    Six sizes with bores from 1mm to 10 mm.

    Scope - (Show below) - (Hide below)

    This International Standard specifies requirements and dimensions for two series of glass straight-bore stopcocks for general-purpose use. The stopcocks are defined by their nominal (bore) diameter and large end diameter and length of the ground zone. It is recommended that, in national standards, only one of the series should be specified.

    NOTE Annex A lists additional International Standards for other general-purpose laboratory glassware.
