Safarina: After a galley reorganizing I'm left with this very question and think the test tubes are a great idea (although I am concerned about breakage and capacity). My local hobby shop has "regular" test tubes but your pictures rack looks the best. Where did you find it/them?
PS - we don't miss the colder wx up there :-).
That picture is one I pulled off the net.. notice the dean and delucca sign... must have cost a wad...
I would go to a science supply. I know that there are sturdy plastic tubes available, but I like glass so when I change flavours the last occupant does not linger. Some of mine have screw tops, which I really like.
I have broken one once in a while, but not usually when they are stored. more often when I set one down where there isn't a raised edge and it ROLLS off the surface! The tube rack is good that way as you can stick them back in quick.
The tubes come in lots of sizes, mine are mostly 6"
I also use containers like this that I have emptied and refilled
I use a pill container as well for stuff I only carry a small amount of at a time
The pill container has no shalker option, but the 4 compartment container might be rigged with shakers easily.
Can you tell I use LOTS of herbs and spices!
