BioHawk LF®

Automated Biodetection and Bioidentification

BioHawk LF

The BioHawk LF® is an automated, integrated system for detecting, collecting and identifying airborne pathogens. BioHawk LF employs multiple world-class technologies: biofluorescent detection, cyclone-type wet collection, machine vision, and multi-analyte lateral flow immunoassay (LFIA) identification.

Fully automated Upon detection of a suspicious aerosol, the bioidentifier executes automatically, or may also be manually initiated if preferred. Test results are provided through an onboard display and serial digital data link.

Reduced use of consumables Assays are only performed when a bioaerosol has been detected, saving time and cost. This is in contrast to protocols where assays are run at fixed intervals or in batch processing where each batch must be tested before release.

Rapid results No lag between detection and testing - the entire process from the initial threat detection to results takes only about 20 minutes.

Accurate test analysis BioHawk LF employs sophisticated machine vision technology to ensure that tests are read with maximum accuracy, eliminating variables such as lighting conditions and imperfect human vision. Weak positive results that might have been missed by conventional methods will be correctly read. A strong positive may be identified early in the test protocol, shortening the time to results by several minutes.
