TEMPO Challenge Test Automation Overview

Challenge Test automation with TEMPO increases throughput and delivers results faster, which increases flexibility and shortens the product development cycle.

TEMPO is an automated system for microorganism enumeration. It is miniaturized and an optimized MPN method (16 tube repetition) that allows quantification compliant with USP <1223> and ISO 11930.

Increased laboratory performance

With the rapid and fully automated TEMPO system, increase your productivity and improve your routine challenge test operations:

  • SIMPLIFIED WORKFLOW: No serial dilution and no plating
  • SECURED DATA: Full traceability is ensured with simplified audits and improved data quality
  • ENHANCED REACTIVITY: Free up time for investigation studies & quickly adapt to seasonal workload peaks
