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).
Alkali Scientific Bi-directional Liquid Transfer Cap System for 3L High Efficiency Erlenmeyer Flasks, White, with TPE Tube (50cm 1/8" ID 1/4" OD), Vent Filter (0.22 μm Φ24mm), Sterile, 1/pk, 4/cs
Our pre-installed on the High Efficiency Erlenmeyer Flask,which realizes the closed transfer of liquid and reduces the risk of external contami-nation during the process of capping and screwing. Closed system reduces the risks of contamination during liquid transfer. One-piece construction of caps and connectors reduces the risk of leakage and media residue. Caps of various diameters are available and aseptic welding of liquid inlet tubing under normal conditions is supported. High-quality materials and smooth inner wall of the tubing provide an excellent transfer performance. Sterilized by E-beam, SAL=10^-6. Endotoxin-free, and no ingredients of animal origin. Individually packaged in sterile bag.
