Description:

Material - The cover is made of good aluminum and plastic, smooth and burr-free after opening, offering a secure seal for glass vials.
Good Seal - The equipped plastic-aluminum lid ensures the tightest seal and reduces the possibility of sample evaporation. This crimp top vial provides a good seal for long-term sample storage.
How to Use - To open, flip off the plastic cap and remove the aluminum seal using pliers if necessary. The flip off seal can withstand high temperatures. But this cover is fully tear-off, and when you tear off its plastic cover, the aluminum cover becomes unusable.
Application - Our Flip Off Caps can be used in the laboratory and at home, with a good sealing effect and convenient storage. Suitable for oral liquid bottles, original solution bottles, essential oil bottles, freeze-dried bottles, etc.
