Abstract
SummaryA sampling procedure, which was developed in order to examine more completely the interior of a drinking glass, proved quite satisfactory and it was used extensively in this investigation.The Steril-Ray Cabinet, employing 4 Sterilamps, was tested while in actual operation at a soda fountain. Dry clean glasses showed but slight bacteriological improvement as the result of being exposed in this cabinet. It should be noted that these were already of low bacterial content without being exposed. Wet clean glasses showed a very marked improvement as the result of being exposed. However complete sterilization did not result in every case.The experimental evidence obtained in this investigation indicates that almost sterile surfaces are produced when clean drinking glasses are irradiated with the ultraviolet light produced by the Sterilamp.
