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 is difficult to preserve, and where formerly vaccines were being rendered inactive and administered ineffectively due to their having been denatured by exposure to ambient temperature.Refrigerant: A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle. In most cycles it undergoes phase transitions from a liquid to a gas and back again.Food storage container: Food storage containers are widespread in use throughout the world and have probably been in use since the first human civilisations.Charlotte Canning, Countess Canning: Charlotte Canning, Countess Canning (31 March 1817–18 November 1861), one of the most prolific women artists in India, was the wife of Charles Canning, 1st Earl Canning. Two portfolios in the Victoria and Albert Museum in London contain some three hundred and fifty watercolours by her, the result of four major tours in India.Cold shock response: Cold shock response is the physiological response of organisms to sudden cold, especially cold water.Permissive temperature: The permissive temperature is the temperature at which a temperature sensitive mutant gene product takes on a normal, functional phenotype.http://www.Abe Anellis: Food microbiologist Abe Anellis was born in Mahilyow, Belarus (previously Mogilëv, Russia) on 15 February 1914. He died on 28 August 2001 in Leesburg, Florida.Superabsorbent polymer: Superabsorbent polymers (SAPs) (also called slush powder) are polymers that can absorb and retain extremely large amounts of a liquid relative to their own mass. Horie, K, et.Liquid nitrogen vehicle: A liquid nitrogen vehicle is powered by liquid nitrogen, which is stored in a tank. Traditional nitrogen engine designs work by heating the liquid nitrogen in a heat exchanger, extracting heat from the ambient air and using the resulting pressurized gas to operate a piston or rotary motor.Vacutainer: A Vacutainer blood collection tube is a sterile glass or plastic tube with a closure that is evacuated to create a vacuum inside the tube facilitating the draw of a predetermined volume of liquid. Most commonly used to collect blood samples in venipuncture, they are also used as urine collection tubes and as serum separator tubes.
