<p>A modular specimen preparation cartridge with a tubular body with the interior segmented by pressure sensitive membranes that will rupture or open when exposed to a threshold pressure forming a sequence of chambers. Capsules Tilled with reagents or other fluids that will release the contents of the capsules under applied pressuie are contained in the chambers. Filters, temperature control elements, diagnostic test strips, or catalysts may also be in the chambers. The cartridge may be adapted to virtually any sample preparation and/or analysis protocols or to sample type. The cartridge may also be modular and capable of being coupled to other cartridges or storage containers. In one embodiment, the tubular body is compressible and external pressure causes the capsules to rupture releasing the contents into the chamber. In another embodiment, pressure is applied to membranes and reagent capsules through plunger advancement though the center of the body.</p> |
