| 12 | | * Two QIAcube instruments are used, called "C" and "A":[[BR]]a. For 1-12 specimens, instrument "C" is used.[[BR]]b. For 13-24 specimens, the samples are distributed as evenly as possible between the two instruments.[[BR]]c. For each QIAcube, the samples are allocated positions according to the QIAcube placement scheme, in order to ensure stability of the centrifuge.[[BR]]d. Originally, 1 and 11 samples are not allowed in a QIAcube run, since they cannot be distributed so as to result in acceptable stability of the centrifuge. However, they will be allowed here, if a counterbalance blank vial filled with water is added, to ensure stability. A reminder note should be displayed to minimize the risk, that the counterbalance vial is forgotten.[[BR]]e. A generalized QIAcube position will be used in the form, consisting of a QIAcube instrument prefix letter "C" or "A" followed by the traditional position number in the instrument.[[BR]]f. The generalized QIAcube position will be stored as two annotations for an extract; the original QIAcube position number and a QIAcube instrument prefix. |
| | 12 | * Two QIAcube instruments are used, a primary and a secondary one. If only one instrument is needed, the primary is used. The instruments are specified by a prefix consisting of an uppercase letter. It should be possible to modify the prefixes for the primary and secondary QIAcubes, since different physical instruments might be used. The default prefixes for the primary and secondary instruments are "C" and "A", respectively:[[BR]]a. For 1-12 specimens, the primary instrument is used.[[BR]]b. For 13-24 specimens, the samples are distributed as evenly as possible between the two instruments.[[BR]]c.
