DT-810 Dissolution Tester


JASCO offers the DT-810 Dissolution Tester, fully automated and designed for flexibility to provide dissolution testing of up to 8 samples with either the paddle method (standard) or the rotating basket method (optional).


System Description

The DT-810 Dissolution Tester features a unique circular design that provides uniform water temperature while utilizing a round heating element. The Direct-Center ™ automatic centering mechanism provides hands-free positioning of the dissolution vessels and drive shafts for accurate dissolution tests with high reproducibility. All components are controlled via PC using simple keystroke operations with a user friendly graphic interface.

System Features

  • Meets USP, EP and JP requirements
  • 21 CFR Part 11 compliant
  • Excellent temperature stability using the circular bath
  • Uniform temperature distribution between vessels
  • Easy to set up and maintain
  • Direct-center vessel centering for automatic alignment of vessels and drive shafts
  • Test vessels manufactured with precise tolerances for vessel dimensions
  • PC control for monitoring
  • Automated tablet dropping system for dosage loading
  • Automatic sampling tube positioning for the upper and lower positions
  • Amber bath & vessels for light-sensitive samples
