SealPlate® 50 µm thickness polyester sealing 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 sealing films can also be used with tissue-culture plates for short-term storage, incubation, and containment of biohazards. SealPlate sealing films are non-pierceable. Each SealPlate sealing film measures 79.4 x 146.1 mm. ThinSealTM polyester sealing films are just 25 µm thick, clearer and marginally peirceable with single-channel pipettes for sample recovery. ThinSeal sealing film dimensions are 79.4 x 141.0 mm. functional temperature range from -40°C to +120°C
