  Neutral Glass tubing

    The optimal choice used for pharmaceutical glass containers must be neutral borosilicate glass tubes due to numerous advantages over other primary packaging materials available on the market. Four Star Glass was far ahead of his time in China when he introduced FS50 tubing in 2007 for pharmaceutical packaging. Since then, FS50 glass tubing has been improved year by year to approach premium quality glass of the first hydrolytic class. This unique product in China has outstanding chemical resistance, neutrality, and its exceptional strength as well as resistance to heat attack. Containers from FS50 glass tubes are geared to storing and delivering a wide range of injectable, as well as sensitive biotech drugs.Today, Four-star is still a leading company in the Chinese market for top-of-the-range pharmaceutical packaging glass tubing.

    In case the specification of tubes required by a customer is unconventional, it is necessary to provide a drawing to check, if available we also acc PH。Eur。, or USP to supply。
