We, at East Oxford Solutions have developed a novel Phase Change Technology through which we are able to maintain the temperature inside the given chamber between a given temperature band width for a period of 120 - 144 hours. The possibilities of this technologies are diverse, but we are inclined towards storage of vaccines, they can be stored at a temperature of 2 degrees to 8 degrees for a period of 6 to 8 days. This temperature range is specifically selected so that all types of vaccines can stored without any change in their properties.
