Abstract: A disposable biopsy punch, comprising a first shaft and a second shaft pivotally connected at a pivot point. Each shaft terminates in a jaw having a cutting tooth. A first shaft is characterized by having a plurality of shortened guides projecting therefrom, and the second shaft has a plurality of orifices mating with the shortened guides upon closure of the punch, to provide stabilization of the punch. The punch also comprises a sample releasing mechanism.

Abstract: The invention discloses disposable polymeric vessels or tip products, having a thin area upon at least a portion of the vessel or tip, for use in medical and scientific laboratories. The thin area has a thickness of less than 100 microns. Examples of such products are test-tubes, microtubes and multiwell plates. The thin area is transparent, and is advantageous for performance of optical assays, and in performance of attraction and transfer of magnetic particles. Methods for manufacturing the polymeric vessel and tip products are disclosed.
