Traditional borosilicate glass vials
Traditional vials are generally borosilicate glass or soda-lime glass control (molded) injections and are available in brown, transparent, and other types. The bottleneck is smaller, the bottleneck is thicker than the bottleneck, and it is slightly smaller than the bottle. It is generally used as a packaging for vaccines, biological agents, powder injections, and freeze-dried drugs.
Borosilicate Glass Category:
1.Low-alkali borosilicate glass: refers to the SiO2-B2O3-R2O composition, contains glass with low R2O and high SiO2, has small linear expansion coefficient, small dispersion, good chemical stability, high thermal stability, and good electrical insulation. Previous glass (such as Pyrex), heat-resistant bedding, ampule glass, neutral glass, electro vacuum glass, optical glass, LCD substrate, solar panel and collector.
2.Middle borosilicate glass: Refers to the SiO2-B2O3-RO component, such as SiO2-B2O3-PbO component, using the preparation of optical glass, low temperature glaze; SiO2-B2O3-PbO/ZnO component for crystalline powder solder, as cathode ray Used for the sealing of tubes (CRT); SiO2-B2O3-ZnO for passivation of rectifiers and electronic devices.
3. High borosilicate glass: refers to SiO2-B2O3-La2O3-RmOn components, such as SiO2-B2O3-La2O3-CaO-ZnO-ZrO2 components with high refractive index, low dispersion, good chemical temperature, low devitrification, Used as optical glass.
4.Rare-earth-doped borosilicate glass: Based on SiO2-B2O3-RmOn, laser glass doped with Pr and Nd, nonlinear optical glass doped with Au, Ag, and Cu, doped CdS, ZnS:Mn nanocrystals Luminous glass.
