How to Build a Freeze Dryer

Freeze dryers are best known for the fun food items they can be used to make like astronaut icecream, but they're actually really useful tools. From ideal sample preservation, to the preparation of useful cryogels, freeze dryers are used all throughout science. As machines go, they're actually really simple with only a few parts, so in this video I demonstrate how to make a freeze dryer in an afternoon.
