708-DS Dissolution Apparatus - SPECIFICATIONS

Significance of the Topic

Dissolution apparatuses play a pivotal role in assessing drug release rates and ensuring consistent product quality in pharmaceutical development and quality control.

Objectives and Apparatus Overview

The Agilent 708-DS Dissolution Apparatus is engineered to accommodate both manual and automated testing workflows, offering scalable options for enhanced throughput and productivity without compromising robustness or ease of use.

Methodology

The system operates under controlled ambient conditions (5–40 °C, ≤ 80% RH), maintaining bath temperatures from ambient + 5 to 55 °C with ± 0.1 °C probe accuracy and limiting evaporation to under 1%. It employs stainless steel paddle and spindle assemblies, agitating samples at 10–250 RPM (± 1% accuracy above 25 RPM, ± 2% at lower speeds) selectable via an integrated touchscreen.

Instrumentation Used

• Agilent 708-DS Dissolution Apparatus with motorized drive and stainless steel spindle shaft
• Built-in LCD touchscreen for real-time control
• Optional modules: Autosampling manifold, Dosage Delivery Module, handheld temperature probe, printer

Main Results and Discussion

The apparatus demonstrates reliable temperature control and minimal evaporative loss (< 1%) to ensure reproducible dissolution profiles. Its wide input voltage range (90–250 V, 50–60 Hz) and modular power requirements facilitate deployment across diverse laboratory environments. Scalability options enable progressive automation and integration of sampling features.

Benefits and Practical Applications

• Configurable setup supports both R&D and QA/QC laboratories
• Incremental automation improves throughput and reduces manual intervention
• Robust environmental control enhances data precision and repeatability

Future Trends and Potential Applications
