These are the next generation films for classic thermal cycling applications consist of a 50 µm polyester film with a 41 µm layer of acrylic adhesive. Compared to the older films in the past, Opti-Seal PCR and Storage films offer better adhesion, reduced evaporation, longer end tabs for easier handling, and fewer tendencies 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.
Noted that Opti-Seal PCR and Storage Films are not pierceable with pipette tips or robotic probes are required for product recovery.
