Description
Neutral Pharmaceutical Glass Tube with Great Hydrolytic Resistance Performance
Pharmaceutical glass tube plays a major role in the manufacturing process of pharmaceutical parental containers.
Neutral Pharmaceutical Glass Tube commonly refers to tubes made from neutral borosilicate glass with a coefficient of mean linear thermal expansion of 5.0. Generally, it has exceptional chemical stability and high heat resistance to thermal shock and sudden temperature change. It is typically used as a raw material by the pharmaceutical packaging companies to manufacture primary packaging products and plays a major role in the manufacturing process of pharmaceutical parental containers.
- Both clear and amber glass tubes are available
- High chemical resistance
- Great hydrolytic resistance
- Compliance with ISO 719 standards
- Customized glass tubes are available
- Special discount for large orders and various promotion campaigns
