Laboratory Glassware - Bottles - Part 2: Conical Neck Bottles

This technical specification outlines the dimensional requirements and general principles for the design of laboratory glassware, specifically focusing on stoppered flasks with conical joint sockets. The document establishes precise tolerances and specifications to ensure interchangeability and compatibility between vessels and their corresponding stoppers from different manufacturers. It defines the geometric characteristics of the conical joints, including the standard taper and associated dimensions necessary for creating gas-tight and liquid-tight seals during laboratory procedures. Adherence to these guidelines facilitates the seamless integration of equipment within scientific workflows, minimizing the risk of leakage or mechanical failure during experiments involving volatile substances or reactions requiring controlled atmospheres. The standard addresses the manufacturing consistency required for these essential tools, ensuring that the glass surfaces maintain integrity under typical laboratory conditions. By providing a unified framework for the production of these items, it supports quality assurance practices within the global scientific community, allowing researchers and technicians to rely on consistent performance across various instruments used for storage, mixing, and reaction containment.
