ABSTRACT:
The invention concerns a procedure for keeping and taking into use an analytic reagent or another substance used in analyses, and a reagent package to be used in the procedure. The package consists of a gas-tight sachet or of a combination consisting of several sachets, where the sachets comprises at least one flexible wall and a blank for forming a discharge aperture. The blank may consist of a hermetically sealed flexible tube extending into the interior of the sachet or a bar-like member with openings defined therein that extend into the sachets. The taking into use of the substance packed in the sachet is then accomplished by opening the flexible tube or the openings in the bar-like member and connecting the tube or the openings to the analyzer with an outward gas-tight connection. The substance is thereafter drawn from the sachet into said apparatus in one or several steps so that the sachet will collapse in connection with the discharge. Thanks to the gas-tight sealing of the sachet and of the connection between it and the analyzer, the substance packed in the sachet remains sterile and unchanged of its concentration not only before the substance is taken into use but also up to such time when the substance has been used up.
