The stopcocks are defined by their nominal (bore) diameter and large end diameter and length of the ground zone.
BS 1751 on straight-bore glass stopcocks for general purposes is useful for:
Laboratory glassware refers to a variety of equipment used in scientific work and is traditionally made of glass. Glass can be blown, bent, cut, molded, and formed into many sizes and shapes A stopcock is a form of valve used to control the flow of a liquid or gas. The term is not precise and is applied to many different types of valves.
BS 1751 provides you guidance with the ground zone, dimensions, and series of sizes of glass straight-bore stopcocks. BS 1751 guides you with sidearms, materials and construction of the glass straight-bore stopcocks. BS 1751 helps you manufacture high-quality glass straight-bore stopcocks.
