Dissolution Tester
Dissolution Tester
The RCDY-B is a dissolution testing instrument engineered to evaluate the release rate and extent of active ingredients from tablets, capsules, and other solid dosage forms into specified media. It helps verify whether manufacturing processes and product quality remain consistent and reliable. The unit accommodates six paddles or baskets, and operating parameters can be preset and stored automatically. It offers rapid heating with high precision and convenient temperature correction. A timer provides three operating modes—timing, timing, and cycle. Automatic protection and multiple fault alarms ensure safe operation. Speed is adjustable from 25 to 200 rpm with 1 rpm resolution, and temperature is regulated from ambient to 45.0°C with accuracy of ≤±0.3°C. Power supply is customized to order.
Features:
1. The dissolution tester accommodates six paddles or baskets simultaneously, enabling multiple parallel tests for efficient and reliable pharmaceutical dissolution rate analysis.
2. Operating parameters can be preset and stored automatically, ensuring convenient and reproducible dissolution testing across multiple runs in pharmaceutical quality control.
3. The tester features rapid temperature rise, high precision, and convenient temperature correction, ensuring accurate and reliable dissolution testing in pharmaceutical applications.
4. The timer provides three selectable working states including timing and cycle modes, ensuring flexible operation across diverse dissolution testing applications.
5. Equipped with automatic protection and multiple fault alarms, the tester ensures safe and dependable operation during dissolution testing in pharmaceutical applications.

Applications:
1. Pharmaceutical Quality Control and Batch Release Testing: Evaluates dissolution profiles of tablets and capsules to verify production consistency and support batch release under USP <711> standards.
2. Generic Drug Development and Bioequivalence Studies: Compares dissolution profiles between generic and reference products to support bioequivalence assessment and regulatory submissions.
3. Extended-Release and Modified-Release Formulation Development: Tests sustained-release, enteric-coated, and controlled-release dosage forms using USP Apparatus 1 (basket) and 2 (paddle) methods.
4. In Vitro-In Vivo Correlation (IVIVC) and Formulation Screening: Establishes predictive models linking dissolution data to pharmacokinetic outcomes, guiding excipient selection and process optimization.
