ThermalSeal A™ (Advanced) sealing films are an advanced version of our classic ThermalSeal^® sealing films for PCR. (Mfgr #TSA-100).

ThermalSeal A films consist of 50µm thick clear polypropylene with a thicker 50 µm layer of a stronger adhesive formulated for improved protection against evaporation and leakage during thermal cycling. Intended for non-real-time PCR applications, ThermalSeal A films are designed to fit inside the edge of raised-rim PCR plates (although suitable for all plates) and provide more secure sealing of all wells because the center of the film does not extend over the plate rim.

Two end tabs allow for easy positioning of the film on the plate but are perforated for easy removal if necessary. Each film measures 77.8 x 135.5 mm overall. Length between the perforations wth end tabs removed is 118.1 mm. Each package of ThermalSeal A films includes one sealing paddle for ensuring a firm seal, also compatible with raised-rim plates.
