Sealing films, tapes and foils are basic consumables common to most wet laboratory setting. Sealing films are designed to protect against oxidation, evaporation, and cross-contamination in cell cultures during processing, storage, and transport. Foils are utilized in multiple ways like covering labware containers and making weighing dishes or boats, while tapes and tags are used for packing and labeling purposes. We offer a wide range of sealing films, foils, and tapes for your research or clinical work from the best names in the business including Duraseal™, Parafilm®, AlumaSeal®, ThermalSeal®, and many more.
Sealing films are used for various applications including general incubation, cell culture, PCR multi-well plates, and storage. Our comprehensive portfolio allows you to choose from different types of sealing films with properties like heat sealability, pierceability, non-cytotoxicity, sterility, or compatibility with polypropylene (PP), polyethylene (PE), and polystyrene (PS), best suited for your application.
Choose from our wide selection of foils, available in different formats including sterile, heat-sealable, pierceable, and pre-cut for specific applications in your research laboratory. We offer aluminum foil which easily covers laboratory dishes and forms inexpensive liners for benchtops, drawers, and trays for easy cleanup in case of spill or contamination. Our Mini Bin™ aluminum foil is designed for easy use and minimal waste, as custom-sized pieces of foil can be easily created that are ideal for autoclaving, freezing, incubating, protecting labware, lining, sealing and general storage. ThermASeal Foil™ heat-sealable seal is a sterile, non-pierceable foil laminate that can be used for PCR applications, specifically with water thermal cyclers, for long term storage of solvents and other organics (including acids and alkaline). For storage and shipping of PCR samples and other compounds, we supply two heat sealable seal product variants, PierceASeal Foil™ (a pierceable foil laminate) and PeelASeal Foil™ (a non-pierceable seal). Our Scienceware® Super-Polyfoil™ wrap/cover sheet has a special thermoplastic polyester layer that blocks any pinhole development caused during autoclaving, incubation, and chemical laboratory implementations. To save your valuable time, we offer pre-cut, aseptic, RNase and DNase free Speedy-Foil® that meets the FDA requirements for direct contact with pharmaceuticals and can be used to cover common laboratory containers.
You can now choose from our comprehensive range of tapes used for labeling, insulating and sterilization in for your lab applications. Our general purpose, self-adhesive labeling tape can be written on with pen, pencil or permanent marker and remain effective at temperatures from -23 °C to +121 °C. We also offer silicone insulating tape shields against moisture, heat, and cold, even at extreme temperatures from -65 °C to 260 °C. In addition, our autoclave indicator tape, Sigmaware™, gives a positive indication of sterility after 15 minutes of exposure at 121 °C in a steam autoclave.
