Abstract

A mixing apparatus comprising: a) a mixing well characterized by an internal volume not exceeding 100 ml; b) a drive mechanism including a stationary circumferential gear on an inner surface of the mixing well; and c) a planetary mixing element driven by a mixing element gear which engages the stationary circumferential gear.

First claim

1 - 35 . (canceled)

36 . An apparatus for transferring a viscous material, the apparatus comprising:
a) a first container capable of containing a viscous material; b) a transfer piston insertable in the first container so that the piston forms a circumferential seal with respect to the container, the transfer piston including a hole; and c) a mechanism for attaching an aperture of a second container to the hole in the transfer piston; wherein insertion of the transfer piston into the first container causes the viscous material to pass through the aperture into the second container.

37 . Apparatus according to claim 36 , adapted to provide sufficient force to cause a viscous material characterized by a viscosity of at least 500 Pascal/second to flow through the aperture of the second container.

38 . Apparatus according to claim 37 , configured so that manual manipulation of the first container and the transfer piston produces the sufficient force.

39 . Apparatus according to claim 36 , wherein the transfer piston is adapted to remove at least a portion of the viscous material from a mixing element as the mixing element is removed from the first container.
