Thermometers and Temperature Scales

Any physical property that depends consistently and reproducibly on temperature can be used as the basis of a thermometer. For example, volume increases with temperature for most substances. This property is the basis for the common alcohol thermometer and the original mercury thermometers. Other properties used to measure temperature include electrical resistance, color, and the emission of infrared radiation. As many physical properties depend on temperature, the variety of thermometers is...

Gas Thermometers and the Kelvin Scale

The definition of temperature in terms of molecular motion suggests that there should be a lowest possible temperature, where the average kinetic energy of molecules is zero (or the minimum allowed by quantum mechanics). Experiments confirm the existence of such a temperature, called absolute zero. An absolute temperature scale is one whose zero point is absolute zero. Such scales are convenient in science because several physical quantities, such as the volume of an ideal gas, are directly...

Optimized sampling protocols and the development of new wipe materials can be facilitated by standardized measurements of collection efficiency from wipe-sampling. Our approach for sampling trace explosives uses an automated device to control speed, force, and distance during wipe-sampling followed by extraction of collected explosives.
FAQs
Liquid, electrical, and infrared thermometers translate temperature into signals in different ways. Liquid devices rely on thermal expansion, electrical thermometers detect changes in resistance, and infrared instruments respond to infrared radiation. Because these mechanisms sample temperature differently, the selected device should match the biological material and measurement setting to produce a meaningful reading.
Calibration establishes whether the instrument reports temperature accurately enough for the experiment. Without it, a consistent reading can still be systematically wrong, causing researchers to misinterpret enzyme assays, cell cultures, or microbial growth conditions. Checking calibration before measurements therefore supports comparison among samples and improves confidence that observed biological differences are real.
The probe must be positioned so its reading represents the sample or habitat rather than a nearby surface, container, or surrounding equipment. Allowing the thermometer to equilibrate gives the device time to respond to the measured conditions. Poor placement or premature recording can create values that do not describe the biological system being studied.
Biological measurements may be reported in Celsius, Fahrenheit, or Kelvin, so the unit should accompany every recorded value. A numerical temperature without its scale can be ambiguous and may hinder comparison between experiments or records. Consistent unit reporting helps researchers interpret controlled conditions and relate measurements to biological outcomes accurately.
Begin with a calibrated thermometer, place its sensing component appropriately, and allow the reading to equilibrate before recording it. Keep the measurement process from introducing contamination, particularly when working with biological samples. This workflow links instrument preparation, representative placement, stable readings, and clean handling, making the resulting temperature record more reproducible.
It supports temperature control and monitoring in cell culture, enzyme assays, microbial growth studies, animal physiology, and environmental monitoring. These applications differ in what is being measured, but each depends on temperature values that accurately represent the relevant culture, reaction, organism, or habitat. Reliable measurements help researchers interpret biological behavior under defined or observed conditions.
