Safety Coated Glass Boston Round Bottles are glass Boston Rounds that have been coated in a layer of Plastisol, a solution of PVC resin in a liquid plasticizer that cools to form a perfectly-fitting plastic coating. These plastic-coated glass Boston Round bottles are easier to grip and harder to break than ordinary glass bottles, yet still offer the chemical resistance and minimal interference of glass. In the case that the glass does break, the plastisol coating will contains the contents in the bottle long enough to allow for proper disposal.
Boston Round bottles feature a round body, curved shoulders, and a narrow screw neck opening. Safety plastic-coated Boston Round bottles are ideal lab bottles for handling volatile substances.
