LEON S. MEDALIA 



Fig. 4. Automatic 10 cc. Filler 



The flask of culture media is inverted and attached by a rubber tube to the 

 10 cc. automatic pipette (pipette Vanier) consisting of a three-way stopcock which 

 allows the fluid to run into the inside tube which, when filled, measures exactly 

 10 cc. Any excess fluid flows over into a surrounding tube, which may be emptied 

 by the side stopcock.
