Two of the most useful tools in biology are also some of the simplest and are just things that need to warm up to a particular temperature and stay there. Today we're building two such devices, an incubator, and a heat block. Incubators keep their contents at a nice even temperature to speed up the growth of organisms. Heat blocks are dense, dry, heat sources for heating reactions to specific temperatures, often far higher than an incubator will ever go. Heat blocks are used during ligations, transformations, restriction digests and more. Best of all heat blocks are temperature regulated so there's no need to babysit them the way you do with a water bath. Probably the best part of this design is that it uses such readily available materials that it can be adapted for whatever vaguely warm container applications you'll have, like building bioreactors, which we'll explore in future videos.
