1.5ml Eppendorf tubes are sterile snap-top tubes that are used for lots of small volume molecular biology applications. We buy them in bulk and autoclave them in recycled tip boxes (see pic). change whatever
If there aren't any in a box on your bench, more are stocked in the rack in between Mark and Monique's desk. These are sterile until you open them so keep the bag or box closed when not in use.
These are not RNAse free for RNA work; we have special ones for that ask someone if you need those!
