James Alexander’s snap top vial is made of USP type I borosilicate glass. Borosilicate glass is composed principally of silicon dioxide and boric oxide, with low levels of the non-network forming oxides. It is a chemically resistant glass characterized by low leachability.
All sizes of snap top vials can be silk-screened (printed) in a variety of colors. The printing may include a lot number, product code number, your company logo, and descriptive information regarding the product.
To address concerns regarding broken glass when the snap top vial is opened, plastic “safety-break sleeves” are available to protect the user.
