A new buret stopcock which is said to be nonsticking is offered by the General Laboratory Supply Co. Called the Tapnik, it uses a new diaphragm principle, according to the company, to assure delicate, positive flow control from a drop to a steady stream. Lu brication is not necessary, and the stop cock can be used for both acid and
