CHEMetrics R-7540 CHEMets Dissolved Oxygen Refill, Rhodazine D, 30 Ampoules

for some reason the test turn purple and it doesnt match with the color on the sample reading table. (the color on the table is blue) is this a defective product? or did I order the wrong color by mistake? I was not aware of different colors for this test. thanks,

Some of the ampules came in broken. Then when I used it they were also purple and did not match the kit which is blue. They did refund my order though
