the thermometer design. Glass thermometers should be handled carefully, cleaned after use, and stored safely to reduce the risk of breakage.
For technical reference, ASTM E1 covers construction requirements for ASTM liquid-in-glass thermometers graduated in Celsius or Fahrenheit, while ASTM E2251 covers ASTM liquid-in-glass thermometers using low-hazard precision liquids. ISO 386 provides principles for the design, construction, and use of liquid-in-glass laboratory thermometers, although it is a withdrawn standard and should be treated as a historical technical reference. NIST liquid-in-glass thermometry resources also provide useful background for calibration and recalibration practice. These references should not be used as product-specific compliance or calibration claims unless supported by manufacturer documentation.
For LabChoice Australia customers, General Purpose Glass Thermometers provide a practical range for schools, universities, teaching laboratories, and general science work where simple, readable, and application-matched glass thermometers are required.
