121℃ Glass Grains Hydrolytic Resistance Testing
In the USP <660>, Ph. Eur. 3.2.1, and ISO 720 international pharmacopoeia frameworks, the 121℃ Glass Grains Hydrolytic Resistance Test (Glass Grains Test) is a core parameter for evaluating the chemical resistance of pharmaceutical packaging materials, including injection vials, ampoules, and borosilicate glass. However, traditional manual crushing and sample preparation methods often generate excessive fine dust and significant particle size deviation, directly compromising test reproducibility and data reliability.
