  • Publication number: 20050042661
    Abstract: A method for effecting a rapid, comprehensive release of cellular contents, including nucleotides and associated molecules of interest from living cells, using a novel family of quaternary ammonium compounds. Modification of the alkyl chain length of these compounds can enable selective release from different classes of living cells, allowing them to be rapidly distinguished from each other.

  • Publication number: 20030064504
    Abstract: Intermediate guide elements for use in a preparation apparatus for preventing cross-contamination and reducing the formation of residues in the feed lines are provided herein. The intermediate guide element has a main block with a desirable number of through-openings traversing the main block, preferably arranged parallel to one another. Preferably, the guide element has an inlet region and an outlet region, the inlet region being attachable to an end region of a feed line and the outlet region have a guide for each individual through-openings.

  • Publication number: 20020076356
    Abstract: An apparatus is disclosed comprising a supporting plate with bores for receiving sample-receiving vessels and connection means for irreversibly connecting the vessels to the plate. Such an apparatus is useful for connecting individual vessels or sets of vessels used for collecting samples and assembling them permanently into a fixed array for further procedures, e.g., testing of collected samples.

  • Patent number: 5885670
    Abstract: The Conventional Direct Glazing invention concerns a process for securing fixed panes of inorganic or organic glass to vehicles or parts thereof, in which flexible structural components and or sealing strips are prefitted by a weld strip between them and the pane by thermally activating the weld strip and thus producing a seaming effect on the pane, and pane modules thus produced. A pane module thus produced can subsequently be conventionally fitted to the coachwork on the assembly line using fitting strings without any further auxiliaries and working process. Owing to the material used for the flexible structural component and or sealing strip, the sealing quality corresponds to that of direct glazing. If the residual heat from the manufacture of the pane is used as the activation heat for the sealing strip, considerable economies are achieved in the manufacturing process for the pane module.
