Snap ring / crimp neck vials N 11 may be sealed either with a snap ring closure N 11 or a crimp closure N 11. In combination with either hard or soft snap ring closures, snap ring vials offer a quick, convenient sealing method which, however, should only be used in HPLC. Snap ring vials are compatible with almost all autosamplers, even with those with robotic handling. With a closure of your choice snap ring vials N 11 may also be supplied as a Vial Kit.
