Review on Disposable Graduated Essential Scientific Experiment by Jermaine Krishnamoorthy

I bought these pipettes to use with my nutrient solution that I put in water for my tomato plants. So far it seems that about 1 in 10-15 has a manufacturing defect that causes the pipettes to not hold the liquid properly. Because of this, it can be frustrating to get everything ready and grab the iPad only to be unable to do what needs to be done. For example, adjusting my nutrients/PH so the liquid flows straight out of the tube. Besides, it fits me well. One of the sneaky complaints would be that I want them to tell you how to properly measure the amount of liquid in your paper. And/or how to properly put it on paper so that it can be measured. If you're looking for a quick and easy way to add a small amount of liquid, such as Less than I would use an eyedropper if I had nothing else. I am currently looking for a better way to measure nutrients more accurately and quickly.
