Crimp vials are excellent sample containers for automatic dispensers of gas and liquid chromatographs and for storing samples or calibration solutions. The technique of closing them is very important for proper tightness. Due to leakage caused by improper sealing, solvent evaporation or loss of analytes may occur.
A correctly closed vial can be recognized by the fact that its cap rotates with difficulty after closing and the septum is straight.
A vial that is closed with too much force can be recognized by the fact that its cap cannot usually be turned at all and, in addition, it has a bent septum (inwards). If the septum is punctured by the needle of the microsyringe, the septum will be heavily stressed and thus the vial's tightness will be compromised.
A vial that does not have a properly closed cap due to the low power of the crimping pliers is manifested by easy rotation of the cap and, in some cases, unfastened aluminum material around the lower edge of the vial neck.
You can set the correct force of the closing pliers.
In older types of pliers, the force is adjusted by turning the Allen key inside the jaws. Pliers also have a stop screw, which is used to set the safety distance, in order not to use too much force and thus to avoid leakage or even mechanical damage to the vial.
