Abstract:
The invention discloses disposable polymeric vessels or tip products (26), having a thin area upon at least a portion of the vessel or tip, for use in medical and scientific laboratories. The thin area (38) 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.

Abstract:
A method is provided for the modification of microbial metabolism using a unipolar magnetic field. By applying a unipolar magnetic field to microbes under controlled conditions, changes in the rate and/or efficiency of metabolism are produced. Further, a media which has been subjected to a shielded or focused magnetic field is applied to a subject, as for example, topically. The comprises, in part, interposing between the subjects and the source of a magnetic field, at least one second magnetic field disposed in such a manner that the polarity of the second magnetic field cancels or at least partially neutralizes the magnetic strength of the first magnetic field. The second magnetic fields can also be disposed so as to permit only a portion of the first magnetic field to escape shielding and thereby focused in a predetermined direction.
