NOTE ON STqRTING CARBOY SIPHONS C. E. WHITE,UNlVBRSITY
OF
MARYLAND, COLLEGEPARK, MARYLAND
When one desires to get one or two bottles of acid from a carboy it is often too much trouble to use th? rocker, and a pump is not always on band to start the siphon., For this purpose we are using a method illustrated in the figure and find it very convenient. To start the siphon, pincbcocks B and C are opened and the same liquid poured into E as is in the carboy, nntii the tube is full. The tubes are then closed a t B and C and the rubber tubing a t C is slipped off of the glass connection. The liquid may then be run out as desired. If glass-blowing facilities are avail8 Carboy able a two-way stopcock and an B Pinch Cock outlet tube a t F would be better C Pinch Cock than the rubber connections. For D Glass Connection light liquids such as ammonium hydroxide, hydrochloric acid, and nitric acid, 10 mm. glass tubing may be used. For sulfuric acid it is necessary to use a smaller tube.
