7.3 Bar code reader
7.3.1 Sample input bar code reader
The QIAsymphony SP has an integrated bar code reader that can read bar codes on tube carriers
and sample tubes. A default tube type must be defined for each type of insert used. The tube type
is automatically assigned when the insert bar code is read.
Primary tubes can be labeled with bar codes.
The integrated bar code reader of the “Sample” drawer scans:

The position bar codes of the tube carriers.

The bar code labels on sample tubes.
Each slot in a tube carrier has a bar code at the back of the slot. If the position is empty, the bar
code at the back of the slot can be read by the bar code reader. This enables the QIAsymphony
SP to detect which positions in the tube carrier contain a tube and which are empty.
If you are using sample tubes that are not labeled with bar codes, tubes containing small volumes
of liquid or clear liquids may not be detected. In this case, use a blank bar code label to enable
detection of the sample tube. For more information, refer to the
QIAsymphony SP/AS User
Manual — General Description .
The scanned sample ID lists can be manually corrected and assigned into batches based on
existing sample information or following user input. For more information, refer to the
QIAsymphony SP/AS User Manual — General Description .
Four tube carriers are available for use with sample tubes. In some protocols, samples may also
be processed with positive or negative controls. A fifth tube carrier accommodates tubes
containing internal controls that will be added to the samples.
7.3.2 Reagents and consumables 2D bar code reader
As part of the inventory scan of the “Reagents and Consumables” drawer, the 2D bar code
camera on the QIAsymphony SP identifies the different reagents in the reagent cartridge and also
checks that the correct reagent cartridge has been loaded. The 2D bar code reader is attached to
the robotic arm.
