NanoLogix Inc., focused primarily on rapid diagnostics, is pleased to announce independent tests showing extraordinary success in testing of a revolutionary new packaging technology for the long-term, room-temperature storage of Petri plates used for bacteria detection. Tested with Anthrax as the reference bacteria, and designed for use in detection of a multitude of bacteria, this achievement may be the biggest single improvement to century-old Petri-dish-based technology in decades.
NanoLogix nitrogen-charged FlatPack Petri plates stored at room temperature for six months provided growth and detection of Anthrax equivalent to competitor’s new Petri plates, according to results of third-party testing conducted by a large independent laboratory. The competitor’s product delivered degraded results after just two months, the lab said, citing results after testing had reached a six-month comparison point. All tests were conducted using Tryptic Soy Agar (TSA), a world standard nutrient agar for bacterial detection. The tests also demonstrated an astonishingly reduced time for results to 14 hours for detection of Anthrax with NanoLogix FlatPack TSA, compared to historic norms of 24 hours using the competitor TSA.
FlatPack room-temperature pre-servation technology leapfrogs current standards, under which TSA Petri plates remain usable for only three months in cold storage – that is, 2 to 8 degrees Centigrade, or 36 to 46 degrees Fahrenheit, according to NanoLogix. FlatPack technology eliminates the need for refrigeration of TSA and extends the usable life of the TSA agar by multiples of what is available from competitors. In addition, FlatPack technology provides for easy visibility of all ten plates per pack for quality inspection, and reduces or eliminates breakage during shipping and storage. After shipping tens of thousands of plates, NanoLogix has been told by customers that not a single plate has broken.
The testing showed reduced results for the competitor’s Petri plates after the first two months of testing at room temperatures. At that point, NanoLogix Petri plates provided results essentially identical to new plates. After four months at room temperature, the nutrient agar in the competitor’s Petri plates had completely dried out and was unusable for detection, while NanoLogix’s Petri plates again provided identical results to new plates, the third-party lab said.
After five and six months at room temperature, due to the desiccated nature of the agar in the competitor’s Petri plates, the lab changed comparison for control purposes to compare NanoLogix’s Petri plates to the competitor’s fresh, just-delivered nutrient plates. At both data points, NanoLogix’s Flatpack-preserved Petri plates provided the equivalent in detection results to fresh Petri plates.
The current testing process, a follow-up to the successful one-year cold storage tests for NanoLogix TSA that were completed in 2012, will continue for an additional six months.
