  • Publication number: 20150004056
    Abstract: A method for sanitizing/sterilizing a container/enclosure for use in the food industry or the beverage industry comprising the steps of: providing a container and/or enclosure; providing a hollow or non-hollow electromagnetic radiation source; controllably exposing the container and/or enclosure to electromagnetic radiation from the electromagnetic radiation source for a period of time; and at least one of sanitizing and sterilizing at least a portion of the container and/or enclosure with the electromagnetic radiation.
    Type: Application

  • Patent number: 5753186
    Abstract: A disposable reaction vessel for performing nucleic acid amplification assay. The disposable reaction vessel has a penetrable cap that can be penetrated by an automated pipettor to aspirate a portion of an amplified reaction product. The disposable reaction vessel contains the reagents necessary to perform a nucleic acid amplification assay. A patient specimen is added to the unit dose reagents in the disposable reaction vessel and the penetrable cap is closed. The disposable reaction vessel containing the reaction mixture and the specimen undergoes amplification, typically by placing it in a thermal cycler. After amplification the intact disposable reaction vessel is transferred to an automated analyzer where an automated pipettor penetrates the closure membrane and aspirates a portion of the amplified sample for further processing, without removal of the reaction vessel cap. This avoids the generation of potentially contaminating aerosols or droplets.

  • Patent number: 4934545
    Abstract: A closure containing an internalized microbial filter for use in enteral delivery set assemblies. The closure comprises a generally cylindrical side wall, a planar top surface having first and second projections, the first projection being associated with the spikable membrane while the second projection is associated with a filter and with means to limit air access to the filter. The closure also includes a bottom surface having an aperture which extends through the closure to the top surface thereof with the filter being secured to the bottom surface and extending across the opening of the aperture.
