Gauge Glass
Gauge/sight glass
Recommended route in the application record
Gauge Glass appears in the V4.1 recommended material route for Scientific Instrument Glass, but the exact grade and assembly conditions still require validation.
Drawing and system validation
The material name does not certify the installed equipment. Grade, thickness, edge, surface, coating, mounting and service-condition validation remain project-specific.
Application Conditions That Control Material Selection
Optical, thermal, chemical, mechanical, pressure, sealing and cleaning requirements must be defined before this material route is accepted.
| Service condition | What to define |
|---|---|
| Optical or viewing requirement | Specify wavelength, path length, absorbance/background, scatter, fluorescence and surface quality. |
| Temperature and thermal cycling | Lamp/detector heat and sample temperature must not change path length or seal integrity. |
| Chemical and cleaning exposure | Sample, solvent and cleaning chemistry must be compatible with glass, coating and bond. |
| Mechanical and mounting load | Flow pressure, connector load and instrument clamping require a stable, low-stress window. |
| Pressure or vacuum boundary | Optical Instrument Window: Define when the component forms a pressure or vacuum boundary |
| Cleaning and handling | Use non-contact optical cleaning with verified solvent/coating compatibility; inspect for haze, sleeks and edge contamination. |
