ThermalSeal? A™ is a 2 mil (50um) heat-resistant polypropylene film designed for thermal cycling applications. ThermalSeal? A™ films are now produced with a slightly stronger adhesive than the original product for better adherence to plates. Each film measures 3.083 x 4.65 inches and offers sufficient sealing area for all PCR plates. Certified DNase, RNase and nucleic acid free.

ThermalSeal? films are not pierceable. For applications where piercing with pipet tips or robotic probes is required for product recovery, see AlumaSeal II™ films. For real-time PCR applications where maximum optical clarity is required, see ThermalSeal RT and RTS.
