| Installed function | Provide a chemically durable, cleanable and optically suitable interface for samples, heat or fluid handling. |
How the Drawing Changes the Processing Plan
Base pages do not assign one universal process or tolerance. ANTGLASS selects cutting, drilling, CNC machining, grinding, lapping, polishing, cleaning and inspection steps from the drawing.
| Planning area | What to review |
|---|---|
| Candidate operations | Saw or thermal cutting, end grinding, chamfering, fire polishing, OD/ID calibration, drilling and cleaning |
| Material response | Material- and grade-dependent; qualify cutting, grinding, drilling, lapping and polishing against fracture and surface requirements |
| Feature geometry | Side ports, vents and custom connections are possible; hole size and wall ligament need tube-specific review |
| Edge and surface finish | Saw cut, fire polished, ground square, chamfered or ground-and-chamfered |
| Application conditions | Hotplate, flame, oven or thermal cycling conditions require a material-specific limit. |
| Inspection route | OD/ID metrology, wall and ovality measurement, end squareness, bore visual inspection and leak test when assembled |
Information Required Before Quotation
State the drawing revision, exact material or approved alternatives, dimensions, quantity, feature geometry, edge and surface requirements, operating conditions and the acceptance method.
| Decision area | What to confirm |
|---|---|
| Optical function | Define wavelength, path length, fluorescence/background and required clarity. |
| Thermal environment | Hotplate, flame, oven or thermal cycling conditions require a material-specific limit. |
| Chemical exposure | List acids, bases, solvents, detergents and decontamination method. |
| Mechanical load | Fixture load, pressure/vacuum and repeated handling determine thickness and edge protection. |
| Pressure or vacuum | Laboratory Equipment Glass: Define when the component forms a pressure or vacuum boundary |
| Edge condition | Chip-free handling edges; optical faces must be free of residue and scratches at the stated quality. |
| Surface condition | Chip-free handling edges; optical faces must be free of residue and scratches at the stated quality. |
| Cleaning | Follow reagent-specific laboratory cleaning; rinse residues completely and avoid HF/hot alkali exposure unless the selected material is qualified. |

Failure Risks and Inspection Focus
Inspection is tied to the functional dimensions and surfaces shown on the approved drawing; generic catalogue values do not replace project acceptance criteria.
| Review item | Project-specific focus |
|---|---|
| Product design risk | End chips, ovality, thin wall at side ports, fire-polish distortion and chemical attack |
| Product inspection | OD/ID metrology, wall and ovality measurement, end squareness, bore visual inspection and leak test when assembled |
| Application failure modes | Chemical etching, thermal shock, path contamination, tube-end chips and seal leakage. |
| Application inspection | Dimensions, visual cleanliness, spectral baseline, leak test where fluidic and thermal-cycle validation. |
| Acceptance method | Transmittance Measurement: Compare calibrated result with the drawing, purchase order or approved test specification |
