To guarantee random access to sample carriers, only the inner tube positions should be
used. The number of blank positions to be used for the different instrument configurations is
listed in the following table:

The 16-channel Microlab STAR is intended as a batch-type processor, i.e., random access to
all positions is not possible. By contrast with an 8-channel Microlab STAR, the methods for a
16-channel instrument should be set up in such a way that all positions are processed in
batches of at least 8 (or better 16, to optimize the pipetting speed) with 8 (or 16)
simultaneous aspirations or dispenses at identical x-coordinates (see section 8.9 for more).

Different pipetting heads are available for the different volume ranges:
a) from less than 1 µl to 300 µl (for the use of low volume tips = 10 µl, and standard tips
= 300 µl), or
b) from 5 µl to 1000 µl (for the use of standard tips = 300 µl, and high volume tips =
1000 µl).
Currently, a mixing of high and low volume channels on one and the same instrument is not
feasible.
