Automated dissolution testing system for 16 vessels
Maximize your laboratory throughput by conducting parallel dissolution tests with high-precision UV-Vis analysis, ensuring real-time results and compliance for complex pharmaceutical formulations.

Automates and Analyzes Pharmaceutical Dissolution Testing
The ATS Xtend™ Double UV On-/Offline Dissolution Tester from SOTAX offers an innovative solution for laboratories needing efficient dissolution testing of pharmaceutical and biotech formulations. This system is capable of automating dissolution analysis for up to 16 vessels simultaneously, utilizing high-precision double beam UV-Vis technology for accurate and reliable results. Its standout feature is the ability to alternate between online testing and offline sample collection with minimal system adjustments, enhancing flexibility.
Ideal for analyzing tablets, capsules, injectable suspensions, and other complex drug forms, it supports high-throughput operations to meet demanding production schedules. The Xtend™ system includes robust integration capabilities, sharing a single UV-Vis spectrophotometer and dual-rack sample collector across two dissolution baths, minimizing both financial investment and spatial requirements.
Configured with fully compliant systems that adhere to Pharmacopeia standards and 21 CFR part 11, it ensures stringent regulatory compliance. The equipment’s sampling flexibility, through various filtration methods, optimizes preparation for downstream HPLC/UPLC analysis, while the media and filter stations facilitate precise and efficient media preparation and filtration.
Engineered to reduce variability and improve productivity, the Xtend™ series supports scalable laboratory needs by simplifying the addition of modules without excessive validation requirements. Its compact design allows for easy cleaning and maintenance, further establishing it as an essential tool for pharmaceutical manufacturers and research institutions.
