An app for intensive users who are willing to install it for a precise purpose. This native app allows completely independent operation and does not need a desktop in any way (as long as it is connected wirelessly, allowing workers to be free to work in a freezer room or clean room outside the lab). The app provides users with the ability to move, book in/out and dispose of samples, along with a very powerful audit facility to stock-check freezers. Using one of Pro-curo’s combined devices that include an integrated 2D barcode reader creates even greater efficiency gains because a technician doesn’t need to type in a sample number or figure out a current sample location. One simply selects “move samples” to scan one or 100 samples, then scans the rack, drawer, or box location barcode and the process is complete - along with full traceability of when/where/by whom this action was performed to be added securely to the central database. Data storage is not external cloud-based because of the sensitivity and security of the data.
