A quantitative measuring instrument includes a casing with a cavity for a reagent strip handling mechanism. The mechanism includes a slide with a resiliently biased toggle member for providing snap action of the slide between an open, reagent strip loading position and a closed, quantitative measuring position. A light seal is mounted on the toggle member that engages each reagent strip in the closed position of the slide. In a first, alternative embodiment of the instrument, the slide mechanism includes a cam arm that engages cam surfaces on the instrument raising the cam arm to an open, reagent strip loading position from a closed, reagent strip holding position. In this embodiment the slide can be removed from the instrument and cleaned. In a second alternative embodiment the slide includes a first detent corresponding to a closed position of the slide and a second detent corresponding to an open position. A pair of spring fingers are mounted in the cavity of the instrument casing. One of the spring fingers engages the first detent in the closed position and the second spring finger engages the second detent in the open position providing resistance that defines the two positions. The slide in this embodiment can also be removed and cleaned.

A two-piece slide dispenser includes a housing defining an internal compartment for the storage of a plurality of reagent slides or similar items. The housing includes a dispensing opening and a loading opening. A finger or similar structure at least partially obstructs the dispensing opening to prevent inadvertant falling out of the reagent slides. A one-piece, multiple function, resilient spring boot including a biasing portion and a light and humidity sealing portion is also provided. Once reagent slides are loaded through the loading opening into the internal compartment, the spring boot is mounted in the compartment to engage the slides biasing them toward the dispensing opening. The biasing portion of the spring boot can be hemispherical or of a similar configuration allowing this portion to fold into itself. The biasing portion also includes an extension extending from the hemisphere to engage the slides. The sealing portion of the spring boot includes a lip or edge that can be secured on the housing around the loading opening. In an alternative embodiment, the lip or edge of the spring boot engages the inner peripherial surface of the housing adjacent the loading opening and the loading opening is closed by a cap.

A method for controlling a liquid volume flowing onto a reactive surface which includes a sample application port, two systems of capillary channels, a reaction chamber, and an overflow chamber. The liquid sample to be analyzed is applied to the sample application port which gives the liquid entry to a capillary channel leading to the reaction chamber which contains a material capable of detecting the component of interest in the liquid. When the reaction chamber is filled, the remaining liquid will flow through another capillary channel to an overflow chamber. The capillary channel leading to the overflow chamber is controlled so that liquid cannot flow back into the reaction chamber.
