BrightMax™ sealing films are 203µm thick white vinyl films with 37µm acrylic adhesive for use with white microplates. The sealing films may be applied to either the top or bottom of the plate. A split backing aids in applying the sealing film properly. The light-reflective properties of BrightMax™ plate-sealing films on clear-bottom plates maximize sensitivity of bioluminescence and chemiluminscence assays in bottom-reading luminometers.

White films also have application as a backing matrix for microscopy of punchout samples from filter plates, for example in ELISPOT assays. Dimensions are 76.2mm x 116.0mm with no end tabs. A backing split singly on the long dimension aids in applying film to plates. Recommended temperature range: -40 °C to +80 °C.
