Finally, first responders have a quick and easy way to determine whether a suspicious powder is a likely bio-weapons agent, or not. Individual disposable presumptive tests that identify potential threat-agents such as suspicious powders – within 30 seconds, identify whether a substance is a probable bio-weapons agent or an innocuous powder. Collect the sample by simply dabbing the sample tip on the suspect material; analyze the sample by cracking the built-in ampoules and watching for the specified color change. BioScreener™ can eliminate the threat posed by a suspicious powder in seconds. Instead of shutting down an area for hours or days pending results of an analysis, first responders can identify a suspicious powder as a non bio-agent in seconds.
