A bottle shaped flask is a common household material with multifarious benefits. The primary usage of a flask is for storage of liquids, both in hot or cold form. For storing cold liquids or those in room temperature, a normal storage container is adequate. These are commonly known as water bottles. These bottles or flasks are available in various shapes or storage capacity and different materials are used in their construction, like plastic or stainless steel. For storing hot liquids or maintaining liquids at constant temperatures, a special type of container is used. These are known as vacuum flask flasks.
Vacuum Flask – Construction and Uses:The vacuum flask was invented by Sir James Devar in 1892. This bottle shaped flask is generally made from metal like steel, though glass and aluminum are also used nowadays. The basic principle behind its maintenance of constant temperature is the placement of two containers, one inside the other. The inner container is smaller than the outer one, creating a space between them. The containers are fused at the neck and the enclosed space is emptied of air. This creates a near vacuum, which significantly reduces the transfer of heat outside.
Initially, brass or other heavy metals were used in its construction. For example,
vacuum flask manufacturer in Delhi makes laboratory equipment using this double-walled vacuum concept for keeping liquids at constant temperatures. This technology also prevents volatile liquids or gasses kept in liquid form from reacting at room temperatures. The most popular usage of this concept is seen in the vacuum flasks used by most households for keeping liquids at constant temperatures for long periods of time.
Types of Vacuum Flask:The most common types in this category are the vacuum flask and coffee pots.
Vacuum Flask:These are generally handy apparatus used for storing liquids. The inner container is generally made of mirrored glass to prevent evaporation of heat or cold. Modern innovations include implementing new technologies like vapor cooling and radiation shielding on the neck joints for more efficient temperature control. A vacuum flask manufacturer in Delhi may manufacture these types of flasks for the city’s residents for storage of hot water during the chilly winters.
Coffee Pots:These are also common household utensils made by many coffee pot manufacturer in India. These pots also use the same principle to keep beverages warm for long periods, often up to six hours. The coffee pot manufacturer in India generally uses 304-grade stainless steel in the construction, which is consequently quite safe for regular use.
