Applications Expanded for Agilent 400-DS

With the development of novel dosage forms, dissolution testing requirements for combination medical devices becomes continually more important. While initially designed for the testing of drug-eluting stents, the Agilent 400-DS has evolved to fulfill requirements. It can test products including medicated contact lenses, pacemaker leads, implants, and polymeric rings. As many of these tests are performed over long time periods, the 400-DS combines the traditional USP apparatus 7 requirements with innovative design attributes that make it ideal for such experiments.

  • Small volume dissolution (5 or 10 mL) with media change flexibility—low amounts of API released over an extended time requires concentrations to be maintained at an acceptable level of detection
  • Evaporative control—sealed sample cells eliminate evaporative loss for the test duration
  • Solvent usage—certified for use with MeOH and EtOH as dissolution media
  • Temperature ramp capability—capable of performing accelerated dissolution studies to reduce overall testing time up to 55 °C
  • Custom holders—if none of the dozen current sample holders fits the application, Agilent offers investigative assistance to design a holder suitable for your specific product

Utilization of the 400-DS typically begins in an R&D setting in early stages of product or method development. The system allows for testing of as little as one or up to 13 samples per test with integrated automation capabilities to minimize manual intervention. Once the method is validated and the product is on the market, the compendial and compliant nature of this instrument eases the transition to the more regulated quality control laboratory.

A large part of this solution is the 400-DS Dissolution Workstation Software. The latest version, 1.7, has been updated to include enhanced e-signature capabilities and automated database backups. This makes it even more suitable for your 21 CFR Part 11-compliant environment.
