ABSTRACT:
In a method for reducing the latent low-level phosphorescence of laboratory glassware, the glassware is illuminated by infrared light with a wavelength of about 780 nanometers. A suitable infrared light source can be a xenon flash apparatus fitted with an infrared light filter. A single flash from the xenon apparatus can substantially reduce the latent low-level phosphorescence of laboratory glassware to a baseline phosphorescence level.
