When SCHOTT Glass, the "quality" in the global specialty glass field, meets Sumspring, the "innovative force" of domestic testing instruments, a cooperation centered on "quality" is injecting new momentum into the global glass industry. Recently, after multiple rounds of rigorous technical evaluation and performance verification, Schott Glass has finally selected the Sanquan Zhongshi Glass Bottle Testing Instrument to "enhance" the quality control of its core products such as medicinal glass and food packaging glass.
Schott Glass is a partner of many pharmaceutical companies worldwide for its high-quality neutral borosilicate glass tubes and bottles. Its products are widely used in fields that require packaging, such as vaccines, biologics, and anti-cancer drugs. To ensure that every glass bottle can maintain mechanical strength, chemical stability, and sealing integrity, Schott has put forward almost stringent requirements for quality monitoring during the production process.
Previously, SCHOTT Glass had been using foreign testing instruments. Sanquan Zhongshi's instruments have won SCHOTT's recognition for their advantages in accuracy, stability, repeatability, and data traceability.

Sanquan Zhongshi assists SCHOTT Glass in controlling the quality of glass bottles with strict standards
As a pioneer in the field of packaging material testing in China, Sanquan Zhongshi has been deeply involved in the research and innovation of packaging material testing technology for many years. Its products not only comply with domestic and international standards such as the Chinese Pharmacopoeia, USP (United States Pharmacopeia), EP (European Pharmacopoeia), but also demonstrate unique advantages in hardware design, software algorithms, and user-friendly operation.
The success of this cooperation is another powerful proof of Sumspring Zhongshi's technological strength, and it has also prompted Sumspring Zhongshi to continuously innovate its technology. We hope to provide a more solid guarantee for the stability and effectiveness of drugs from the source through the strong combination of upstream packaging materials and testing technology, and jointly promote the continuous improvement of global pharmaceutical packaging quality control level, contributing technological strength to safeguarding human health!
