Very nice!
Most of my mixing stuff is in an organiser/tackle type plastic box which means digging around in the concentrates because I can't see all the labels. I've got them sectioned off into fruits/desserts etc but it's still a pain.
Something I haven't used is my scales, if I'm measuring in syringes then there doesn't seem much point in weighing it too. Are you taking more than you need in the syringe, weighing it then putting some back in the bottle?
Where did you get the beakers? I found a site, put loads of stuff in the cart then it all disappeared and I thought 'well, I'm not doing all that again!'
