DEVICE FOR DELIVERING MEASURED QUANTITIES OF REAGENT TO AN ASSAY MEDIUM AND METHOD OF ASSAYING A LIQUID AQUEOUS ASSAY MEDIUM

摘要

Device for delivering precise measured quantities of a plurality of reagents with each reagent being incorporated in a device and each being water soluble. The device has a water impervious support secured to one or more faces of which are discrete and separate elements each containing water soluble or dispersible binder and dispersed therein a water soluble or dispersible reagent. The reagent of each element in the device is reactive with at least one constituent in an assay medium or with at least one other reagent on the device.
