The aluminum foil sealing film for test tubes adopts a multi-layer composite structure, which has excellent sealing and protective properties. Its 12 μ m high-purity aluminum foil layer, combined with medical grade pressure-sensitive adhesive, can effectively block oxygen, water vapor, and microorganisms, preventing sample evaporation and cross contamination. 

The product is compatible with a diameter range of 5-30mm and can withstand temperatures from -80 ℃ to 121 ℃, meeting various experimental needs such as PCR tube sealing, clinical sample preservation, and biological agent storage. The specially designed anti UV and anti freeze properties, as well as optional pre sterilized packaging and a writable surface, make it an ideal choice for laboratory sample management. Easy to operate, sealing can be completed in 3 seconds, providing efficient and reliable sealing solutions for scientific research work. 

The test tube aluminum foil sealing film offers a variety of options, including standard pressure-sensitive, composite aluminum foil, and special enhanced types. Users can choose according to their different needs such as routine experiments, long-term storage, or sterile operations. Its precise design and professional performance ensure the accuracy of experimental data and sample safety, making it an essential consumable for modern laboratories.
