Running a protocol to unload labware from a storage device  
You can run a protocol to unload a batch of labware from storage devices. During the run, the system will automatically track the labware (with or without barcodes) and update the inventory database.
To run a protocol to remove labware from a storage device:
1 Ensure that one or more labware racks are empty on the BenchCel stackers before running the protocol.
2 Write a protocol that contains the following:
Unload task to remove the labware from the storage device.
Upstack task to move the labware into an available BenchCel stacker.
 
3 Make sure that the Upstack task is configured to use the appropriate stacker.
 
4 In the Inventory Editor, identify the labware that you want to move:
a Click the Unload task.
b Click Storage Load.
c Click the Locations tab.
d Click Edit location groups to open the Inventory Editor.
e Click the Inventory Management tab. Note the device, cassette and slot numbers for the labware that you want to remove.
 
5 If necessary, create a location group in the Inventory Editor that contains the labware you want to remove. See Creating and managing location groups for instructions.
Save the changes and confirm it by making sure it is listed in the Available locations area on the Locations tab of the Load Task Parameters toolbar.
6 Drag the location group into the Assigned locations area.
 
7 Compile the protocol and resolve any error messages.
8 Run the protocol (click Start).
9 In the Run Configuration dialog box that appears, specify the number of times to run the protocol. Type a number that is equal to or less than the number of labware you want to unload from the storage device.
10 Click Finish. The protocol run starts.
11 To confirm that the labware are removed from the inventory database, open the Inventory Editor. See Opening the Inventory Editor.
Removing selected labware information from the database 
You can remove individual labware entries in the inventory database. Use this method if you want to remove labware entries under the following scenarios:
Instead of running a protocol, you can unload individual labware in the storage device by hand, and then use the Inventory Editor to update the inventory database.
A batch of labware was already removed from storage devices, but you need to remove the corresponding entries from the inventory database.
To remove labware entries from the database:
1 Open the Inventory Editor. See Opening the Inventory Editor.
2 Click the Inventory Management tab.
3 Select the labware entries you want to delete, and then click Delete selected entries from inventory.
If you are deleting a batch of labware entries, you can CTRL+click to select non-contiguous entries, or SHIFT+click to select contiguous entries.
 
4 Make sure you physically unload the labware from the storage device so that the storage state of the device matches the information in the database.
5 Storage devices that have their own barcode readers. To validate the changes, in the Inventory Editor Inventory Management tab, click Re-inventory selected locations. For instructions, see Reinventorying the labware inventory.
