Fused quartz lamp tubing is available in the following grades:
214
- Specially formulated for high purity
- Good transmittance and higher temperature resistance
- Low hydroxyl (-OH) content
219
- Virtually ozone-free (or germicidal) quartz tubing that can help transmit UVA and UVB rays while blocking the deep wavelengths that cause ozone generation in lighting applications
- An excellent consideration for disinfectant applications and various UV treatments
254
- Lamp tubing that requires maximum visible transmittance with virtually complete UV protection
- An excellent consideration for applications requiring UVB and UVC radiation blockage
021 and 022
- Ultra-high-purity synthetic fused silica with low hydroxyl content; can exhibit exceptional solarization resistance and high transmittance in the deep UV range
Seal Glass
Momentive's seal glass is comprised of quartz rod material used as filler to weld quartz to metal, typicallyresulting in a successful welding resistant to thermal cycles. Available grades are GSG-1, GSG-3 and GSG-4 with graded coefficient of thermal expansion.
