ThermalSeal® RTS™ sealing films are 50µm polyolefin films with 50µm inert encapsulated silicone adhesive. They are optically clear, with low autofluorescence, and are especially suited for real-time qPCR, storage, and protein crystallization applications. The encapsulated silicone adhesive is non-tacky until pressed against the sealing surface, at which time adhesive is released only in sealing areas to form the strongest available heat-resistant seal around each well on the plate. Adhesive on non-sealing areas of the film, such as directly over sample wells, remains encapsulated and inert. One roll seals up to 540 microplates.

Features high optical clarity, minimal to no autofluorescence, chemically inert; no extractables except at extreme pH, and DMSO resistant for HTS. Heat resistant; recommended for temperatures from -80 °C to +105 °C
