Gauge Glass
Gauge/sight glass
Recommended route in the application record
Gauge Glass appears in the V4.1 recommended material route for Laboratory 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 | Define wavelength, path length, fluorescence/background and required clarity. |
| Temperature and thermal cycling | Hotplate, flame, oven or thermal cycling conditions require a material-specific limit. |
| Chemical and cleaning exposure | List acids, bases, solvents, detergents and decontamination method. |
| Mechanical and mounting load | Fixture load, pressure/vacuum and repeated handling determine thickness and edge protection. |
| Pressure or vacuum boundary | Laboratory Equipment Glass: Define when the component forms a pressure or vacuum boundary |
| Cleaning and handling | Follow reagent-specific laboratory cleaning; rinse residues completely and avoid HF/hot alkali exposure unless the selected material is qualified. |
