VWR®, Adhesive PCR Film Seals
Supplier: VWR Collection
These heat resistant 74,9 µm thick films are designed for thermal cycling applications. Polypropylene films are not pierceable. For PCR applications, where piercing with pipette tips or robotic probes is required for product recovery, use aluminium foil films. For real-time PCR applications, where maximum optical clarity is required, use optically-clear polyester films.

VWR®, Adhesive PCR Foil Seals
Supplier: VWR Collection
These soft, non permeable 63,5 µm thick aluminium foils, with strong medical grade adhesive, eliminate the need for heat sealing devices or mats during thermal cycling. Compared to other aluminium foils, these foils have less tendency to roll back on themselves when removing the backing paper, and fit well to the plate during application.

VWR®, Black Film Seals for Fluorescence and Photoprotection
Supplier: VWR Collection
These films are 240 µm thick black vinyl with adhesive for use with 96-well, 384-well and 1536-well black microplates. They fit within the edges of raised rim plates and may be applied to either the plate top or bottom. The light blocking and absorbing properties of these films make them ideal for reducing stray light and crosstalk in fluorescence applications and for protecting light-sensitive samples in storage.

VWR®, White Films for Luminescence and Microscopy
Supplier: VWR Collection
These films are 240 µm thick white vinyl with adhesive, for use with white microplates. Light reflective properties of the film, when used to seal clear bottom plates, maximise the sensitivity of bioluminescence and chemiluminescence assays in bottom-reading luminometers. White films have also been used as a backing matrix for microscopy of punch-out samples from filter plates.
