A Simple Flask Rinser Readers of the Journal of Chemical Education may he faced with the task of rinsing large numbers of flasks time and time again in either a laboratory course situation or in their daily work. Here a t the Indiana State Chemist Laboratory, I ana-, lyze samples for trace elements using large numbers of 100-ml volumetric flasks. I I have solved the rinsing problem by developing a four-position all plastic flask rins- 1 er, which works well on not only volumetric flasks, hut on Erlenmeyer and Florence flasks too. I t may be used, of course, with either tap or distilled water. Bel-Art products of Pequannock, New Jersey (07440) has agreed to manufacture and market the flask rinser. Robert J. Everson
