In the application software, the following rack parameters for test tubes are predefined:
Test tube diameter, outside
Note: In the case of deviating parameters, these values must be adjusted in the applica-
tion software.
When using test tubes, pay attention to the following:
• In each rack, use test tubes of one size only. Tube height and diameter must be identi-
cal for all test tubes.
• Make sure that all test tubes are positioned correctly in the rack and touch the rack
bottom.
Z-travel
A carrier’s Z-travel is the Z-height above any obstacles that go with this carrier.
Z-dispense
Z-dispense is the Z-height from which liquid is dispensed from the air. It should be
adjusted to a height from which no droplets can fall into adjacent cavities.
Z-start
Z-start is the Z-height at which liquid detection is activated.
Z-start must be situated at least 1 mm below the cavity rim and above the liquid
level. The microplate, for which Z-start is defined 1 mm above the cavity rim, is an
exception to this rule.
Z-max
Z-max is the Z-height which lies as close as possible to the lowest cavity point with-
out touching the cavity bottom.
