  • GLASS, GLASS ARTICLE, METHOD OF MAKING THE GLASS, USE OF THE GLASS AND FLASH LAMP COMPRISING THE GLASS
    Publication number: 20240124345
    Abstract: A glass has a coefficient of thermal expansion in a temperature range from 20° C. to 300° C. of 4.5 ppm/K or less, and a T4 temperature, defined as the temperature at which the glass has a viscosity of 104 dPa*s, at 1500° C. or more, and having a reboil propensity score of less than 10 measured in a reboil propensity test. The reboil propensity score is determined as a number of bubbles per glass rod formed from the glass after the reboil propensity test.

  • METHOD FOR ERADICATING METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS
    Publication number: 20220177352
    Abstract: A glass has a transmission throughout a wavelength range of from 207 nm to 222 nm of at least 60%, measured at a thickness of 1 mm. The glass is a borosilicate glass having a total platinum content of not more than 3.5 ppm, and a hydrolytic resistance characterized by an extracted Na2O equivalent in ?g per g glass determined according to ISO 719 of not more than 250 ?g/g.

  • METHOD FOR ERADICATING PATHOGENS
    Publication number: 20220177354
    Abstract: A glass has a transmittance at a wavelength of 220 nm of at least 30% and a transmittance at a wavelength of 200 nm of less than 4.0%, the glass having a total platinum content of less than 3.5 ppm. A device and a sterilizer include a light source configured to output ultraviolet light and a lamp cover covering the light source and including the glass.
