Drawing, Processing and Assembly Definition
Phase 6I does not import generic process capability numbers. Manufacturing and acceptance remain tied to the exact grade, geometry, quantity and drawing.
| Route item | Project-specific requirement |
|---|---|
| Typical component forms | Spectrophotometer flow cell, cytometry flow cell, cuvette-style cell or microfluidic window/body. |
| Application process route | Optical polishing, channel machining, bonding/sealing, precision cleaning and pressure/leak qualification. |
| Material-compatible processes | Precision cutting; CNC/ultrasonic machining where qualified; grinding; lapping; polishing; cleaning; inspection |
| Size and thickness | Channel, path length and sample volume are method-specific; no single generic thickness is valid. |
| Edge and surface zones | Micro-polished channel and clean optical faces; seal land cannot encroach on the beam. |
| Drawing release | For Flow Cell Window glass processing for Optical Glass, identify exact grade, datums, clear aperture, mounting and sealing lands, edge profile, surface quality, coatings, quantity, inspection and packaging. |
Quality Controls for Flow Cell Window glass processing for Optical Glass
Inspection must verify both the material-dependent characteristics and the installed application requirement.
| Risk or control | Application × material focus |
|---|---|
| Application failure modes | Bubble trapping, leakage, path error, fluorescence, residue and channel blockage. |
| Material-specific limits | Grade, thickness, surface state, wavelength and temperature conditions must not be generalized |
| Inspection method | Channel microscopy, path-length and spectral baseline, pressure/leak test and flow validation. |
| Standards and system validation | ISO 10110 parts for optical faces; ISO 20485:2017 may support tracer-gas leak testing of a sealed assembly when applicable. |
| First article | For Flow Cell Window glass processing for Optical Glass, validate fit, optical or viewing performance, mounting, cleaning and the most critical service condition before batch release. |
