PCR Sealing Film is a type of polyethylene film that is used to form a tight seal around the edges of a PCR plate, tube or container. PakGent PCR sealer is designed to be used in PCR applications such as DNA extraction, amplification, and sequencing. The PCR plate film provides a hermetic seal, blocking out air and moisture, thus helping to preserve the integrity of the sample. PCR plate sealing film is also used to protect the sample from contamination, reduce evaporation, and increase the efficiency of the PCR reactions. PCR Sealing Film is available in a variety of thicknesses and sizes to suit the needs of the application.
