I would think that if you were going to do a lot of alchemy, you might want to assemble a complete "lab," with not just your alchemy equipment, but also scales, an hour glass, and various vials and jugs.
Yes, I always do that. Some times I litter the floor with ingredients and 'failed' potionsm 'broken' apparatuses, it makes me feel completely insane.
And in every room of my house(s), there is an hourglass, what use is it if you don't know what time it is, as I like to think they run for 24 hours.
