From the website it looks like they are selling these TSA-EL plates in boxes of 100 now not 50.
Cold storage 1 year
RT storage 6 months and will be tested for another 6 months. I wonder if RT testing will be successful at one year. That would be valuable for some users I think. Heck 6 months could be valuable ! No refrigeration, no breakage.
I picked up on that too, but didn't bother submitting the question to management since it doesn't matter due to BNP and BNF. My guess is that because the product is produced in a clean room environment, there is little chance for contamination that might slow down the detection of anthrax.
This is just one more little inducement to try out the basic Petri product. Check out the shelf stability and long life, see how even the plain vanilla product detects bugs faster, and get a trust level for the company. Then customers will be more inclined to give BNP/BNF a try as well, because it comes from a manufacturer they already know and respect. Come for the incremental improvement to a familiar product, stay for the revolutionary way it can be used.
