Sealing films are essential laboratory consumables used to securely cover microplates, PCR plates, and other sample containers. These films, often made of optically clear materials like polyester or polypropylene, create a tight, contamination-resistant seal over sample wells. They are widely used in life sciences, genomics, and drug discovery research to prevent sample evaporation, minimize cross-contamination, and protect samples from environmental contaminants. Sealing films may come in various formats, including adhesive films, heat-sealing films, and pierceable films, offering options for different applications and automation needs. Their ease of use and ability to maintain sample integrity make them indispensable in modern laboratories.
