SealPlate® 50 µm thick polyester films minimize evaporation, prevent spillage and contamination between wells and provide a secure seal, not just a cover. Secure sealing of all wells eliminates edge effects in sensitive ELISA assays. SealPlate® films can also be used with tissue-culture plates for short-term storage, incubation, and containment of biohazards. SealPlate® films are non-pierceable. Each film measures 79.4 x 146 mm.
