International Classification:

B01L 302
G01N 116

US Classification:

422100

Abstract:

A syringe array (10) for holding a plurality of syringes (12), each syringe having a barrel (14), a plunger (18) and a needle (16), the syringe array (10) including a distal assembly (50) which holds the plungers (18) of the plurality of syringes (12) and by which all of the plurality of plungers (18) are urged to move in unison, a pivot assembly (52) wherein a portion of each the barrels (14) of the plurality of syringes (12) is pivotally attached to a pivot (92, 94) and a proximal assembly (48) wherein each needle (16) of the plurality of syringes (12) is positioned with a controlled center-to-center spacing (100, 102) from each other. An adjusting portion (62, 64, 70) of the syringe array (10) is adjustable to controllably change the needle center-to-center spacing from a first spacing (100) to at least a second spacing (102) as the barrel portions (14) are allowed to rotate about the pivots (92, 94).

International Classification:

G01N 2103
B65D 5516

US Classification:

422102

Abstract:

A locking microcentrifuge tube (10) is provided which is capable of being sealed in either of two manners, one being a friction-fit seal which is easily opened and the other being a "locked" seal for higher stress applications. The tube body (12) is adapted to mate with the cap (14) at an aperture (24) such that the plug portion (36) of the cap (14) and the aperture (24) form the friction-fit seal at the early stages of insertion. A collar (26) is provided about the aperture (24) on the tube body (12). The collar (26) is formed to include one or more circumferential projections (28, 30). The cap (14) is formed to include depressions (32, 34) adapted to mate with the projections (28, 30) upon full insertion of the plug portion (36) to create the "locked" seal. The cap (14) is secured to the tube body (12) by a hinge (38) and a tab (40). The primary usage of the locking microcentrifuge tube (10) is in biomedical laboratory analysis.

US Classification:

Abstract:

A multi-well container (10) is provided in which a greater number of wells may exist than heretofore possible while still maintaining a standard multi-well plate tube array format and footprint. The multi-well container (10) is comprised of a rectangular array of tubes (12) in standard tube format held together by an integrally fashioned plate portion (16). The tubes (12) are subdivided by partitions or septa (14) which extend the height of the tubes (12). Each septum (14) may constitute a single wall or may be comprised of any number of fins (32) which are integral with internal tube surfaces (28). In a symmetrical design with four such fins (32), the fins (32) radiate at angular intervals of 90 degrees from a common central axis (34) with which all four fins (32) are integral. Thus, the septa (14) serve to compartmentalize each tube (12) into symmetrical quadrants of four smaller wells or sub-tubes (30). The preferred embodiment is directed toward usage in conjunction with PCR thermal cyclers, but the multi-well container (10) and the elements as are embodied therein are generally applicable to any laboratory procedure where multiple samples must be treated, evaluated, or stored.
