It's been years since I've been in a chemistry lab, so I don't remember how they monitored inventory levels, but do they really just jot down amount used/remaining for each chemical? If that's the case, then I can certainly see value in the app. Just brainstorming, how feasible would it be to detect fluid levels/quantities using the phone's camera? A chemist can simply snap a photo of a vile and the rest is automagically taken care of. Or maybe you could at some point sell a line of viles/beakers/flasks/etc with level markers, volume indicators, and chemical labels that would work with your app. A little design feedback: I would show the product on the homepage. Right now you're just selling to me with words. And the weight of that typeface being used for that sub-header is really light.
