A 36 µm soft non-permeable aluminum foil sealing film with strong medical-grade adhesive, AlumaSeal II sealing films eliminate the need for heat-sealing devices or mats during thermal cycling.

• Easily pierceable with single or multichannel pipettors and robotic probes
• Heat & cold resistant, recommended for temperatures from -80°C to 120°C
• Certified DNase-, RNase-, and nucleic-acid-free
• Excellent barrier properties, virtually no sample evaporation or drying

Each sealing film measures 82.6 x 142 mm and offers sufficient sealing area for all PCR plates. Length between the perforations with end tabs removed is 125.4 mm. Compared to other aluminum foils, AlumaSeal II has less tendency to roll back or itself when removing the backing paper and conforms well to the plate during application.
