1) At first glance, I'm having trouble discerning what this might be used for or who its targeted to. Every discipline has different terminology, so I imagine what might work for Chemists might not work for Engineers. In our lab, we didn't have very many chemicals, but we had certain instruments setup with finite lifetime values.
2) Also at first glance, I thought this was a lab notebook replacement or supplement. Now that would have been awesome. Going back over my _many_ pages of notes over the years was a pain in the ass, especially when it came down to writing proposals and papers. I'm sure there is a huge opportunity in digitizing this to make lab notes searchable, reference-able, more organized, and even more secure.
3) To reach students, I would suggest to hitting up large conferences. If you're based in SF you're in luck because most of the big conferences my colleagues and I attended were in SF, NY, or Boston.
