Review on Eisco Labs Phenylthiourea Paper Strips by Steven Bush

I recently purchased some paper strips for substance analysis from Industrial and Scientific, and Im very pleased with the results.When I tried this product, I found that it was easy to use and provided accurate and reliable readings. The strips are also very affordable making them a great choice for those looking for an inexpensive and effective way to test substances. The only downside is that they can be a bit difficult to store once opened if you don't have a suitable container. Overall, I highly recommend these strips to anyone in need of industrial-grade substance testing tools..
