Put your household cleaners to the ultimate scientific test! How effective are your daily sanitizing habits against invisible surface microbes? The Zone Defense Lab turns your living space into a real-world microbiology testing ground. This comprehensive kit uses a 5-plate experimental matrix to establish a dirty 'control zone' on a high-touch surface and map out four distinct cleaning grids to test the provided vials of distilled vinegar, concentrated soap, mild bleach, and isopropyl alcohol. By cleaning each zone, wiping it down with the provided lint-free lab wipes, and swabbing the surfaces once dry, you will visualize exactly how different chemical agents disrupt or eliminate microbial colonies. WARNING: Always test cleaners individually in their designated zones. NEVER mix, combine, or cross-contaminate any of the provided cleaning solutions or household chemicals together, as mixing household agents can trigger hazardous chemical reactions and produce dangerous fumes. To ensure a frustration-free experience, we've included a full duplicate set of 5 extra plates, plenty of extra swabs, and disposable laboratory gloves, giving you complete insurance against cross-contamination or the freedom to run a whole second experimental trial! Includes comprehensive zone-mapping worksheets and colony-tracking data charts.
