A pipetting device includes first and second bodies, through which a plurality of pipettes extend. The surface of one of the bodies is free to move relative to the surface of the other body. Relative motion between the two bodies causes an inter-pipette distance exhibited by the pipetting device to vary.

A composite sealed vessel is provided. The vessel includes a non-metallic, generally cylindrical inner containment piece, a non-metallic, generally cylindrical outer containment piece disposed around the inner containment piece. A pair of non-metallic flanges are disposed at ends of the inner and outer containment pieces to form a closed structure defining a cavity therein. The vessel also includes a metallic external lining disposed over the closed structure to form a leak-tight pressure boundary.

An imaging system including at least one pole piece is described. The at least one pole piece includes at least two grain-oriented sheets that are stacked together, where a direction of easy magnetization of a first of the at least two grain-oriented sheets is different than a direction of easy magnetization of a second of the at least two grain-oriented sheets.

A system for an automated dispensing and retrieval kiosk for recorded media includes a kiosk having a plurality of vertical racks arranged in a circular formation, each vertical rack configured for storing a plurality of recorded media. A customer interface allows a customer to select or return a recorded media. A robotic element delivers the selected recorded media from the vertical racks to a media output, at the customer interface. The element also delivers a returned recorded media from a media input at the customer interface to the vertical racks. A computer controls operation of the kiosk, and an internet interface connects the kiosk to the Internet. The kiosk may communicate with a central server and/or other kiosks of a group, to locate a requested recorded media within a kiosk of the group. Once located within the group, the requested media may be reserved for customer pick-up.
摘要:
A column for use in chromatography, the column having a tube with a bore that can contain a packing medium captured between two porous plugs positioned at opposite ends. End fittings are attached to the tube ends, the end fittings having a duct with a duct opening having a diameter at least as large as the diameter of the tube bore which it faces. The duct opening may be positioned within a recess in spaced apart relation to the porous plugs to prevent the end fitting from contacting the plug and burnishing its surface.

An x-ray detector module including a silicon photomultiplier and a computed tomography imaging system including the same is provided. The x-ray detector module includes optically coupled scintillation materials and silicon photomultiplier pixels. The x-ray detector pixels may have a constant axial profile with a polygonal cross section, which may be rectangular. A plurality of the x-ray detector pixels are generally arranged into 2D arrays. Each x-ray detector pixel may be connected to a dedicated electronic readout channel. In operation, the scintillation materials interact with incident x-ray photons to generate visible-light photons. The silicon photomultiplier pixels generate electrical signals in accordance with the number of visible-light photons generated by an incident x-ray photon. The electronic readout channels process the electrical signals to determine characteristics of the incident x-ray photons. Information of a plurality of x-ray photons are compiled to generate computed tomography images.
