Key benefits of Xelox® range include:

  • Reduced variability in results
  • Increased volumes of test data
  • Increased productivity
  • Greatly reduced analyst time spent on labour intensive processes
  • Significant reduction in Health and Safety issues including WR-ULD
  • Contained handling of drug product, minimising operator exposure
  • Upgrade paths throughout the Xelox range
  • Harmonised testing throughout the Xelox range

1 Series

The Xelox® 1 Series are analyst workstations. They automate individual stages of the particle size determination process. They improve data consistency by removing manual errors from key stages of the test sequence.

3 Series

The Xelox® 3 Series are semi-automated platforms. They automate the entire particle size determination process, including waste firing, dose collection, dose recovery, assay preparation, clean up and cup coating.

5 Series

The Xelox® 5 Series are fully automated systems. They offer 24/7 high throughput unattended operation.
