AVENIO Millisect System


The AVENIO Millisect System is an automated, high-performance tissue dissection system that enables precise and consistent recovery of formalin-fixed paraffin-embedded (FFPE) tissue areas of interest for molecular pathology. The system is optimized to fit easily into a variety of clinical workflow configurations, improves diagnostic testing results by reducing false negatives, and can help you efficiently extract more clinically relevant information from every sample.


  • Maximize clinical utility of tissue samples by identifying mutations missed with manual dissection and reducing false negative rates1,2 
  • Increase dissection efficiency and optimize results by capturing only clinically relevant cells1 
  • Improve lab workflow and minimize demands on staff by ensuring consistent sample capture through an automated, digitally assisted process3

Product Highlights


Digital annotation

  • Allows definition of multiple Areas of Interest (AOIs) on a single slide, without limits on geometry
  • Digitally-assisted alignment to reference slide for up to 4 serial slides
  • Intuitive software interface to guide user annotations

Automated milling

  • Faster process with fewer steps and no pre-staining
  • Precise milling displaces tissue AOIs as small as 250 µm2 using a rotating action
  • Automated consumable loading, reagent filling and unloading

Gentle recovery

  • Hands-free process minimizes potential for contamination 
  • Capillary action used to lift and recover AOIs after milling
  • No risk of burning or losing sample with gentle, non-laser optics

Comprehensive reporting

  • Electronic report file, including images, annotations and notes, exportable as a PDF 
  • Pre- and post-dissection image capture
  • Barcode scanning for improved chain of custody
