Charles River Labs going to space?

Medgadget covers Astronauts getting hand held microorganism detectors for use in space. Interestingly enough the picture shown and the source pictures is a Charles River Laboratory Endosafe PTS. It looks like the have the older version of what is being sold currently. That sure is a lot of horn tooting from NASA for buying a piece of off the shelf equipment. In fact, the description sounds exactly like how the Endosafe PTS works right down to the crabs and only detecting gram negative bacteria, they even call the thing LOCAD PTS. Maybe the modified it for use in space or gave it more features?
