ThinSealTM polyester sealing films are just 25 µm thick. Each SealPlate sealing film measures 79.4 x 146.1 mm. , clearer and marginally peirceable with single-channel pipettes for sample recovery. -Functional temperature range from -40°C to +120°C -Available sterile and non-sterile SealPlate® 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.
