This unit

The Stanford Research Systems MPA120 Optimelt is a fully automated melting point determination system that analyzes up to three samples simultaneously using digital image processing and PID-controlled temperature ramping. The instrument identifies clear points and onset of melt with 0.1 °C resolution across a range up to 400 °C, delivering repeatable results compliant with Pharmacopeia and GLP standards. Its compact aluminum oven design, built-in magnification lens, and wide observation window with internal illumination enable precise sample viewing without manual intervention.

Stanford Research Systems MPA120 — Repair & Calibration Service

Aumictech offers NIST-traceable calibration and repair for the Stanford Research Systems MPA120. Calibration covers calibration scope varies by instrument type: vacuum gauges are verified at multiple pressure points against NIST-traceable pressure standards; spectrophotometers at wavelength accuracy and photometric accuracy points; strain gauge indicators at bridge excitation accuracy and full-scale output accuracy; pH meters against certified buffer solutions at pH 4, 7, and 10.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.

Common Stanford Research Systems MPA120 faults: vacuum gauge filament failure (ionization gauges), spectrophotometer D2 lamp end-of-life, wavelength motor failure, strain indicator front-panel binding post corrosion, pH electrode conditioning failure. Most specialty laboratory instruments fail at their electromechanical interfaces first — vacuum gauge connectors and filament assemblies, spectrophotometer lamp housings and motor drives, strain indicator binding post corrosion. Component-level repair is standard; manufacturer support for legacy instruments is often limited, making third-party bench repair the practical path.
