Abstract
An ultraviolet ray transmitting glass composition including the following components, in terms of mass % or mass ppm: 60 to 79% SiO; 0 to 1% BO; exceeded 0% but not more than 20% AlO; 0 to 10% LiO; 5 to 20% NaO; 0 to 15% KO; 0 to 10% MgO; 0 to 10% CaO; 0 to 15% SrO; 0 to 2% refining agent; 2 to 20 ppm T-FeO(in which T-FeOdenotes a total iron oxide content obtained by converting all of iron compounds into FeO); and 0 to 200 ppm TiO. The ultraviolet ray transmitting glass composition is suitable for a glass article, such as a bioanalytical device that is used for analysis using ultraviolet rays.
