Automated weighing system for tablets
Ensure precision in pharmaceutical manufacturing by seamlessly integrating advanced weight testing directly with your tablet press, enabling real-time self-adjustment and preventing potential issues caused by weight drift.

Automates Continuously Weighing for Tablet and Capsule Production
The WT50 from SOTAX is a comprehensive, online weight tester designed for precision in pharmaceutical manufacturing. This system seamlessly integrates with various tablet press brands, automating continuous weighing for tablets and capsules. Featuring a high-precision weighing module, the WT50 operates with a vibration-resistant mechanism ideal for the demanding conditions of compression rooms. It handles a wide range of applications, from aspirin tablets to transdermal patches, ensuring consistent product weight for end-products such as gelatin capsules and extended-release pellets.
The WT50’s modular design supports easy integration, allowing for minimal space usage with gravity or venturi feeding options. It automates the determination of minimum weight in compliance with USP <41>, providing detailed reports for quality assurance. Sample collection capabilities are included for further lab testing, without increasing the system’s footprint. The WT50’s programmable cleaning intervals and elevated weighing platform reduce downtime and contamination risk, optimizing your production line with less manual intervention.
