Excel Scientific Microplate Sealing Films

Microplate sealing films protect samples during assay processing, incubation, and storage.  Films are available in a variety of materials, adhesives, and configurations tailored to the specific application.  


ThermalSeal® films effectively minimize evaporation during thermal cycling and storage. Seals are engineered and produced to be RNase, DNase, DNA, & PCR inhibitor free. High optical clarity designs are available for qPCR.
