Test Kit for Bacteria (E-Coli) in Water, Easily Check For Harmful Coliforms with Results in 10 Minutes And No Lab Analysis Required (2 pack)

The instructions were a bit difficult to know if you did it right. They said add 3 drops to the test tube, but 3 drops did not equal .40ml then add .1 ml water. The lines on the test tube were hard to read . After 10 mins the color strip showed no e coli, but I added more of the lystate than the instructions called for just to make .5ml total volume. So there was the nagging thought in my mind that I did it wrong thus a bad reading. The support people did promptly respond the next day. Long story short I ended up using Well Safe to treat the well so avoid the effects of e coli. in the water.

Used for a science project. Worked as advertised.
