VERTICAL FUNCTIONAL REACTION VESSEL

A reaction vessel for a vertical operating position geometrically bits into a standard receiving vessel providing an outer volume, for example a centrifuge tube, microplates and deep well plates. The reaction vessel including at least one upper opening with a seal element for reversible sealing for typical liquid handling techniques for filling, emptying mixing and gassing; at least one upper opening for pressure balancing and overrun; and a form stable body which forms at least one non capillary reaction cavity as an inner volume with at least one semipermeable membrane as a side wall. The at least one upper opening with the seal element for reversible sealing for standard liquid handling for filling, emptying, mixing and gassing leads through at least one capillary channel in the form stable body vertically into a lower portion of the reaction vessel and forms an opening at this location.
