Milliflex® Quantum Rapid Detection System

Milliflex Quantum Rapid Microbial Detection System
Milliflex Quantum Rapid Microbial Detection System

Principle: Universal enzymatic fluorescent staining of viable and culturable microorganisms.

Automation: No

Approvals: Rapid microbial methods need to be validated. The Milliflex® Quantum system overcomes validation challenges by offering a solution based on minimal change to the compendial tests.

Suitability: Raw material (media, buffers, pharmaceutical ingredients, water) in-process samples (bioburden prior to sterilization, CIP/SIP, cell culture/fermentation samples,  fermentation media, manufacturing buffers, intermediate process samples)

Capital equipment required: Yes


The Milliflex® Quantum System is a rapid fluorescent-based technology designed for fast quantitative detection of microorganisms over a broad range of filterable matrices. This easy-to-use and simple system uses industry-standard membrane filtration techniques to detect viable and culturable microorganisms down to 1 CFU per sample. Test results are also comparable to your current microbial test results, which facilitates validation of this rapid system in any laboratory. The non-destructiveness of this method also allows you to identify any microorganisms detected during the initial fluorescent count, using your current ID methodology.

Key Points:
  • Detection times for most microorganisms between 8 – 48 hours
  • Easy-to-use and simple workflow, requiring minimal training
  • Compatible with any ID technology
  • Results comparable to compendial method, facilitating Milliflex® Quantum validation
  • Economical, robust system
  • Compact hardware
