SOTAX Equipment We Repair — By Category
SOTAX Product Lines We Repair
Our engineers are trained on the full SOTAX product range. Below are the major product families we service.
SOTAX Dissolution Apparatus (DT50, AT7, CE7)
Automated dissolution testing systems with paddle, basket, and rotating cylinder options. Common faults include motor encoder failures, temperature sensor drift, sampling valve blockages, and peristaltic pump wear affecting dissolution profile accuracy and batch release timelines.
SOTAX UV-VIS Spectrophotometer (UV-Xspect Pro)
High-precision UV-VIS detectors integrated with dissolution testers for real-time API concentration measurement. Typical issues include lamp aging, wavelength calibration drift, optical cuvette fouling, and detector non-linearity causing failed dissolution test acceptance ranges.
SOTAX Autosampler & Sample Handling (AUTOS, eluent prep units)
Automated sample collection and injection systems for high-throughput dissolution testing. Repair focuses on syringe seal degradation, needle clogging, carousel positioning errors, and software communication failures between autosampler and dissolution apparatus.
SOTAX Control Software & Data Systems (Sotax 2.5, PEAK)
Windows-based instrument control, data acquisition, and GMP-compliant reporting software. Issues include database corruption, loss of electronic signatures, network interface card failures, uninterruptible power supply (UPS) integration faults, and validation documentation gaps.
SOTAX Peristaltic Pump & Tubing Systems
Precision pump units and silicone tubing for sample delivery and media circulation in dissolution baths. Common wear issues include pump head seal leaks, tubing rupture, pressure sensor malfunction, and flow rate inconsistency impacting dissolution medium homogeneity.
SOTAX Temperature Control & Bath Systems
Precision water bath thermostats and heating blocks maintaining 37°C ± 0.5°C for dissolution testing. Faults include RTD sensor failure, immersion heater burnout, thermostat relay sticking, and temperature overshoot causing failed batch acceptance.

Common SOTAX Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SOTAX equipment arriving at our workshop.
- ✓Temperature sensor RTD drift or complete failure — SOTAX dissolution apparatus relies on precise ± 0.5°C temperature control per USP/BP/EP guidelines. RTD Pt100 sensors degrade due to immersion in buffer solutions, causing calibration drift. Sudden failure occurs when sensor ceramic element cracks or connector corrosion interrupts signal.
- ✓Autosampler needle clogging and injection pressure rise — SOTAX autosampler needles accumulate API precipitate, excipient residue, or buffer salt crystals over repeated sampling cycles. High injection pressure triggers pressure sensor alarms, halting automated dissolution testing and requiring manual restart with data integrity questions.
- ✓Peristaltic pump head seal leakage and cross-contamination — Repeated dissolution testing with aggressive buffers and organic solvents degradates silicone seals in SOTAX peristaltic pump heads. Leakage allows buffer to contaminate the pump motor compartment, corroding electrical contacts and risking cross-contamination between test batches.
- ✓UV-VIS spectrophotometer wavelength calibration drift beyond tolerance — SOTAX UV-Xspect detectors require wavelength calibration at 200 nm, 254 nm, and 280 nm using holmium oxide reference solution per USP <857>. Optical bench vibration, lamp aging, or software rounding errors cause drift, leading to failed dissolution profile acceptance ranges.
- ✓Data Management System (DMS) database corruption and electronic signature loss — SOTAX Sotax 2.5 and PEAK software store dissolution data in SQL databases. Unplanned power loss, network interruption, or virus infection corrupts database tables, causing loss of electronic signatures, audit trails, and batch release data. GMP compliance is immediately compromised.
- ✓Motor encoder failure and paddle/basket position loss — SOTAX dissolution apparatus motors drive paddles and baskets via stepper motors with rotary encoders monitoring position. Encoder wear, connector corrosion, or firmware mismatch causes position error messages, preventing apparatus startup and halting entire dissolution schedule.
