Overview

EN ISO 4796-2:2000 - Laboratory glassware - Bottles - Part 2: Conical neck bottles (ISO 4796-2:2000) defines a standardized series of conical neck laboratory bottles for the storage of liquid and solid chemicals and reagents. Published by CEN and identical to ISO 4796-2:2000, the standard covers bottle types, nominal capacities, materials, construction features, socket/ground-joint compatibility and marking. It ensures interchangeability, safety and predictable performance for laboratory glassware used in research, quality control and production labs.

Key topics and technical requirements

• Types and identification
  • Four bottle types: WS (wide-neck socket), WJ (wide-neck with ground joint), NS (narrow-neck socket), NJ (narrow-neck with ground joint).
  • Designation format example: Laboratory bottle ISO 4796-2 - 100 WS.
• Nominal capacities
  • Wide-neck series: 50, 100, 250, 500, 1 000, 2 000 ml.
  • Narrow-neck series: 25, 30, 50, 100, 250, 500, 1 000, 2 000, 2 500, 5 000, 10 000, 20 000 ml.
  • Nominal capacity is measured to the turn of the shoulder; total capacity to the base of the neck is ≈ 15% greater.
• Material and glass quality
  • Bottles shall be made of clear, colourless or amber borosilicate glass 3.3 (ISO 3585) or other glass meeting class HGB 3 (ISO 719) for hydrolytic resistance.
  • Internal stress and visible defects are to be minimized to reduce fracture risk from thermal/mechanical shock.
• Dimensions and tolerances
  • Dimensional data (heights, diameters, wall thickness minima, and socket/joint sizes) are specified in the standard’s Table 1 and figures. Interchangeable ground joints must comply with ISO 383.
• Construction features
  • Stable bases, smooth shoulder-to-neck transitions, tapered sides, and a strengthening lip to facilitate pouring.
  • Optional protective plastic coatings are permitted if resistant to steam sterilization at 135 °C.
• Stoppers
  • Acceptable stoppers: glass (matched expansion, ground to ISO 383), rubber (for smooth sockets), or inert plastics (e.g., polypropylene) sized for joints.

Applications and users

• Practical uses: chemical storage, reagent containment, sterile or steam-sterilizable containers, general laboratory ware in academic, pharmaceutical, industrial and analytical labs.
• Primary users: glassware manufacturers, laboratory procurement teams, quality assurance personnel, lab managers, equipment designers and regulatory/standards committees who require consistent dimensions and material properties for safe handling and interchangeability.

Related standards

• ISO 383 - Interchangeable conical ground joints
• ISO 3585 - Borosilicate glass 3.3 - Properties
• ISO 719 - Hydrolytic resistance of glass
• ISO 4796-1:2000 - Bottles - Part 1: Screw-neck bottles

This standard provides clear specifications for reliable, interoperable conical neck bottles - essential for safe chemical storage and consistent laboratory operations.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 4796 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 4796-2 was prepared by Technical Committee ISO/TC 48, Laboratory glassware and
related apparatus, Subcommittee SC 2, General laboratory glassware (other than measuring apparatus).
