These unique seals combine the strong sealing integrity of our PCR Seal with improved optical properties, thanks to the 96 adhesive-free windows. The seal is made of a durably transparent polyester film, and a strong adhesive is applied across the seal, apart from the 96 round windows. The Optically Clear Windowed qPCR Seal is recommended for qPCR and other optical applications, such as fluorescence or colorimetric measurements.
For all adhesive seals, the best sealing results are achieved using the hand held Adhesive Seal Roller (4ti-0502).
