Parallel cell processing method and facility

A system for parallel processing of a plurality of biological cellular samples comprising:

• a first processing unit (U1) comprising a plurality of processing stations (P1/1 to P1/n), wherein the first processing unit (U1) is configured for processing in parallel a plurality of cellular samples (S1 to Sn) on the processing stations (P1/1 to P1/n) to produce a first plurality of processed cellular samples (S1/1 to Sn/1);
• a second processing unit (U2) containing a plurality of processing stations (P2/1 to P2/n), wherein the said first plurality of processed cellular samples (S1/1 to Sn/1) are configured to be transferred to the second processing unit (U2) and processed in parallel to produce a second plurality of processed cellular samples (S1/2 to Sn/2);
• and
• wherein the system is configured to vary at least one processing instruction between at least two of the processing stations (P1/1 to P1/n) of the first processing unit (U1) and/or vary at least one processing instruction between at least two of the processing stations (P2/1 to P2/n) of the second processing unit (U2);
• and wherein each of the plurality of processing stations of the first processing unit (U1) and/or the second processing unit (U2) in which the at least one processing instruction is varied is configured to carry out cell culture or cell expansion.
