Aluminum heat-sealing film is a type of laboratory consumable used to seal microplates, including PCR plates, deep-well plates, and microtiter plates. Unlike clear heat-sealing film, aluminum heat-sealing film is opaque and typically made of aluminum foil with a heat-activated adhesive layer on one side.

Here are some key features and characteristics of aluminum heat-sealing film:

  • Heat-Sealing Capability: Aluminum heat-sealing film is designed to be heat-sealed onto the microplate using a heat-sealing instrument or thermal cycler equipped with a heat-sealing module. When heated, the adhesive layer melts and bonds the film to the microplate, forming a secure seal over the wells.
  • Opaque Barrier: The aluminum foil construction provides an opaque barrier that blocks light, preventing photodegradation of light-sensitive samples and reagents stored in the microplate wells.
  • Chemical Resistance: Aluminum foil is resistant to many chemicals commonly used in molecular biology and biochemistry applications, providing protection against solvent evaporation and contamination.
  • Puncture Resistance: It provides excellent puncture resistance, protecting samples from physical damage and leakage during handling, storage, and transportation.
  • Heat Transfer Efficiency: Aluminium foil has high thermal conductivity, which ensures efficient heat transfer during thermal cycling in PCR or other temperature-sensitive applications.
  • Peel able or Permanent: Aluminium heat-sealing film may come in peel able or permanent versions. Peelable films can be easily removed from the microplate without leaving residue, while permanent films provide a more secure seal that requires cutting for removal.
  • Sterile Options: Some aluminum heat-sealing films come pre-sterilized, ensuring that sealed microplates remain free from microbial contamination.
  • Customizable: Aluminum heat-sealing film can be easily trimmed to fit specific microplate formats, allowing for customization based on experimental needs.

Aluminum heat-sealing film is commonly used in molecular biology laboratories for sealing microplates in applications such as PCR, enzyme assays, ELISA, and sample storage. When selecting aluminum heat-sealing film, it’s important to consider factors such as compatibility with microplate types, heat-sealing temperature requirements, opacity, chemical resistance, and sterility.
