Savillex molded PFA vials are widely used in the preparation and storage of a variety of samples for sensitive analyses.  The flat exterior surface and high service temperature range of Savillex PFA vials make them ideal for use directly on a hot plate, and the inert properties of PFA allow for the most rigorous acidic sample preparations without fear of comprising or adulterating the original sample material.  The vial interior is designed to maximize recovery of the sample from inside of the vial. Savillex PFA vials are the best choice for trace level analyses under the most demanding applications.
