What Are Plate Sealing Mats and Films?

Plate sealing mats and sealing films are commonly used in laboratory settings to securely seal deep well plates and PCR plates. These seals help prevent evaporation, contamination, and cross-contamination during various biological or chemical experiments.
  • Plate Sealing Mats: These are flexible mats made of materials such as silicone or thermoplastic elastomers (TPE). They are designed to fit snugly over the top of a deep well plate or PCR plate, creating an airtight seal. Plate sealing mats often have individual wells that can be pierced with a pipette tip or other instruments for sample access.

  • Sealing Films: Sealing films are typically made of optically clear polyester, polypropylene, or aluminum foil combined with a strong adhesive backing. They are available in pre-cut sheets or roll formats. Sealing films are placed on top of the plate, and pressure is applied to ensure a tight seal. Some sealing films also come with perforations or easy-to-peel tabs for easy removal.

  • Both plate sealing mats and sealing films provide effective barriers against contamination, minimize sample loss due to evaporation, and maintain sample integrity during storage or incubation. They are essential tools in various applications, including PCR, nucleic acid amplification, sample storage, and high-throughput screening.

Are Plate Sealing Mats and Films Compatible with Different Plate Formats?

Yes, plate sealing mats and films are generally compatible with different plate formats. These include microplates, PCR plates, deep-well plates, storage plates, and more.
