Modular measuring cell for measuring chemical and/or physical properties of a fluid

A modular measuring cell for analytical technology in bioprocess analysis comprising two or more successively arranged and interconnected individual modules, wherein the individual modules are each:

• configured as a flow-through measuring cell for a fluid including an inflow opening and an outflow opening, which are assigned to a first outer surface and a second outer surface of the individual module, respectively;
• include a flow channel having a measuring chamber between the inflow and outflow openings;
• include first connecting elements with an axisymmetrical arrangement on the first and second outer surfaces;
• and
• include at least one further opening configured to enable installation of a sensor in the measuring chamber, the sensor configured to measure chemical and/or physical properties of the fluid flowing through the measuring cell,
• wherein a uniform adapter is arranged between two successive individual modules, which adapter includes a fluid-connecting passage opening and is configured to connect the flow channels of the successive individual modules to form a main line channel,
• wherein the adapter includes a first outer surface and an opposing second outer surface, which include second connecting elements having an axisymmetrical arrangement, wherein the first and second connecting elements are complementary to each other, and
• wherein each individual module is configured to be connected with respect to an adjacent individual module by a predetermined number of orientations about an axis of symmetry.
