This unit
The Stanford Research Systems MPA100 Optimelt is an automated melting point analyzer for precise determination of melting temperatures and ranges in synthetic and analytical chemistry laboratories. Using the capillary method - compatible with all major pharmacopeial procedures - it analyzes up to three samples simultaneously with microprocessor-controlled temperature ramping, integrated digital image processing for automated melt detection, and a touchscreen interface. The system operates unattended, with results automatically recorded and displayed for review.
It also functions as a general-purpose digital thermometer and timer.

Stanford Research Systems MPA100 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Stanford Research Systems MPA100. 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 MPA100 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.
