Ideal for the storage of Biological materials at extremely low temperatures, our polypropylene tube with high density polyethylene cap has an incredibly secure 2 turn closure that includes an external thread. Specifically designed to remove the risk of trapping samples on the inner wall. The difference in hardness between the tube and cap coupled with the caps molded in sealing ring forms a leak resistant seal even at extremely low temperatures.
