The invention relates to a fluid analyzer (20), in particular, a fluid analyzer for use in microfluid analysis, preferably for use in bioanalysis. The fluid analyzer (20) comprises a sturdy base (28,38) on which instrumentation modules (21,22,24,27) are rigidly mounted, said instrumentation modules include an analysis device (41) for conducting fluid analyses which is preferably configured in the form of a microfluidic chip (41), and a handling device (32), by means of which a storage device, in particular, a well plate (43), incorporating wells for accommodating fluids may be repositioned from a first position to a second position, in which a transport of the fluids from the wells to the analysis device is possible. Another instrumentation module (24) in the form of a device that is also rigidly attached to the base (28) is provided for the purpose of adding fluids to, and/or extracting fluids from, the wells of the storage device (33) and/or adding fluids to, and/or extracting fluids from, the analysis device. It is also provided that a first section or part of that instrumentation modules is arranged on one side of the base (28) and that a second section or part thereof is arranged on the opposite side of the base (28).
