Distilled water of the highest purity is necessary for the precise work of a laboratory, for research purposes, pharmaceutical production, etc. Even minor contamination of water can impact the results of experiments in laboratories, which is why water distillation devices are indispensable in these laboratories.\u00a0<\/span><\/p>\n Laboratory water quality is commonly evaluated using internationally recognized standards published by <\/span>ASTM International<\/b>.\u00a0<\/span><\/a><\/p>\n The diagram of a double distillation unit helps users understand the process of functioning of laboratory water distillation systems and why a double distillation system provides better water quality than a single one.<\/span><\/p>\n Bionics Scientific<\/span><\/a> produces high-precision laboratory water distillation systems.<\/span><\/p>\n A double distillation unit is a water purification device used in the laboratory that purifies water by carrying out the distillation process twice in order to purify water from salt, minerals, heavy metals, microorganisms, and other contaminants. In the first step, raw water is converted into steam, and distilled water is obtained. This process is repeated once again in order to increase the quality of water.<\/span><\/p>\n As compared to a single distillation unit, a double distillation unit gives clean and dependable water and can be used in laboratories, pharmaceutical industries, biotechnology, chemical testing, and educational institutes.<\/span><\/p>\n Feed Water -> Primary Distillation -> Condensation -> Secondary Distillation -> Secondary Condensation -> High-Purity Distilled Water<\/span><\/p>\n The above two-stage process makes it possible to remove more impurities from the water and produce lab-quality distilled water.<\/span><\/p>\n The double distillation system is based on the principles of evaporation and condensation.<\/span><\/p>\n The raw water is introduced in the quartz boiler, where it is heated until it is turned into steam form. The non-volatile contaminants are left in the boiler, and only the pure steam passes to the condenser part. Steam is converted to distilled water in the cooling process.<\/span><\/p>\n Instead of gathering this distilled water, the system sends it back to another quartz boiler for another round of the distillation process.\u00a0<\/span><\/p>\n It offers superior heat resistance and does not cause any contamination while heating the water.<\/span><\/p>\n Produces even heat to evaporate water effectively.<\/span><\/p>\n Changes steam into purified distilled water by cooling.<\/span><\/p>\n Keeps condensation in check to improve the efficiency of the water production process.<\/span><\/p>\n Collects laboratory-grade water, which is ready for use immediately.<\/span><\/p>\n A low water cutoff prevents dry burning of the heating coil.<\/span><\/p>\n In case you want to buy a double distillation plant, here are some main factors you should pay attention to:<\/span><\/p>\nContents<\/b><\/h2>\n
