Overview
EN ISO 4796-3:2000 is an international standard published by CEN that specifies requirements for laboratory glassware aspirator bottles. This part of the ISO 4796 series focuses on aspirator bottles with either a screw neck or a conical neck, designed for the safe and effective delivery of liquid chemicals and reagents in general laboratory applications. The standard ensures uniformity in design, dimensions, and materials, facilitating interoperability and safety in laboratory environments.
The aspirator bottles defined in ISO 4796-3:2000 serve as essential components in laboratories, providing reliable containment and controlled liquid dispensing solutions. This facilitates accurate reagent handling, contributing to quality laboratory operations and experimental success.
Key Topics
- Scope and Application: Defines aspirator bottles suitable for laboratory liquids, available in screw neck or conical neck designs.
- Types and Capacities: Includes three bottle types:
- ASN: Aspirator bottles with a screw neck
- ACS: Aspirator bottles with a conical neck socket
- ACJ: Aspirator bottles with an interchangeable conical ground joint
Nominal capacities range from 0.5 L to 20 L for diverse laboratory volume requirements.
- Design Specifications:
- Dimensions and tolerances for height, diameter, neck, and wall thickness are standardized to ensure compatibility and safety.
- Bottles must have a stable base, smooth transitions between sections, and a stout neck with a strengthening lip for spill prevention.
- Wall thickness minimums prevent fragility and breakage.
- Material & Construction: Glass quality must allow for even distribution and resistance to laboratory conditions. Optional protective plastic coatings enhance durability and safety.
- Outlets and Closures: Bottles have sidewall outlets approximately 28 mm from the base, equipped with standardized threaded or ground joints for secure connections with stoppers or apparatus. Closures comply with complementary parts of ISO 4796 for screw neck and conical neck bottle types.
- Marking and Designation: Clear labeling rules facilitate identification by type and nominal capacity, supporting traceability and proper usage in lab workflows.
Applications
Aspirator bottles adhering to EN ISO 4796-3:2000 are critical in:
- Chemical and biochemical laboratories requiring controlled dispensing of reagents and solvents.
- Analytical and research facilities that depend on standardized, high-quality glassware to maintain consistency in experiments.
- Industrial laboratories performing liquid handling with corrosive or sensitive chemicals where leak-proof and durable containers are essential.
- Educational labs aiming to align with international safety and quality standards for laboratory equipment.
The standard’s comprehensive coverage of bottle types, sizes, neck designs, and connections supports diverse liquid handling needs, while ensuring safety, accuracy, and compatibility in laboratory glassware applications.
