Abstract: A pipette tip plate includes individual tips organized in ranks and files to match in pattern the array of wells in a standard well plate and held together by a web structure which permits individual tips to move into registration with individual pins of a robotic head.

Abstract: A DNA sequencing tray (92) holds an array of sample wells (82) in a rank and file pattern by means of rigid file members (85) connected by flexible mechanisms (87) permitting the pattern to be expanded to change the center-to-center spacing between adjacent wells (82) form 9 mm to 10.8 mm.

Abstract: A pipette tip device. The device includes a plurality of interconnected pipette tips disposed in substantially parallel orientation and in side-by-side alignment. The tips are hollow and each tip includes a tip body and a flattened distal extremity. The flattened distal extremities are all disposed in substantial co-planar alignment common to a single plane to thereby enable simultaneous insertion of the flattened distal extremities between closely spaced-apart plate surfaces.

Abstract: A cryogenic freezing vial. The vial includes a hollow sample container having exterior threads seated inside a hollow outer container having interior threads. The two containers define a surrounding volume there between which operates as a thermal barrier to resist temperature change within the sample container. A cap having a tubular wall extending outwardly from a continuous capping surface includes threads formed on both of the opposing sides of the tubular wall. The inner threaded side of the tubular wall can be screwed onto the hollow sample container, and then the outer threaded side of the tubular wall can be screwed into the hollow outer container. In such manner the cap is disposed in simultaneous threaded engagement between the two containers to intercouple and seal the containers from their surrounding environment.
