Overview
ISO 4796-2:2000 is an international standard developed by the International Organization for Standardization (ISO) specifying requirements for laboratory glassware, specifically conical neck bottles used for general laboratory storage. This standard covers bottles with conical necks-both wide and narrow-with or without ground joints, designed to safely store liquid and solid chemicals and reagents in laboratories.
Part 2 of the ISO 4796 series focuses exclusively on conical neck bottles, complementing Part 1 on screw-neck bottles and Part 3 on aspirator bottles. The standard ensures safety, consistency, and compatibility of laboratory bottles globally, supporting uniform laboratory practices.
Key Topics
Types of Conical Neck Bottles
ISO 4796-2 defines four types:- WS: Wide-neck bottles with a conical socket
- WJ: Wide-neck bottles with interchangeable conical ground joint
- NS: Narrow-neck bottles with a conical socket
- NJ: Narrow-neck bottles with interchangeable conical ground joint
Capacities and Dimensions
Bottles are standardized in nominal capacities ranging from 25 ml up to 20,000 ml for narrow neck types and 50 ml to 2,000 ml for wide neck types. Dimensions including total height, outside diameter, and wall thickness are clearly specified to ensure interchangeability and proper fit with stoppers and other laboratory equipment.Material Specifications
Bottles must be made from high-quality borosilicate glass 3.3 according to ISO 3585 or equivalent glass types meeting ISO 719 class HGB 3 or better, ensuring chemical resistance, thermal shock resistance, and mechanical robustness.Design and Construction Requirements
The bottle design includes a sturdy base for stability, smooth transitions between base, shoulder, and neck, and a stout neck with a lip to facilitate pouring. Optional protective plastic coatings can be applied to help contain glass fragments if broken and withstand steam sterilization.Stopper Compatibility
Glass, rubber, or inert plastic stoppers must be compatible with the conical neck design. Glass stoppers must match thermal expansion properties and conform to the interchangeable conical ground joints per ISO 383.Marking and Designation
Bottles are designated by standard reference (ISO 4796-2), nominal capacity, and type. Example: "Laboratory bottle ISO 4796-2 - 100 WS" indicates a 100 ml wide-neck bottle with a conical socket.
Applications
ISO 4796-2 conical neck bottles are essential in laboratory environments for the safe and reliable storage of chemicals and reagents. Their applications include:
- Chemical Storage – Suitable for storing acids, bases, solvents, and reagents with chemical resistance and inert glass material.
- Sample Preservation – Suitable for preserving liquid or solid samples requiring chemical inertness and controlled sealing.
- Analytical Laboratories – Used for preparation and storage of calibration standards and reagents with standardized neck sizes facilitating equipment compatibility.
- Pharmaceutical and Research – Assures consistent material quality for sensitive applications requiring sterilization and contamination control.
- Quality Control Processes – Enables traceability with standard markings and compatibility with laboratory handling apparatus.
Related Standards
ISO 4796-2 complements related ISO standards for laboratory glassware and chemical storage:
- ISO 4796-1:2000 – Laboratory glassware - Bottles: Screw-neck bottles
- ISO 4796-3:2000 – Laboratory glassware - Bottles: Aspirator bottles
- ISO 383:1976 – Laboratory glassware: Interchangeable conical ground joints used in bottle necks
- ISO 3585:1998 – Borosilicate glass 3.3: Properties and classification
- ISO 719:1985 – Glass: Hydrolytic resistance testing for chemical durability
Adhering to these interconnected standards ensures comprehensive quality, safety, and interoperability of laboratory glassware.
By following ISO 4796-2:2000, laboratories worldwide maintain high standards in glass bottle manufacturing and usage, enhancing chemical safety, reproducibility, and operational consistency in scientific and industrial environments.

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).
Parts 1 and 2 of ISO 4796 cancel and replace ISO 4796:1977 by incorporating the following changes:
a) bottles with capacities of 25 ml, 30 ml, 2 500 ml and 20 000 ml have been added;
b) the material has been more precisely defined;
c) the International Standard has been divided into three parts.
ISO 4796 consists of the following parts, under the general title Laboratory glassware — Bottles:
� Part 1: Screw-neck bottles

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée aux
comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du comité
technique créé à cet effet. Les organisations internationales, gouvernementales et non gouvernementales, en
liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec la Commission
électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI, Partie 3.
Les projets de Normes internationales adoptés par les comités techniques sont soumis aux comités membres pour
vote. Leur publication comme Normes internationales requiert l'approbation de 75 % au moins des comités
membres votants.
