This transparent sealing tape consists of a 2.0 mil polyolefin film coated on one side with a pressure sensitive acrylate adhesive which does not interfere with cycle reactions. Ideal for reducing well-to-well contamination and/or spill over in sensitive PCR applications where the minimization of evaporation and vapor loss is critical. Not only does it offer low-autofluorescence but it will prevent vapor loss and is thermostable and functional from -70C to +95C. Manufactured RNAse, DNAse and DNA-free. DMSO resistant.
