Zero-G crystalline chips were a type of cargo avaliable during the existence of the Alliance to Restore the Republic. A Corellian Engineering Corporation HT-2200 medium freighter was capable of carrying both zero-G crystalline chips and cryogenic bio-samples at the same time due to the fact it contained four separate cargo bays, each of which could be programmed for different environmental settings.
Behind the scenes
Zero-G crystalline chips were first mentioned in 1995 in the article "A Buyer's Guide to Alternative Starships," which was published in the fifth issue of the Star Wars Adventure Journal series of supplemental books for Star Wars: The Roleplaying Game by West End Games. The article was written by Stephen Luminati.
