Water Still, also known as a distillation apparatus, is a laboratory equipment used to purify water by separating impurities from it. It works by heating water to its boiling point, which produces steam. The steam is then collected in a condenser, where it is cooled and turned back into the water. This process removes impurities, such as minerals and bacteria, from the water.
Water stills are widely used in laboratories for various applications, including research and analysis, medical and pharmaceutical purposes, and testing and quality control. They are designed to produce high-quality, pure water with minimal impurities.
There are various types of water stills available in the market, including electrically heated, steam-heated, and solar stills. Electrically heated water stills are the most commonly used type, as they are easy to operate and provide consistent results. They are equipped with heating elements that are connected to a power source, which heats the water in the still.
Steam-heated water stills, on the other hand, use steam generated by an external boiler to heat the water. They are ideal for large-scale operations and can produce a large amount of pure water quickly.
Solar stills use the heat from the sun to evaporate water and produce steam, which is then collected and condensed into pure water. They are eco-friendly and cost-effective but may not be suitable for all applications due to their limited capacity and dependence on sunlight.
Overall, water stills are an essential piece of equipment in any laboratory that requires pure water for experiments or processes.
