We produce best quality pharma neutral boron glass tubes of different specifications. They’re used to make neutral boron ampoules.
Neutral borosilicate pharma glass is a kind of pharma glass, which is mainly used for medicine or drug packaging. It has the advantages of small expansion coefficient, strong resistance to extreme cold and heat, high mechanical strength, strong impact resistance, good chemical stability, acid, alkali and water resistance.

Our factory has the advanced automatic detection system
Full vision imaging automatic inspection can accurately and reliably separate genuine products from unqualified products.
Promote the transformation from manual sampling inspection to mechanized full inspection. More effectively avoid specification deviation, cracks and visible foreign matters (glass chips, black spots, yellow spots, white spots, etc.).

The visual imaging principle is adopted for detection, which can judge the visible foreign matter more accurately, accurately and reliably realize the separation of genuine and unqualified products, and minimize the missed detection rate.
High standards and strict requirements shall be maintained in the detection process, and the computer shall monitor the operation status in real time and control the product quality.
Intelligent sorting technology and classified statistics of detected data provide data reference for process improvement.
