Porvair Sciences Ultraseal™ Peel Seal DMSO Foil - 78 mm Sterile Roll SF05078SR

Ultraseal Peel Seal DMSO Foil is a DMSO‑resistant foil laminate designed to provide a liquid barrier seal for microplate wells. Supplied as a sterile 78 mm width roll, the seal is peelable and intended for low‑temperature and ambient compound storage, including long‑term storage of samples in dimethyl sulfoxide (DMSO) and organic solvents. Access is by peeling or by piercing with a blade or needle where required, and the seal is compatible with polypropylene and forms an excellent seal to cyclic olefin copolymer (COC) plates.
