Bottle Caps Selection Of Sample Vial

There are three types of sample vial caps: the jaw cover, the clamping cap, and the screw cap. Each sealing method has its own advantages.

Jaw Cap
The clamp cover presses the gasket between the bottle edge of the glass sample bottle and the folded aluminum cover. The sealing effect is very good, which can effectively prevent the evaporation of the sample. For a small number of samples, manual capping is the best choice.

Bayonet Cap
The clamping cover is an extension of the sealing mode of the jaw cover. The tension of the plastic cover is caused by its attempt to restore its original size. This tension forms a seal between the glass, the bottle cap, and the gasket. The plastic clamping cover can be covered without any tools.
