Why not make it so that a Medibot can only manufacture the reagent after it gets a decent quantity inside first, say 50 units? That makes it a little bit of work so that people can't just make it in chemistry in 10 seconds and stick it in for an easy round, while avoiding the hassle of refilling it.
