Abstract:
A magnetic spring actuator comprising a ring (90), a piston (92) movably disposed inside of the ring, and a non-magnetic holding cylinder (94). At least one of the ring and the piston is magnetic. Due to a magnetic force caused by at least one of the ring and the piston, the piston is initially located in a first position with respect to the ring. Application of an outside force results in movement of the piston to a second position with respect to the ring. The magnetic force produces a return force for causing the piston to return to the tirst position with respect to the ring. Alternatively, the piston can be fixed and the ring can be adapted for moving with respect to the piston in a similar manner. A bi-metal coil spring (148) may be wound around the piston.
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:
Macromolecules from a sample are electrophoresed and the obtained electrophoretogram is contacted with a planar matrix of magnetic particles. The magnetic particles having binding specificity to one or more specific species of biological macromolecules, whereby the one or more specific macromolecules bind to the particles in the matrix. The particles can then be collected on the basis of their magnetic properties and the bound macromolecules can then be separated from the particles.
