In an early adventure, with my players in debt for a ship they had to make payments on to a local noble....and with a bum fuel purifier plant they had to raise MCr 1.5 to replace...
They ran into a situation where they had to identify a substance.
When I asked how they planned to do that, one of the players very arrogantly said, we should be able to run it through the mass spectrometer...
And I smiled and asked, "OK. Where ya gonna buy it?"
Suddenly uncertain of himself, he asked, "Wait! The ship didn't come with one?"
I answered, "The ship didn't come with bed linen. What makes you think there was a Mass Spec to start with? And, if there had been, who would empty the galley and take the bedding while leaving an expensive toy like that?"
If you want some basic ideas, watch a few seasons of NCIS and listen closely to the "forensic scientist chatter"
If you don't like that, use your imagination. Consider everything from basic lab gear (microscanners, Lab glassware, Electronic sensors, computer-integrated lab tools[rock substrate auto-slicer for microscopic study ]) to advanced specialized equipment like DNA analyzers, environmental scanners, Autonomous Expert-system Androids for remote investigation, Advanced Medical kits and even specialty devices integrated to suit tech. And, you can determine availability and cost from any of the game's editions.
Hell, my game is largely MT-based, but I use gear from both "every" variation of Traveller and other Role Playing Games.
I even look at D&D stuff and do my best to decide if it can be done as a piece of technology instead of magic.
