TLDR
In this article, an analyzing cartridge has a plurality of reservoirs and capillaries connected for communication between these reservoirs, and provided therein with a reagent required for analyzing, wherein the reservoirs are provided with openings leading to the outside of the cartridge, and the openings are covered with vents each consisting of a gas-permeable/non-liquid permeable, hydrophobic, porous film.Abstract:
An analyzing cartridge having a plurality of reservoirs and capillaries connected for communication between these reservoirs, and provided therein with a reagent required for analyzing, wherein the reservoirs are provided with openings leading to the outside of the cartridge, and the openings are covered with vents each consisting of a gas-permeable/non-liquid-permeable, hydrophobic, porous film. The analyzing cartridge requires only trace amounts of a sample and a reagent and no maintenance, is suitable for POC analysis or the like, and is provided with a non-fluid reagent in vent-carrying reservoirs, thereby making it possible to formulate a very trace amount of reagent solution in the cartridge by injecting a reagent dissolving liquid into the reservoirs immediately before analyzing. A liquid feed control device which controls the feeding of the liquid between the reservoirs via the capillaries when it is attached to the analyzing cartridge to allow or control an air entry/exit via the vents.read more
