Manual Thermometers
Mercury, non-mercury (liquid in glass), or bimetallic thermometers with analog displays, for general and application-specific use, with various temperature-range capacities and accuracies; may be traceable or certified to international standards.
In 1714, the mercury-in-glass thermometer was invented in Europe by physicist Daniel Gabriel Fahrenheit. Typically, the mercury is contained in a reservoir that opens to narrow glass tube. The distance that the mercury flows into the tube is dependent on the temperature to which the thermometer is subjected. The space above the mercury may be filled with air or an inert gas, or it may be a partial vacuum.
Thermometers are calibrated by exposing them to a known temperature and then marking the height of the mercury at that temperature. For example, one might calibrate to the freezing temperature of water (0°C or 32°F) by placing the thermometer in a mixture of ice and water. Then the thermometer could be submerged in boiling water to determine the point where the water changes from a liquid to a vapor (100°C or 212°F).
Mercury thermometers are still considered to be some of the most accurate temperature indicators. They can be used for a wide range of temperatures, from -37°C to 356°C (-35°F to 673°F). Modifications such as adding an inert gas above the mercury or replacing the glass with fused quartz can extend the upper temperature limit to as high as 800°C (1,470°F).
Mercury cannot be used below -38.83°C (-37.89°F), the temperature at which it becomes a solid. Moreover, nitrogen in the thermometer can flow down into the column and become trapped if the mercury solidifies, which makes the thermometer unusable. Use a thermometer that contains a mercury-thallium alloy for measuring lower meteorological temperatures – it will remain liquid to -61.1°C (-78.0°F).
GA International Stain-Proof Xylene-Resistant Labels 0.75" x 0.75" / 19.1mm x 19.1mm Rectangle White From -80°C to +149°C (-112°F to +300°F)
Thermal-transfer printable labels designed for microscope slides. These highly glossy labels repel stains and do not acquire colors from histological stains, such as hematoxylin or eosin. The labels and printed information are xylene-resistant when used in combination with our XAR-class of solvent-resistant ribbons. The print will resist xylene, toluene, alcohol, MEK, and other solvents and chemicals without needing additional protection. Ideal for histology lab applications.
Cole-Parmer Pocket Liquid-In-Glass Thermometer; -5 to 50C, Window Plastic Case, Organic Liquid Fill
These thermometers are ideal for use in laboratory, biology, chemistry, university, photographic, food/beverage, petrochemical, automotive, wastewater and many other general purpose applications. The protective plastic case protects these thermometers from accidental breakage during use and storage. The section of the case that surrounds the bulb has small openings for circulation.

Enviro-Safe non-Mercury thermometers feature an exclusive biodegradable liquid and dye. Easy to read, aesthetically distinctive due to dark green liquid and permanently fused markings. Each thermometer, individually calibrated against NIST traceable equipment, identified by unique serial number for ISO 9000 or other quality systems.
Hach Company Thermometer, Non-Mercury, -30 to 120°F
Compact and durable, non-mercury thermometers enclosed in a protective nylon case. These thermometers are designed for ruggedness and come in many standard ranges. Suitable for all field and portable uses where an unprotected thermometer may break.
Cole-Parmer Digi-Sense Armored Liquid-In-Glass Thermometer; 20 to 500F, 76mm Immersion, Organic Liquid Fill
Ideal for use in application where thermometers needs added protection from minor shocks. Nickel/plated brass armor shell protects these thermometers from accidental breakage during use and storage. The armor case has a screw cap with ring top and viewing window; the lower section that surrounds the bulb has small openings for circulation. Thermometers feature permanently fused markings, blue spirit liquid, white background glass; are also individually serial numbered. Include statement of accuracy and a triangular-style antiroll fitting.
Abcam (R)-(+)-SKF38393 hydrochloride, D1 partial agonist, 5MG

Thermco Products Inc Armored Thermometer Certified at 120°C for Dairies
Autoclave Maximum Registering Thermometers are for validating autoclaves by monitoring the highest temperature attained during a sterilization cycle. These thermometers operate on the same principle as thermometers designed to measure fevers: the highest temperature attained is recorded, and doesn’t recede until the thermometer is shaken down.
