A 1.4mil soft, non-permeable aluminum foil with strong medical-grade adhesive, AlumaSeal® II™ film eliminates the need for heat-sealing devices or mats during thermal cycling. Compared to other aluminum foils, AlumaSeal® II™ has less tendency to roll back on itself when removing the backing paper and conforms well to the plate during application.

AlumaSeal® II™ films exhibit excellent barrier properties, with virtually no sample evaporation or drying and are also easily pierceable with single or multichannel pipettors and robotic probes. They are heat & cold resistant, with a functional temperature range from -80°C to +120°C.
