Maybe you could get your hands on some spent reagent bottles, or even just photos of them. Reset the system's memory in between uses if it requires new bottles each time.
Hacking the controller could be challenging if it's been deliberately hardened.
Heads up: it looks like they have the expiration date embedded in the first barcode and one of the pictured reagents is expired. Have you been able to set the system clock?
I'm aware of the expiration date, but haven't been able to understand the embedding or how the pairs of codes may be "hash validated" in some way, which means that this is a one time use for me unless I can either generate them or access the nvram on the system.
