EI-DVI Model 912 Single Basket Dissolution Tester
Overview and Application
The Tablet Dissolution Test Apparatus Model 912 is a crucial instrument utilized for the determination of the active drug ingredient release rate in pharmaceutical formulations, including both tablets and capsules. It is specifically designed to comply with USP, BP, and IP specifications. This single test apparatus provides the necessary information to evaluate adequate bio-availability and formulate therapeutically optimum dosage forms, making it extremely useful for quality control and research and development in pharmaceutical laboratories.
Operational Excellence and Technology
The core of the Model 912 consists of a constant temperature acrylic water-bath in which the dissolution vessel is precisely placed. A specific dissolution medium, required for the tablet or capsule formulation, is added to the vessel.
The instrument achieves operational excellence through advanced control systems:
• Microprocessor Control: The system incorporates a microprocessor-based speed controller, ensuring the stirrer speed is accurately regulated and maintained with high precision.
• Accurate Temperature Management: The water-bath temperature is accurately maintained by a very sensitive thermostat, ensuring reliable testing conditions.
• Quality Construction: The apparatus is built with durable components, including a variable speed motor, a cylindrical basket, and a shaft with blades, all constructed from stainless steel.
The sophisticated micro controller, combined with its elegant design and advanced features, positions the EI-DVI 912 as a state-of-the-art dissolution testing device.
Key Advantages
• Highly Accurate and Easy to Operate.
• High Stirrer Speed Accuracy (controlled by microprocessor).
• Accurate Temperature Control (maintained by sensitive thermostat).
• Plays an important role in product development and quality control.
