Glossary of Terms and Instrument Options
Worktable
Working surface (or deck) of the pipetting instrument where objects (such as
microplates) are placed for access by the liquid handling arm (LiHa) or the
plate robot (RoMa).
Worktable Editor
Graphical representation of the pipetting instrument's worktable (deck). It
shows icons for the devices which are installed and the arrangement of the
carriers and labware.
The gray area in the Worktable Editor represents that part of the worktable
which can be accessed by the Liquid Handling Arm. This is called the
pipetting area. The real worktable is normally larger than this.
See Fig. 11-8 “Example worktable showing carriers, labware and labware
labels”, 11-20.
Worktable, initial
Graphical representation of the initial layout of the pipetting instrument’s
working surface (deck). When required by the script or process, Freedom
EVOware uses the plate robot (RoMa) to move labware during runtime to new
positions (carrier sites). However, carriers and devices always stay at the
same position.
XP and XLP dilutor
→ Dilutor
X slide
Rail across the top of the pipetting instrument which supports the robot arms
(→ LiHa, → MCA, → RoMa, → PnP). The robot arms move along the rail to
reach all of the X positions on the worktable.
Y-distance of wells
The spacing between adjacent wells in the rack in the Y direction (front to
back).
Z-Dispense
Tip height at which liquid is dispensed. It should be low enough to ensure that
no liquid drops can get into adjacent wells or tubes. See Fig. 9-13, 9-26.
Z-Max
Tip height which is very slightly above the lowest point of the well, tube or
container. It is the lowest position which the tip is allowed to reach without
touching the bottom. When searching for the liquid surface, the pipetting
instrument will search from Z-Start down to Z-Max. If the tip reaches Z-max
without finding liquid, the pipetting instrument reacts according to the
configured liquid level detection error mode. See Fig. 9-13, 9-26.
Z-Start
Tip height at which the liquid level detection (ILID) is switched on during
pipetting. For tubes and containers (troughs), choose Z-Start to be at least 1
mm below the rim but above the liquid surface. For microplates, choose Z-
Start to be at least 1 mm above the edge of the well.
Z-Start should be chosen as low as possible to ensure fast liquid level
detection. At the same time, Z-Start must be above the highest possible liquid
level in the well/tube to ensure that the liquid surface is found. See Fig. 9-
13, 9-26.
