Overview

EN ISO 4796-2:2000 specifies requirements for laboratory glassware, focusing on bottles with conical necks. Developed by CEN and aligned with ISO 4796-2:2000, this standard establishes a series of glass bottles with wide or narrow conical necks-available with or without ground joints-suitable for the safe storage of liquid and solid chemicals and reagents. The standard covers multiple capacities and design variants to ensure compatibility with general laboratory processes and international best practices for laboratory safety and chemical containment.

Key Topics

• Bottles with Conical Necks: The standard defines four main types of laboratory bottles:
  • Wide-necked bottles with a conical socket (WS)
  • Wide-necked bottles with interchangeable conical ground joints (WJ)
  • Narrow-necked bottles with a conical socket (NS)
  • Narrow-necked bottles with interchangeable conical ground joints (NJ)
• Capacities: Wide-necked bottles are available in sizes from 50 ml to 2,000 ml. Narrow-necked options cover an expanded range from 25 ml to 20,000 ml.
• Material Requirements: Bottles must be constructed from clear, colorless, or amber borosilicate glass as per ISO 3585, or other glass types complying with ISO 719 standards for hydrolytic resistance.
• Design Features:
  • Reinforced lip for safe pouring
  • Smooth and robust neck for compatibility with stoppers
  • Stable base to prevent accidental tipping
  • Even distribution of glass to resist thermal and mechanical shock
  • Option for external plastic coating for added protection
• Stoppers: Bottles are provided with glass, rubber, or inert plastic stoppers, matched to bottle material and neck specification for leak-free sealing.

Applications

• Chemical Storage: Ensures reliable, safe containment for both liquid and solid laboratory chemicals, reducing risk of contamination and spillage.
• General Laboratory Use: Standardized dimensions and neck types facilitate compatibility with laboratory apparatus, stoppers, and automation equipment.
• Reagent Preparation: Conical neck bottles allow easy access and pouring, supporting precise measurement and transfer of reagents.
• Sample Storage: Durable construction and chemical-resistant materials make these bottles suitable for both short-term and long-term sample retention.

The implementation of EN ISO 4796-2:2000 supports laboratory quality management by ensuring uniformity in glassware, minimizing operational errors, and promoting user safety. Laboratories benefit from standardized bottles with known performance characteristics, facilitating international procurement and compliance with laboratory protocols.

Related Standards

• ISO 4796-1:2000: Laboratory glassware - Bottles - Part 1: Screw-neck bottles; provides requirements for a different type of laboratory bottle suited for other applications.
• ISO 383: Laboratory glassware - Interchangeable conical ground joints; referenced for ground joint dimensions and conformity.
• ISO 3585: Borosilicate glass 3.3 - Properties; sets out the glass material properties required for chemical and thermal resistance.
• ISO 719: Glass - Hydrolytic resistance of glass grains at 98 °C - Method of test and classification; referenced for measuring glass resistance to water attack.

EN ISO 4796-2:2000 delivers essential guidance for laboratories in need of dependable, safe, and standardized glass conical neck bottles, playing a critical role in the effective management and storage of chemical substances worldwide. By following this standard, organizations ensure consistency and quality across 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).
