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.
Claims17
Device for testing a sample liquid, comprising:
- a first common receiving chamber means for receiving the sample liquid,
- a plurality of first metering chamber means for holding the sample liquid which are connected to the first receiving chamber means,
- at least one second common receiving chamber means for holding a dilution liquid arranged parallel to said first common receiving chamber means,
- a plurality of second metering chambers means for exclusive metering of dilution liquid received from the second receiving chamber means,
- a plurality of reaction chambers, each of which is connected separately to said first and second metering chambers means
- wherein at least one of the first and second metering chamber means vary in their volumes,
- wherein at least one of the first and second metering chamber means are assigned to one another in parallel pairs, each pair being connected to an assigned reaction chamber so that the volumes of the sample liquid and dilution liquid which are contained in the first and second metering chamber means are transferred in separate parallel paths into the assigned reaction chambers and mixed, by which the sample liquid can be diluted with different dilution ratios.
