    Abstract: 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.

    Abstract: A pipettor includes a wash chamber between an upper plate, a lower plate, an upper seal, and a lower seal. The upper and lower seal retain each other and are located between the upper and lower plates. The pipettor includes a gasket located below the lower plate, a pipette tip retained by the gasket, and a piston with a tapered tip that passes through the plates, seals, and gasket into the pipette tip. The upper and lower seal isolate the piston from the wash chamber. The pipettor includes a channel defined by the piston, extending into the pipette tip, and an actuator that advances and retracts the piston. When the actuator retracts the piston such that the piston loses sealing contact with the lower seal and the wash chamber is supplied with wash fluid and pressurized, wash fluid passes through the groove in the upper seal and into the channel

    Abstract: Embodiments of the invention provide a filter kit including filters for processing a biological sample. Some embodiments include a filter cap in a tube kit with a first tube containing a buffer solution and a second tube containing a lyophilized master mix. Some embodiments include a method of processing a sample using the kit including mixing a biological sample in a first tube with the buffer solution, positioning the filter cap in the first tube, positioning a second tube on the filter cap, flipping the first tube, the filter cap, and the second cap to filter the biological sample and buffer solution mixture with the filter cap as it flows from the first tube to the second tube. Some embodiments include structure enabling transfer of materials through inline flow between the tubes. Some further embodiments include integrated structure for sample pulverization with integrated buffer and lyophilized master mix.
