Steel Laboratory Safety Cans have all the benefits of the Type I cans, plus added features to make these the choice of lab professionals for safe dispensing of hazardous liquids into test tubes, small flasks and beakers. Fill spouts have self-close pressure relief caps and double-mesh flame arresters. Self-closing faucets provide trouble-free dispensing. Cans fitted with smaller faucet (Model 6201028) offer easier dispensing in lab environments, while faucet (Model 6201032)is better suited for heavy, industrial use.
