DESCRIPTION

Exhibit 336 is a centrifuge machine consisting of a heavy cast iron base supporting an iron column which can be rotated by a round belt running in a brass pulley located about 2/3 of the way to the top which ends in a horizontal disk with 4 tube holders. In these tube holders which are free to rotate about horizontal axes there are still glass test tubes. The upper part of the instrument consists of a cylindrical iron shield having a diameter greater than the extension of the tube holders in the horizontal position they assume when the column is spinning very fast.
