Vaccine vial monitor. A vaccine vial monitor ( VVM) is a thermochromic label put on vials containing vaccines which gives a visual indication of whether the vaccine has been kept at a temperature which preserves its potency. The labels were designed in response to the problem of delivering vaccines to developing countries where the cold chain ...
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
Retrieved 4 April 2018. 1.2.3.3 Definition of Room Temperature: According to the United States Pharmacopeia National Forumlary [ sic] (USP-NF), the definition of room temperature is between 15 and 30 °C in the United States. However, in the EU, the room temperature is defined as being 15 to 25 °C, while in Japan, it is defined being 1 to 30 °C.
Extreme heat (and extreme cold) can significantly alter the effectiveness of prescription and over-the-counter drugs. Some medications can tolerate temperatures up to 86 degrees Fahrenheit (30 ...
At room temperature, the pure free base of amphetamine is a mobile, colorless, and volatile liquid with a characteristically strong amine odor, and acrid, burning taste. [22] Frequently prepared solid salts of amphetamine include amphetamine adipate, [217] aspartate, [29] hydrochloride, [218] phosphate, [219] saccharate, [29] sulfate, [29] and ...
Thermal energy storage ( TES) is the storage of thermal energy for later reuse. Employing widely different technologies, it allows surplus thermal energy to be stored for hours, days, or months. Scale both of storage and use vary from small to large – from individual processes to district, town, or region.
Diethanolamine, often abbreviated as DEA or DEOA, is an organic compound with the formula HN (CH 2 CH 2 OH) 2. Pure diethanolamine is a white solid at room temperature, but its tendencies to absorb water and to supercool [ 2] often results in it being found in a colorless, viscous liquid state. Diethanolamine is polyfunctional, being a ...
In the absence of such extreme air-mass changes, diurnal temperature variations typically range from 10 °F (5.6 °C) or smaller in humid, tropical areas, up to 40 to 50 °F (22.2 to 27.8 °C) in higher-elevation, arid to semi-arid areas, such as parts of the U.S. Western states' Intermountain Plateau areas, for example Elko, Nevada, Ashton ...
