I submitted a completed form on the Hanna website but have yet to receive a response.
Nitrate HR Reagent lot #H034 with an expiration date of 06/2027 is defective
Roughly 50% of the packets from the box, about every other packet opened, are clumpy and moist within the packet. It is impossible to get all of the reagent in the vial as it is stuck to the sides of the foil packet. When used it creates an orange color, instead of the usual pink, and the results are well below that of a normal packet.
Today’s test
Normal packet - 17.5ppm
Defective packet - .7ppm
If someone from Hanna could provide assistance, that would be fantastic.
