  • Device and process for testing a sample liquid
    Patent number: 7731907
    Abstract: A device and a process for testing a sample liquid in which especially the ELISA process can be carried out very easily, rapidly and with high precision. To do this, a sample liquid and a dilution liquid are each supplied to several metering chambers of different volumes, so that the sample liquid can be diluted into assigned reaction chambers in one dilution step in different dilution ratios. Different liquids can be supplied in succession to the reaction chambers by means of a common receiving chamber. The liquids are transferred from the reaction chambers into the assigned test chambers to stop the detection reaction.
