Slingshot is a water purification device created by inventor Dean Kamen. [1] Powered by a Stirling engine running on a combustible fuel source, it claims to be able to produce drinking water from almost any source [2] by means of vapor compression distillation, [3] requires no filters, and can operate using cow dung as fuel.
Bottle for distilled water in the Real Farmacia in Madrid. Distilled water is water that has been boiled into vapor and condensed back into liquid in a separate container. Impurities in the original water that do not boil below or near the boiling point of water remain in the original container. Thus, distilled water is a type of purified water.
Laboratory model of a still. 1: The heat source to boil the mixture 2: round-bottom flask containing the mixture to be boiled 3: the head of the still 4: mixture boiling-point thermometer 5: the condenser of the still 6: the cooling-water inlet of the condenser 7: the cooling-water outlet of the condenser 8: the distillate-receiving flask
An azeotropic mixture of toluene and water distills out of the reaction, but only the toluene (density 0.865 g/ml) returns, since it floats on top of the water (density 0.998 g/ml), which collects in the trap. Some high-boiling liquids that have an azeotrope with water can be dried by adding toluene or another azeotrope-breaking solvent to ...
The two hoses connected to the condenser circulate water through the space between the inner and outer walls. In chemistry, a condenser is laboratory apparatus used to condense vapors – that is, turn them into liquids – by cooling them down. [1] Condensers are routinely used in laboratory operations such as distillation, reflux, and ...
Double-distilled water (abbreviated "ddH 2 O", "Bidest. water" or "DDW") is prepared by slow boiling the uncontaminated condensed water vapor from a prior slow boiling. Historically, it was the de facto standard for highly purified laboratory water for biochemistry and used in laboratory trace analysis until combination purification methods of ...
In a chemistry laboratory, a retort is a device used for distillation or dry distillation of substances. It consists of a spherical vessel with a long downward-pointing neck. The liquid to be distilled is placed in the vessel and heated.
used as household water filters and as filters for large particles in the laboratories ••Diatomaceous earth filters like the Berkefeld filter-do- ••Unglazed porcelain filters like the Chamberland filter-do- •Disk filter or Seitz filter: previously used as bacteriological filters; presently obsolete •Sintered glass filter
