Featuring Extra Strong Adhesive !
These improved films for classic thermal cycling applications consist of a 50 µm polyester film with a 41 µm layer of acrylic adhesive for extra strength. 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 for raise-rim plates, Cat.#ST-4018.) ThermalSeal 2 sealing films are not pierceable. For applications where piercing with pipet tips or robotic probes is required for product recovery, see AlumaSeal® sealing films. For real-time PCR applications where maximum optical clarity is required, see ThermalSeal RT and Thermal RTS sealing films.

• Heat resistant, recommended for temperatures from -40 °C to +120 °C
• 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

ThermalSeal®, a 50 µm heat-resistant polypropylene sealing film, is designed for thermal cycling applications. (Not recommended for PCR plates with narrow or irregular sealing surfaces: AlumaSeal®, ThermalSeal A™, or ThermalSeal RT™ series films are better in such instances.) Each sealing film measures 79.4 x 135.1 mm and offers sufficient sealing area for all PCR plates. Length between the perforations with end tabs removed is 123.1 mm. ThermalSeal® sealing films are not pierceable. For applications where piercing with pipet tips or robotic probes is required for product recovery, see AlumaSeal II™ sealing films. For real-time PCR applications where maximum optical clarity is required, see our ThermalSeal RT™ and ThermalSeal RT2RR™ sealing films.
