It may have been constructed before 9/11 .... just practicing the NPR school of journalism.
I wish we had a better picture of those chemicals. The labels likely have information about expiration dates and such. Many are like volitile with short shelf lives - it'd be easy to either read the label or perform tests to see if the reagents are still new. Seems like it'd be easy to see if this has been around since the 90's or if it's new. But, I'm sure our guys are doing all that work as we speak.
