DFC-120SP: Semi-Automated Dissolution Test System

The DFC-120SP from Pharma Test is a semi-automated dissolution testing system designed to streamline the dissolution testing process for tablets in pharmaceutical applications. This system is particularly valued for its efficiency and precision in sample collection and handling.

Key Features and Components

1. Dissolution Bath (PTWS 120D or PTWS 120S)
   • PTWS 120D: Features 6 stirred positions with a uniform speed.
   • PTWS 120S: Allows individual speed control for each stirrer, offering configurations such as 2×3 or 3×2.
   • Both models include built-in vessel centering, programmable sampling times, and an automated temperature check and log.
2. Multi-Syringe Pump (PT-SP8)
   • Equipped with up to 8 high-precision glass syringes (10 ml each), driven simultaneously by a stepper motor.
   • Syringes are connected to a 3-way pinch valve for precise media flow control.
3. Fraction Collector (PTFC-2/8)
   • Automates the collection of samples into vials, ensuring accurate and reproducible sample volumes.
   • Includes features such as automated tubing pre-flush, sample collection, and tubing emptying between cycles.
4. Automated Operations
   • Automates the most labor-intensive stage of dissolution testing: sample collection.
   • Programmable sampling times help eliminate human error, providing high reproducibility and accuracy.
5. User-Friendly Interface
   • The system can be operated without external PC software, with optional use of WinDiss ARGUS dissolution software for enhanced control.
   • Data entry and method programming are managed via a touch screen on the dissolution bath.

Technical Specifications

• Display: 6-inch color LCD, 320×240 pixels.
• Stirrer Speed: 25 – 250 RPM with ±2% accuracy.
• Temperature Control: Range of 25 – 45°C with ±0.2°C accuracy.
• Vessels: 1-liter borosilicate glass vessels with ultra-low evaporation design.
• System Tools: Includes MonoShaft™ stirrer design, various USP/EP apparatus tool adapters, and individually coded vessels.

Advantages

• Efficiency: Automates sample collection, reducing manual labor and time.
• Accuracy: Ensures high reproducibility and standardization in sampling volumes and times.
• Convenience: Allows for unattended operation after the dissolution run starts, with all necessary sample handling automated.
• Compliance: Fully compliant with USP <711/724> and EP <2.9.3/4> standards.

Applications

The DFC-120SP is ideal for pharmaceutical laboratories seeking to improve the efficiency and accuracy of their tablet dissolution testing processes. It is particularly beneficial for applications requiring strict adherence to regulatory standards and high-throughput testing.
