Sealing device for thermal cycling vessels

摘要

A sheet of material seals vessels for biochemical reactions which undergo thermal cycling, and comprises a multilayer composite sheet which is placed over the openings of one or more reaction vessels. The multilayer composite sheet material has at least two layers, one layer providing strength and integrity to the material and the second layer being relatively thick comprising a deformable substance with a tacky surface to contact and seal vessels for biochemical reactions.
