Mail room threats can cost businesses up to $400,000 per day in lost productivity.

PathSensors’ breakthrough CANARY technology accurately detects threats such as anthrax, ricin and Ebola – at a fraction of the cost of alternative technologies.

• Used by top government and commercial mail screening customers
• Integrates with x-ray, chemical and other threat detection technologies
• High sensitivity, and ultra-low false alarm rate
• Perfect for rapid testing of unknown substances or high volume threat monitoring


BioFlash™ MailGuard System

Turn-key mail screening solution

PathSensors introduces the BioFlash™ MailGuard System. This biological testing unit can test both packages and standard mail, using forced airflow within the downdraft booth. A hose feeds the air to the BioFlash™ device for testing.

Comprehensive threat detection, low cost of ownership

PathSensors’ CANARY technology – originally developed by MIT – is a gamechanger for bio-threat detection. Unlike older technologies, CANARY detects pathogens faster and more economically.

  • • High sensitivity: 100 – 1000 CFU
  • • Fast: 5 minutes to result
  • • Flexible: detects +25 pathogens
  • • Low cost

The BioFlash™ MailGuard System consists of a testing unit, down flow booth, mail jogger, and compact medical refrigerator and requires standard 110v power to operate. The biological testing unit has the ability to connect to the Internet via an optional tethered laptop computer, which permits remote system diagnostics and secondary testing confirmation as needed.
