10 - Configuring Liquid Classes
MCA384 Liquid Classes
Use Liquid Detection
The MCA384 does not support liquid level detection for dispensing directly. If
you want to use a liquid class for the MCA384 which specifies liquid level
detection, the liquid level must be emulated using a special variable (see
14.1.4.14 “RACK_VOLUME_x”, 14-7). Check this checkbox if you want to
activate the emulated liquid level detection. Liquid level detection can be used
e.g. to ensure minimal tip contamination by limiting the tip immersion depth.
For Freedom EVOware Plus, see 14.1.4 “Pre-Defined Variables”, 14-4 for
information on accessing the current value of this pre-defined variable in
another script.
Dispense Position
Specify the Z-position and the Z-offset of the tips when dispensing. A positive
value for the offset lowers the tips.
If you choose a dispense position with tracking, the tips move upwards as the
liquid level rises in the wells during dispensing. This option can be used e.g. to
ensure minimal tip contamination by limiting the tip immersion depth.
You can also choose the X-position when dispensing as follows:
– Center: as specified for the labware which is used
– Left: left of center; the offset is specified with X or Y offset while pipetting
for the labware which is used
– Right: right of center; the offset is specified with X or Y offset while
pipetting for the labware which is used
– Left / Right: left of center for odd columns, right of center for even
columns; the offset is specified with X or Y offset while pipetting for the
labware which is used
– Right / Left: right of center for odd columns, left of center for even
columns; the offset is specified with X or Y offset while pipetting for the
labware which is used
You can also choose the Y-position when dispensing as follows:
– Center: as specified for the labware which is used
– Rear: rear of center; the offset is specified with X or Y offset while pipetting
for the labware which is used
– Front: front of center; the offset is specified with X or Y offset while
pipetting for the labware which is used
– Rear / Front: rear of center for odd columns, front of center for even
columns; the offset is specified with X or Y offset while pipetting for the
labware which is used
– Front / Rear: front of center for odd columns, rear of center for even
columns; the offset is specified with X or Y offset while pipetting for the
labware which is used
By combining an X offset and a Y offset, there are nine possible pipetting
positions (including the center position with no offsets).
