  • Apparatus for the detection of a specifically reacting substance
    Patent number: 5611995
    Abstract: An apparatus detects a specifically reacting substance in a test liquid. The apparatus has a housing and a holding device thereon for holding a test strip. The test strip has a material that transports a test liquid essentially by capillary forces and has an analytical system which indicates the presence or absence of the substance to be detected. The holding device can be attached to the housing with an opening therebetween for allowing evaporation of test liquid. The housing can be elongated for accepting a sample collector therein. A contact mechanism can also be disposed for promoting contact of liquid sample from the sample collector when inserted in the housing, to the test strip held by the holding device.
