Abstract: Described is a pipette tip rack (100) and methods of making the same. The pipette tip rack is constructed of biodegradable material so that it can be disposed of in a landfill without significant environmental impact. The rack may be structured from folded sheet material, generally in the manner of a cardboard box, such that it is sufficiently rigid for practical use in pipetting procedures. The rack may be fashioned in various other configurations, such as any of the known arrangements used to hold test tubes or pipettes (300) in a specified orientation. The tip racks are sufficiently robust to withstand the loads inherently encountered as a pipette probe engages tips stored in them and are biodegradable within a practical time frame.

Abstract: A novel system, apparatus, composition and method provide facile collection of a physical sample, including in particular noninvasive extraction of buccal cells, specifically directed to capture of PCR-ready DNA from such cheek cells. It is particularly useful in achieving simplified collection, transit, processing and storage of biological samples with minimal chain of custody.

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: Described are pipette tips and methods of making the same. The pipette tips may include at least two components, an annular component and a tubular body component. The annular component may comprise a different and relatively more compliant material. The annular component may be partially or entirely telescopically received within the tubular body component. Alternatively, the annular component may comprise a proximal end of the pipette tip and the tubular body component may comprise a distal end of the pipette tip. A portion of the tubular body component may be telescopically received by the annular component or otherwise attached thereto. The pipette tip may be formed by first molding the annular component and next molding the tubular body component. Alternatively, the tubular body component may be molded first and the annular component may be molded within, adjacent, or about the tubular body component.

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.
