Hey everyone I have been trying to figure out what is going on with most recent bottle of reagent. I noticed that there is something floating around in the sample cuvettes after I put the reagent in. You will see the stringy looking stuff floating in the water column.I have some pictures but with the curved cuvettes makes pictures hard to get quality right. Let me know what you all think whats going on. I will contact Hanna and see what they have to stay and if it will cause any major differences in testing results.
