Sealing Film, 50 Sheets: 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. It is 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.The Sealing Film was developed with the assistance of a major cycler manufacturer for PCR applications. Not only does it offer low-autofluorescence but it will prevent vapor loss and is thermostable and functional from -70 °C to +95 °C. Certified RNAse, DNAse and DNA-free. DMSO resistant.Note: Performance may depend upon the specific collection/sample vessel used as well as the specific conditions to which it is subjected.
