Introduction of medicinal rubber plug puncture performance testing instrument
The medicinal rubber stopper, specifically the butyl rubber plug, is widely recognized for its outstanding sealing properties and strong resistance to chemical corrosion. It is currently the only type of rubber plug that comes into direct contact with glass vials in the pharmaceutical packaging industry, as well as with large-volume infusion soft bags. Due to its extensive application and growing popularity, the use of medicinal rubber stoppers has become increasingly widespread.
Since the 2002 edition of the *Compilation of Standards for Packaging Materials and Containers in Direct Contact with Drugs*, the State Food and Drug Administration (SFDA) has mandated puncture performance testing for medicinal rubber stoppers. This includes critical parameters such as puncture force and the number of chips generated during the puncturing process. These tests ensure the reliability and safety of the stoppers in pharmaceutical applications.
Labthink, a leading provider of inspection instruments and services, has been offering high-quality quality control solutions to the global pharmaceutical industry for many years. The Labthink XLW series features four intelligent electronic tensile testing machines—XLW, XLW (PC), XLW (M), and XLW (B)—each equipped with a specialized puncture performance test fixture designed for medicinal rubber stoppers. These devices are tailored to meet the specific needs of rubber plug manufacturers and pharmaceutical companies, providing accurate and reliable results.
Beyond puncture testing, the equipment also supports additional functions such as measuring tensile strength, elongation, heat-seal strength (for materials like medicinal aluminum foil, composite films, and PVC hard sheets), tear resistance, and peel strength. This multi-functional design significantly enhances the efficiency and cost-effectiveness of laboratory operations in pharmaceutical production facilities.
In addition, Labthink offers a specialized device for evaluating the sealing performance of puncture sites. This tool is particularly useful for pharmaceutical and rubber plug manufacturers who need to conduct post-puncture sealing tests. By integrating these capabilities, Labthink ensures comprehensive support for quality assurance in drug packaging.
In addition to puncture performance testing, Labthink provides a wide range of testing solutions for pharmaceutical packaging materials. These include oxygen transmission rate testing using the PERME OX2/230 system, water vapor transmission testing via the PERME W3/330 system, and leakage and seal strength testing with the LSSD-01 device. With these advanced tools, Labthink continues to support the evolving needs of the pharmaceutical industry.
Labthink is committed to fostering broader collaboration with pharmaceutical enterprises and research institutions. For more information or to discuss your specific testing requirements, feel free to contact Guo Sijia at gz@labthink.com.
