Ampoule Three Point Bending Tester – ISO 9187

Introduction to Ampoule Break Strength Testing

Pharmaceutical ampoules are widely used for sterile drug delivery, requiring precise design and quality assurance to ensure safe, effective, and compliant usage. The ampoule three point bending tester plays a vital role in this process by evaluating the mechanical strength of the ampoule neck, ensuring that the force required to open it is within a predictable and safe range.

This instrument provides quantitative, repeatable data, helping pharmaceutical manufacturers meet the rigorous demands of ISO 9187, enhance product reliability, and protect both users and patients. As a leading solution provider, Cell Instruments Co., Ltd. offers advanced bending testers that align with industry needs.

Test Ampoule Strength According to ISO 9187

The ampoule three point bending tester is primarily designed to test ampoule breaking strength according to ISO 9187, the internationally recognized standard specifying mechanical tests for ampoules. ISO 9187 ensures that ampoules possess sufficient strength to resist accidental breakage during transportation and handling, while also being easy to open when required.

ISO 9187 specifically addresses:

  • Ampoule form and dimensions

  • Breaking force requirements

  • Fracture zone design

  • Test methods and conditions

Using ISO-compliant testing not only guarantees regulatory compliance, but also improves batch consistency and end-user safety, essential factors in modern pharmaceutical packaging.

Working Principle of the Ampoule Three Point Bending Tester

The ampoule three point bending tester works by placing an ampoule horizontally on two support points, with a third point (the plunger) applying vertical force at the ampoule’s neck. This setup simulates the mechanical stress experienced during manual breaking. The tester records the peak force at which the neck fractures.

Key steps include:

  • Fixture Installation: Choose a suitable metal support according to ampoule size (commonly 1 to 30 mL).
  • Sample Placement: Secure the ampoule on the supports.
  • Speed Adjustment: Set the test speed (e.g., 10 mm/min as standard, adjustable from 1–500 mm/min).
  • Fracture Initiation: The plunger descends until the ampoule neck breaks.
  • Data Capture: A high-precision load cell records maximum, minimum, and average breaking force.

This method allows manufacturers to monitor product quality, adjust materials or processes, and train users to safely handle ampoules in clinical settings.
