I ordered these standards over a month ago in anticipation of an upcoming project. I'm just getting to the project and needing to use the standards. While checking my turbidimeter I realize that it consistently won't stay in calibration. Upon further inspection I realize the Standards that I ordered on January 31 expired the prior December. These standards degrade with time, thats why they are so expensive. Now I'm stuck with $300 wasted and past my return window.
