Standard Features of Dissolution Tester DS 8000 (Basic)
  • Advanced, Micro-Controller based: User-friendly, complies with current USP, BP, IP & EP specifications.
  • Splash waterproof keyboard: Alphanumeric polyester soft keys for keyboard.
  • Moulded water bath with 6+2 (3+1 & 3+1) vessel configuration enables  comparative studies.
  • External vibration free Water Circulator: for uniform water circulation, with audible,  low water level alarm, with indication on display for safety.
  • Mono shaft design with automatic adjustment for 25 mm depth setting with easy changeover between Apparatus I & II eliminates routine height validation as per USP.
  • Paddles, Baskets and Vessels are laser  marked with serial numbers  for  traceability. 
  • Tablet dispenser - drops 6 dosage form at single instance.(Optional)
  • Low Evaporation Lids: The conical shape low evaporation recovery lids reduces media loss during long run.
