Abstract: A universal test-tube rack is configured for mounting on each of a plurality of apparatus for sample preparation. A centrifugal spinning vortex induction apparatus includes a combination centrifuge/vortex including a motor with a rotational drive system on which the portable test-tube rack can be mounted for rotation and oscillation. A feed station, flotation ring and holder can also be provided, each serving as a mount for the test-tube rack, wherein the test-tube rack can be proceed from station to station with the test tubes and samples remaining in the rack and with the relative configuration and orientation of the test tubes remaining substantially the same throughout the process.

Abstract: The invention relates to apparatus for wafer transportation. A handle assembly is engageable with a wafer transfer cassette and has a grip which allows for movement of the wafer transfer cassette. The handle assembly is profiled so as not to interfere with insertion of the cassette into certain apparatuses. The handle assembly is also profiled to allow for easy detachment when the wafer transfer cassette is in such an apparatus, and easy attachment to the wafer transfer cassette.
