A splicing assembly for rolled sheet material, including first and second shafts for support of sheet material and a drive assembly for selectively dispensing sheet material. The assembly further includes a splicing apparatus for uniting a replacement with a winding down roll, and an egress guide assembly for receipt of dispensed sheet material exiting the splicing apparatus and passage of same intermediate the shafts. The splicing apparatus includes first and second sealing elements, and first and second carriages adapted and disposed for translation towards their respective sealing elements, a free end portion of sheet material of the replacement roll supported upon the first/second shaft for selective retention by the second/first sheet material carriage, and for translation to, and thereafter with, a portion of sheet material of the winding down roll supported upon the second/first shaft for urged combined engagement with a corresponding sealing element.

Some embodiments include a scanning module with an optical reader coupled to a moveable carriage configured to move the optical reader in a first direction. In some embodiments, the optical reader includes excitation sources, emission detectors, emission energy conditioning elements, and a tape drive configured and arranged to selectively advance a tape in a second direction which is substantially perpendicular to the first direction. Further, some embodiments include a bar code reading station positioned adjacent to the moveable carriage. Other embodiments include an objective lens.

Scanner photometer and methods

A scanning photometer and attendant methods are provided. The scanning photometer is generally characterized by first and second fluorophore excitation sources, an objective lens, and a common emission detector for the detection of first and second fluorophore emission originating from the excitation of the fluorophores via passage of excitation energy, via an optical path of the objective lens, from the excitation sources. Excitation energy and emission energy conditioning elements are likewise provided, operatively interposed before or after the objective lens as the case may be.

An apparatus () for singulating micro-well tape includes a tape drive () and a cutting assembly (). The micro-well tape is advanced into and passes between upper and lower tape retainers (), with the upper tape retainer () including a groove () into which a raised ridge () of a multiplicity of ridges () of the bottom tape retainer () extends, with the rows of wells moving between adjacent ridges () in a movement direction. When a bar code on the micro-well tape is detected by a sensora knife blade () mounted on a slide block () is moved vertically to cut the micro-well tape. The new leading edge of the micro-well tape pushes the cut micro-well tape which is deflected by the raised ridge ().
