You will be headed to the Tanaris desert, testing the tissue consistency of the basilisks, scorpids, and hyena native there. Obtain tissue samples and use them with the testing kit in tow; expect a chunk of the samples to fail. I need eight acceptable samples of each creature type.
In addition, the goblins of Gadgetzan have a power source that must be used with this kind of modified kit. Speak to Chief Engineer Bilgewhizzle and acquire one for the kit.
