GE 214A

OH <1.00 PPM
This is identical to the standard 214 but is produced with lower hydroxyl content. “A” products contain <1ppm (OH)- and are intended for metal halide lamps and other applications where the quartz must be devoid of hydroxyl as well as all dissolved gases.

Typical Application
Anti-bacterial and other lamps where UV transmittance in the germicidal range is required, but where deeper UV radiation or ozone generation is undesirable.
