Process timeline
From request to release
A service job is most reliable when each handoff is visible. The timeline below gives procurement, quality, and bench teams a shared view of what will happen before an instrument returns to use.
1Scope review
Confirm instrument family, serial number, use case, target accuracy, acceptance range, and any GMP, CLIA, CAP, or internal SOP obligations that shape the work.
2Service action
Perform calibration, repair, preventive maintenance, cleaning check, or application adjustment with notes that show what was changed and why it matters.
3Evidence package
Return certificates, service reports, tolerance notes, and recommended next interval so the quality file does not rely on memory or informal email.
4Follow-up
Review recurring failures, user technique issues, spare needs, and service cadence so the next intervention is planned before uptime is at risk.
