17.7 Configuring the Waste Option of the Te-Stack in
Freedom EVOware Plus
The following describes how to configure the double Te-Stack with the Waste
option (waste chute) in Freedom EVOware Plus in order to achieve the following:
• Fetch labware from tower 2 (front Te-Stack)
• Return labware to tower 4 (front Te-Stack)
• Fetch DITI racks with fresh DITIs from towers 1 and 3 (rear Te-Stack)
• Return empty DITI racks to the rear Te-Stack, whereupon they will be
discarded using the waste chute.
See Fig. 9-16, 9-43 for information on the default tower configuration (tower
numbers) for a double Te-Stack. The Waste option for the Te-Stack is mainly
intended for discarding empty DITI racks.
In this example, before the process starts, tower 2 should contain labware, tower
4 should be empty and towers 1 and 3 should both be filled with fresh DITI racks.
Note: The following description applies to the double Te-Stack right (i.e. the Te-
Stack is fitted on the right side of the worktable). The Te-Stack Left is a mirror
image of the Te-Stack right. The following description is only relevant for Freedom
EVOware Plus.
A double Te-Stack has four towers and two RoMa transfer positions. The default
position layout of the Te-Stack (2,2,50) configures the Te-Stack device carrier as a
two site carrier and the double Te-Stack is configured as as a single Freedom
EVOware device. For this example, it is necessary to subdivide the double Te-
Stack into two separate devices. This is because we want to configure the rear
towers to function differently to the front towers.
Proceed as follows:
Te-Stack Rear
Duplicate the device carrier “Te-Stack Right” and assign a meaningful name, e.g.
“Te-Stack Rear”.
Set the position layout to 2,1,25 (each tower normally holds 25 DITI racks; adjust
this value if necessary to suit the height of your DITI racks).
Click Attributes, add the attribute WasteLocation and set the value to “1”. This
activates the Waste option for the Te-Stack.
Check that Allowed labware includes your DITI racks.
Create carrier for the worktable
Duplicate the device carrier “Te-Stack Right” and assign a meaningful name, e.g.
“Te-Stack Worktable”.
Uncheck Carrier is device. This allows you to put the carrier on the worktable.
Set the position layout to 1,2,1 (two site worktable carrier)
Click Attributes, and set Allowed Robots to “Te-Stacker” (the call name of the Te-
Stack driver).
Check that Allowed labware includes your DITI racks and microplates.
Put the new carrier on the worktable.
