- an activation unit is part of the micro bioreactor arrangement.
- the activation unit is on the
- Inserted unit and has numerous pumps that are connected to the areas formed by the inserts, namely via supply channels, which allow a fluid or nutrient transport between the two areas.
- microtiter plate individual cell culturing areas are observable through the underside of the microtiter plate and can be used simultaneously through the upper opening also in automatic pipetting systems and in standard analytical equipment (e.g., fluorescence microplate readers). It is thus the complete compatibility with standardized microtiter plates achieved, incl. all handling and analysis options.
- each of the inserts of the insert unit has a microstructured Formkör which is arranged parallel to the bottom surface of the microtiter plate and a settlement framework for cell cultures willing- provides.

- a modified embodiment is characterized in that at least one, preferably several of the inserts have at least two microstructured shaped bodies which are positioned parallel to one another and axially spaced from one another.
- Frame elements or the like is covered. This allows the optical observation of the substances or cell cultures on the moldings through the bottom surface, what preference, conventional inverse microscopes can be used.
- the microbioreactor arrangement according to the invention can therefore be clamped in existing observation arrangements such as a conventional microtiter plate in order to perform the observations.
- a distribution channel system is formed in the activation unit, via which the plurality of pumps are supplied with compressed air to perform the pumping operation.
- all pumps are driven in parallel, so that in each well diesel ben flow conditions prevail.
- the pumps transport a nutrient solution to supply the cell cultures that are located on the moldings of the inserts.
- the pumps can also be driven individually or in groups, for which a targeted control, for example by switching valves, which may be an integral part of the activation unit, is possible.
- An advantageous embodiment is characterized in that the insert unit comprises a sealing structure.
- the cell culture open area is cylindrically shaped and coaxially positioned in the associated well.
- the cover unit is provided above the open areas with a central opening through which substances can be supplied by means of a pipette.
- the closed area can also be arranged cylindrically and coaxially or be inserted in the open area in the form of tubes or capillaries.
- the two areas are preferably formed on the sealing structure, inserted into this or formed integrally with the sealing structure.
- the sealing structure extends substantially in the plane of the microtiter plate and lies flat on this surface.
- the insert unit comprises a supply channel system, which with each of their
- Inserts is coupled to allow the supply and removal of a nutrient solution to the inserts.
- the insert unit can be composed of several sub-layers to form the required cavities.
- the micro bioreactor assembly further comprises a cover plate which is mounted on the activation unit to close the Mikrobioreak gate assembly upwards.
- the cover plate can in this case be removed if necessary, for example to make the central openings in the inserts accessible.
