What's inside

A Radian®-focused look inside Copan’s Clinical Microbiology Automation Solutions brochure, highlighting automated disk diffusion AST, Mueller Hinton plate seeding, antibiotic disk application, plate imaging, zone measurement, expert interpretation support, and WASPLab® integration.


  • End-to-end disk diffusion AST automation: Radian® automates Mueller Hinton plate seeding, antibiotic disk application, robotic transfer to incubators, plate imaging, zone measurement, zone interpretation, and result output.

  • Radian® Expert System: Halo Recognition Algorithms measure zone diameters and apply interpretive rules to support susceptible, intermediate, or resistant result interpretation.

  • High-capacity in-line carousel: The antibiotic disk carousel sits along the WASPLab® track on a parallel redirection line, supporting flexible antibiotic selection and protocols using up to 8 disks per 100 mm plate.

  • Customizable interpretation rules: A flexible expert-system interface allows laboratories to adapt or customize rules, with direct communication to the rules database.

  • Built-in quality control: A dedicated vision system confirms disk dispensing and checks that the disk matches the selected protocol, helping support consistent AST setup.

  • Potential for earlier reading: When validated by the laboratory, Radian® has the potential for early susceptibility reading to support more timely AST results.

  • Part of Full Laboratory Automation: The full brochure also covers WASP®, WASPLab®, PhenoMATRIX®, Colibrí™, and WASP-FLO™, plus return-on-investment considerations for Full Laboratory Automation.
