The breaking strength of glass products is strongly influenced by internal mechanical stresses. This is particularly important when the products are exposed to mechanical loads or strong temperature fluctuations. In the case of pharmaceutical primary packaging made of glass such as vials, syringes and ampoules, the constant testing and monitoring of residual stresses is therefore an important part of quality control – during production at the glass supplier, but also as an incoming inspection in the pharmaceutical industry.

The StrainScope Pharma Tester, specially developed for this measurement task, delivers objective and precise measurement results. An automatic device rotates the test specimen and thus reliably and reproducibly identifies the maximum value of the residual stress – in just a few seconds.

The convenient archive function ensures that all measurement results are fully documented.

The fracture strength of glass is strongly determined by internal mechanical stresses. An inhomogeneous glass composition leads to so-called cord stresses, which remain undetected with conventional polariscopes or polarimeters. The manual measurement by means of a polarizing microscope is very time-consuming and requires specially trained and experienced operating personnel.

The StrainScope Cord Tester automates the stress measurement in ring sections of container glass and shows the distribution of compressive and tensile stresses in real time – directly in the desired measuring unit.

This allows you to perform the quality inspection close to production and with little training. You can respond quickly to production problems and avoid production losses and expensive complaints.

Even in modern glass factories, residual stresses after the cooling process are still visually monitored with simple strain testers. The results are inaccurate, vary from user to user and are often under-documented.

The StrainScope Annealing Tester delivers objective and accurate measurement results in a minimum of time – in all standard measuring units and compatible with established rating systems, such as apparent and real temper number according to ASTM C148. This allows you to specifically optimize production processes. Not only consistently high product quality is achieved, you can also minimize the energy consumption in the cooling process for each item.

The convenient archive function ensures that all measurement results are completely documented. In case of a later complaint the proof of quality is provided quickly and beyond doubt.
