The remainder of the sample is kept in a sealed chamber between the piston and the end wall of the tubular body until it is excreted through a second aperture for a secondary test by pushing the piston beyond the trippable stop. That preserves the sample within the spongy swab that has been used to collect it; thus preventing the adsorption of the analytes on the surface of a reservoir, and to provide a convenient and rapid way to extract the remainder of the specimen. | 06-04-2009 |
