Claim:
A tissue infiltration apparatus for specimens present in cassettes carried by transport baskets, the tissue infiltration apparatus comprising: at least two liquid containers; a transport apparatus operable to transport at least two transport baskets in the tissue infiltration apparatus and deliver each transport basket to and from the liquid containers in a definable execution sequence, wherein a first of the at least two transport baskets has an initial execution sequence; at least one storage unit for storing at least one transport basket, wherein the storage unit does not contain liquid; and a control unit for controlling the tissue infiltration apparatus, wherein the control unit is configured to modify the initial execution sequence to create a modified execution sequence; whereby the control unit causes the transport apparatus to deliver the first transport basket from the at least two liquid containers to the at least one storage unit to store the first of the at least two transport baskets according to the modified execution sequence while the second of the at least two baskets is delivered to one of the at least two liquid containers such that the second of the at least two baskets overtakes the first of the at least two baskets in the definable execution sequence.
