What Does
PosID Mean?
PosID stands for positive identification, i.e. whenever necessary an identification
step for carriers or containers (tubes and microplates,) can be programmed in the
application software in order to ensure that the correct labware is processed.
The PosID can automatically scan barcodes on carriers and containers by means
of a built-in barcode laser scanner. Barcodes can be read on both the primary side
(e.g. sample tube), and the secondary side (e.g. microplates). To enable
identification with the PosID, all carriers and containers must be labeled with
barcodes.
How Does it
Work?
The PosID body runs past the carriers to scan the carrier ID barcode (through the
front aperture). With its gripper, the PosID pulls the carriers towards the rear of the
instrument (passing the barcode scanner) for barcode identification on containers
and then shifts the carriers back into operating position.
The barcode scanner is suspended in such a way that it can identify vertical and
horizontal aligned barcodes.
Before each container scan the PosID scans the alignment barcode on the
barcode flag, which is attached to the gripper, to verify that the barcode scanner
and the gripper are in the correct position. This improves identification security for
the containers.
