  • 100% UNATTENDED - Run a series of dissolution tests without any operator action required.
  • FILTRATION - Powerful piston pumps to push through fine filtration down to 0.2 microns for LC analytical finish.
  • BENCHTOP - Full dissolution automation on your standard laboratory bench with compact footprint modules.
  • COMPLIANT - Proven compliance with USP, Ph.Eur., and other Pharmacopeia requirements.
  • ANALYZE - Seamless integration of double beam or diode array UV-Vis spectrophotometers.



Samples in rack for dissolution tester

The best of both worlds.

The combination of UV-Vis online measurement and offline sample collection provides a highly flexible fully automated dissolution system. Samples read by the integrated UV-Vis can also be collected. Runs with UV-Vis analysis and/or sample collection can be batched together in any order. Regardless of analytical finish type, this system is ready to go.

The fully automated dissolution benchtop tester AT MD uses automated AutoLift™ cannulas to simultaneously withdraw samples.

Increase Productivity.

Automated dissolution improves the productivity of a lab creating walk-away-time for operators - allowing more time for mission-critical activties such as method development, process validation, data checking, and verification. Reducing cycle times and completing more work with existing resources.

Seamless method transfer.

The strategic implementation of laboratory automation is helping many companies to remain competitive. By placing automation in both R&D and Quality Control (QC) departments, some companies have created a seamless method transfer process, helping reduce the time-to-market for new products.
