            Product Information
            Applications
            Eppendorf PCR films and foils include heat seals, self-adhesive seals, sealing mats, and plate lids. These provide effective and airtight plate seals to help protect your samples during assays like PCR, and transport and storage.

            PCR plate seals that won’t let you down


            When working with PCR plates, you need sealing solutions that won’t let you down. Experience the exceptional sealing power of Eppendorf films and foils, which offer:
            Very low evaporation rates - So you can maintain high accuracy and viability.
            High transparency – Our highly transparent films minimize fluorescence interference, allowing for accurate signal detection in real-time PCR (qPCR) assays.
            Heat resistance - Our films don’t shrink or curl when heated, making them well-suited for PCR and qPCR assays.
            Good marking properties – You can easily write on our films and foils with standard lab markers, making sample tracking simple and error-free.
            High purity – Our films and foils are certified PCR clean, avoiding sample contamination and inhibitory effects on your assays.
            Ergonomics – Two end tabs on each film and foil make positioning easy and precise, avoiding any contact with the sealing area.

            Do Eppendorf sealing options have chemical resistance?


            Our PCR plate seals offer excellent chemical resistance and have been tested for resistance to a variety of common laboratory substances.
            For more information, see Userguide 043 (Investigation of the chemical resistance of sealing systems for PCR plates, deepwell plates and microplates)

            What Eppendorf PCR plate seal options are available?


            Eppendorf offers a range of different sealing systems for lab plates. Available options include:

            Adhesive films or foils


            • Adhesive films or foils are glued the plate surface.
            • Simple handling; however, diligent and equal pressure are necessary to ensure good protection from evaporation.
            • Possible influence of the adhesive on the sample has to be taken into consideration.
            • Optimal adhesion only at PCR temperatures and should not be used for storage applications.

            Sealing mats


            • Reusable mats made from an elastomer.
            • The plate can be opened and re-sealed at any time.
            • The mat needs to be compatible with the plate (round/square wells).

            Plate lids


            • Reusable transparent lid made from polystyrene.
            • Simplest and fastest closure option.
            • Mainly used as a temporary cover and for short incubations, since protection from evaporation is limited compared to other sealing options.

            PCR Film and Foil (self-adhesive)Heat-sealing foils and films (requires a plate sealer)


            • Heat-sealed foils and films are welded to the plates using a heat-sealing device.
            • Very secure and effective heat seal.
            • Only suitable for plates made from polypropylene or similar materials (including Eppendorf twin.tec® PCR Plates)
            • A raised rim around the individual wells is required for heat seals.

            Which sealing system should I choose for my PCR plates?


            PCR sealing film or foil?


            The right sealing option will highly depend on your intended application. The first choice you should make is whether foils or films are most suitable. In general, foils are well-suited for light-sensitive samples. Foils can also be easily pierced, meaning your samples can be transferred via a needle or automated system. On the other hand, films are a more practical option if you need transparency for optical measurements (e.g. qPCR) and protection from unintended piercing.

            Permanent or temporary sealing?


            Another key consideration is whether your seal needs to be permanent or temporary. If you need permanent sealing, heat-sealing foils and films are a durable long-term option, providing strong protection against evaporation. For applications requiring temporary sealing, self-adhesive options and sealing mats are an ideal choice, offering easy, residue-free removal.

            Conducting qPCR?


            Masterclear real-time PCR film is optimized for maximum light transmission. Transmission values of > 90 % between 350 nm and 750 nm guarantee optimal excitation of your fluorescent dyes and optimal readout of the emitted fluorescence.

            Using automated systems?


            Our Heat Sealing Foils are made of aluminum. They provide a strong heat seal that prevents evaporation, even with low sample volumes. They also can be easily pierced by autosamplers, making them particularly well-suited for high-throughput automated assays.
