Better adhesion; reduced evaporation Longer end tabs for easier handling Does not tear during removal from the plate Easier to apply than aluminum foils, no tendency to roll back Certified DNase-, RNase-, and nucleic-acid-free

These improved films for classic thermal cycling applications consist of a 50 µm polyester film with a 41 µm layer of acrylic adhesive. Compared to the original ThermalSeal films (below), ThermalSeal 2 films offer better adhesion, reduced evaporation, longer end tabs for easier handling, and less tendency to tear during removal from the plate. Each sealing film measures 79.4 x 139.7 mm and offers sufficient sealing area for all PCR plates. Length between the perforations with end tabs removed is 125.1 mm. (Not recommended for raised-rim plates; see ThermalSeal A films below.) ThermalSeal 2 sealing films are not pierceable.
