Sealed sample storage element system and method
A system and method operative in accordance with the present disclosure facilitate storage and retrieval of individual or discrete samples of biological, non-biological, and chemical material stored on dry media. Sample material may be disposed upon or within a porous or solid (i.e., non-porous) sample storage medium and subsequently archived in, and retrieved from, storage elements such as multi-well plates, for example, using robotic devices or other automated apparatus. The disclosed system and method enable ejection of sample material from a sealed storage element into a specific well of a multi-well daughter plate, or into a specific cuvette, test tube, or similar container. In some embodiments, a sample carrier comprising a storage medium may be punched or ejected through a first seal of the storage element with an apparatus or implement such as a disposable piercing tip, for instance, inserted through a second seal of the storage element.

Modular test tube rack
A modular test tube rack for assembly with similarly constructed racks comprise a flat rectangular body displaying, in a first position, a series of wells extending from its top wall to its bottom wall and adapt to receive tubes therein. A pair of handles vertically extend at opposite end walls of the body, each handle having a lower portion adapted to tightly engage an extension on each end wall and a hand gripping upper portion. The lower portion has a bottom edge configured to anchor with the top edge of the handle of an underposed similarly constructed rack to thereby enable a stacking of two more of these racks. In one embodiment, the body displays a second series of wells extending from the bottom wall to the top wall whereby the body, when in a second position reversed relative to the first position, may also receive test tubes, the handles being reversably mountable to the end wall extension to still enable a stacking of racks in the second position.

Apparatus for aspirating liquid from a container, e.g., a test tube, having a puncturable stopper includes a pair of stepper motors that share a common linear actuator or drive member. One motor operates to axially advance the linear drive member (preferably a lead screw) to a position in which it serves to position a rigidly connected tube-detector / stripper member in engagement with the top of a stopper on a tube. Thereafter, the second motor operates to move along the surface of the same drive member to advance an aspiration probe through the engaged stopper and into a liquid aspirating position within the tube. Preferably, a linear guide rail, slidably-mounted on a frame that supports the liquid-aspirating apparatus, serves to guide both the movement of the aspiration probe and the linear drive member. As a result of the shared components, the apparatus is highly precise and reliable.
