Excellent chemical durability for use in pharmaceutical containers such as ampoules, vials, drug prefilled syringes, and chemical labware such as test tubes.
BS-A is designed to protect sensitive pharmaceutical preparations such as vitamins from the blue light and UV range. It complies with the Japanese Pharmacopoeia, which specifies visibility not only in the blue and ultraviolet light range, but also in the visible light range.
principle
The purpose is to eliminate permanent stress and structural imbalance in glass products. Glass is a poor heat conductor. After the product is formed, a temperature difference occurs between the surface layer and the inner layer during the cooling process. When the surface layer is solidified and the inner layer is viscous, the temperature difference exists but the stress relaxation does not exist. This temperature difference is when the surface layer is cooled to room temperature. , the inner layer continues to cool down and shrink, and is hindered by the surface layer to generate tensile stress, and at the same time, the surface layer generates compressive stress, which exists permanently
