27 Mar.,2025

The 3-point flexure test is a crucial method for testing the break points and break forces of snapoff ampoules. This test is essential in ensuring the safety and reliability of ampoules, especially when they are used in pharmaceutical applications.

 

The 3-point flexure test is a crucial method for testing the break points and break forces of snapoff ampoules. This test is essential in ensuring the safety and reliability of ampoules, especially when they are used in pharmaceutical applications. In this article, we'll explore how the universal 3-point flexure test kit works, the types of ampoules it can accommodate, and how it helps determine breakage characteristics.

What is the 3-Point Flexure Test?

The 3-point flexure test is a standardized procedure used to measure the break point and the force required to break an ampoule. This test is widely used in quality control processes to ensure that the ampoules meet industry standards for strength and durability. The test evaluates the structural integrity of glass ampoules by applying force at three points, typically at the midpoint and two support points, until breakage occurs.

Why Use the 3-Point Flexure Test Kit?

The universal 3-point flexure test kit is specifically designed to measure the breakage forces of various ampoules. It can accommodate ampoules ranging from 1-2 ml up to 20-30 ml in capacity. The key advantage of this kit is its adjustability. The kit includes shims and a movable anvil, making it versatile enough to test different ampoule geometries.

Additionally, the test kit is built to handle a nominal force of 500 N, providing accurate results for a wide range of testing conditions. A protective pane is highly recommended during the test to prevent glass breakage from posing a risk.

Key Features of the 3-Point Flexure Test Kit

  1. Adjustable for Various Ampoule Sizes: The kit can be adjusted for ampoules ranging from 1 ml to 30 ml. It includes flexible components like shims and a movable anvil to fit different ampoule shapes and sizes.
  2. Durable and Reliable Design: The kit is designed to withstand the pressures of the testing process. Its robust construction ensures reliable and repeatable results for accurate testing.
  3. Precision Measurement: The flexure table and adjustable prism-shaped anvils provide precise measurements of break points and forces, ensuring that each test is consistent and accurate.

How the Test is Performed

The test is simple yet effective. Here's an overview of the process:

  1. Preparation: Place the ampoule on the flexure table. Adjust the anvils and shims to ensure the ampoule is properly positioned.
  2. Testing: Apply force gradually until the ampoule breaks. The break point and the force required to break the ampoule are recorded.
  3. Results: The results indicate the point at which the ampoule breaks and the force needed to cause breakage. These results can be used to assess the ampoule's strength and ensure it meets required standards.

Applications of the 3-Point Flexure Test Kit

This test kit is widely used in the pharmaceutical industry, where the integrity of glass ampoules is crucial for packaging medicines. The break points and break forces measured during testing help determine the quality of ampoules, ensuring they are strong enough to withstand handling during production and transport without breaking prematurely.

Conclusion

The 3-point flexure test kit is an essential tool for testing the break points and break forces of snapoff ampoules. Its adjustable design allows for testing a wide range of ampoule sizes, ensuring the strength and durability of the product. Whether for pharmaceutical or other applications, this kit provides reliable and repeatable results, making it an invaluable tool in quality control processes.
