Porvair Sciences Ultraseal™ Gas Perm Seal - 78 mm Trial Roll SF10078TR

Ultraseal™ Gas Perm Seal is a gas-permeable, opaque non-woven heat-seal roll designed for short-term incubation and storage applications that require gas exchange, such as cell culture, seed and insect storage. The product is supplied as a 78 mm trial roll in a roll format and provides a porous barrier to solid contamination while permitting gas flow; it can be peeled or pierced for sample access and is intended for use with heat sealing. The seal is compatible with polypropylene and polystyrene plates and is suitable for overnight incubations and similar laboratory workflows.
