A Traveling Field Laboratory

A Traveling Field Laboratory

An apparatus for water purifying purposes recently introduced by the New Jersey State Department of Health, is described in a report as “a traveling field laboratory mounted on a motor chassis. In outward appearance the vehicle resembles a delivery wagon. The closed and covered body has doors in front and in the rear and forms a small room used primarily for bacteriological work. On one side of the inside wall is a bench or shelf upon which rests two incubators which are heated by electricity from a storage battery, which also operates the starting and lighting system of the automobile. The shelf also provides enough room for the making of culture plates and for their examination for the purpose of counting the germs. The incubators may also be removed, and, by changing the voltage of the heating lamps, may be used on any 110-volt circuit at any water pumping or filtration plant. Another portion of the equipment carried by the automobile is a portable chlorine gas disinfecting apparatus bv means of which any water supply found to be unsafe may be purified by the addition of chlorine gas. By means of this traveling laboratory the necessary inspection of water supplies in various remote parts of the state has been greatly expedited.”
