Abstract
The plunger of the apparatus is prepared by affixing a section of gum tubing 22 mm. in diam., 45 mm. long, and with a 9 mm. bore, to a 9 x 300 mm. glass rod with rubber adhesive; the end of the plunger is tapered or rounded with abrasive paper. The plunger is fitted into a test tube of such diam. as to give a snug fit; the inside of the tube is roughened with abrasive. Small bits of tissue and diluting medium are placed in the tube and homogenized by working the plunger up and down with a rotary motion.
