    Abstract: A multi-well assembly including a filter plate and receiver plate. Each plate includes a plurality of wells, which, when the filter plate is placed in nesting relationship with the receiver plate, each filter plate well has a corresponding receiver plate well into which it extends. The receiver plate wells are of a non-uniform cross-section in order to increase the gap between the outer walls of the filter plate wells and the inner walls of a corresponding receiver plate well when the receiver plate and filter plate are in nesting relationship. The increased gap size reduces wicking and cross-contamination. A multi-section well of maximum cross-section in an upper region and a minimized cross-section in a lower region, with a gradual transition between the regions, is thus provided.

    Abstract: A filter vial and piston are provided where the vial has a cylindrical wall with a closed bottom and open top and with the hollow, tubular piston therein. The piston has a distal end covered by a cup having a proximal cup seal extending outward to engage the walls of the vial to form a fluid tight seal with the vial during use. The distal end of the piston has a piston flange extending outwardly and located adjacent a recess in the piston so the cup forms a snap fit over the piston flange and extends into the recess. The piston flange causes the cup to bulge sufficiently outward to form a fluid tight seal with the vial during use. A filter is placed in the bottom of the cup and abuts an inwardly extending lip on the cup. The filter is held against the lip by a piston support at the distal end of the piston. A cup support at a distal end of the cup also helps support the filter.

  • Publication number: 20140050635
    Abstract: Device for the synthesis of peptide-based radioactive drugs, for diagnostic and/or therapeutic use, includes: a frame; a closing case for the frame; a first disposable main module; a second disposable module, slidingly associated with the first module; a third disposable test-tube holder module, reversibly fixable to the frame (100) with fixing elements that allow the translation thereof with respect to the same. The first, second and third modules are arranged for irreversibly coupling so as to form one single disposable collector inside which the whole synthesis process of the concerned radioactive drug is performed, where at the end of the process, the collector may be removed from the device as one single contaminated mono block. The device is controlled by a remote control and drive workstation that includes a computer and devices for storing and managing data concerning the synthesis of the specific radioactive drug obtained for each treated patient.

  • Patent number: 8623641
    Abstract: In a general aspect, an apparatus for washing biological material is provided which includes an outer sleeve, and an inner sleeve disposed within the outer sleeve. The outer sleeve has an open end for receiving the biological material, and an opposed closed end. The inner sleeve is detachably and slidably positioned within the outer sleeve, and includes a first port for receiving and dispensing washing liquid, a second port defining a liquid flow path between an interior of the inner sleeve and an interior of the outer sleeve, and a filter disposed in the second port. The filter allows passage of washing liquid but not passage of the biological material therethrough. A chamber, formed between the filter and the closed end of the outer sleeve, is configured to permit flow of washing liquid via the filter while retaining the biological material therein.
