Product Category Description:

Vials feature a beveled crimp finish which gives a much tighter seal than flat crimp surfaces. Manufactured from clear 33 expansion borosilicate glass. Flat-bottom vials feature a slightly longer neck, providing a custom fit for Carlo Erba and Agilent* autosamplers. Round-bottom vials are designed to fit PerkinElmer*, Tekmar*, and Varian* headspace autosamplers. Seals have attached septa, unless otherwise specified.
