Measuring device and method for quantitative photometric detection of biomolecules in the low density region (low - density - biochips)

摘要

Measuring apparatus for automated quantitative photometric detection of biomolecules in the low density region, comprisinga measuring cassette (9) consisting of a transparent cassette housing (19), in which a measurement chamber (20), in which a low density biochip (14) with a provided with functionalized reaction areas glass - or plastic support can be inserted, an upper barrel chamber (21), an insertion opening (15) for the sample to be analysed (16) or samples, a sample delivery (22) with sample filter (23) which, with a sample conduit (24) for measuring chamber (20) is connected, a chamber (25), into which a storage container (26) with a reaction solution of a color-reactive marker can be inserted, and an activation of the plunger (27) to the opening of the storage container, a feed line for the reaction solution of color-reactive marker from the storage container for the measurement chamber, at least one supply line connection (28) and a feed line for a first auxiliary solution, at least a discharge line and a discharge connection (29) for waste solutions, a mixing device (30) for the homogenization of the sample (16) and the solutions mentioned in the measuring chamber (20) and..
