I have personally always liked the ones from Sigma and have found them easy to use. The only real trouble I have had was with the test regions occasionally falling off with dunking the strips. You can usually solve that by instead adding a few drops of the
material to the strip with a pipet. Color change can be inhibited if the solvent is not mostly removed before adding the water. Sometimes waiting a little longer before adding the water can help, or giving it a good shake before adding the water for materials
that are not particularly volatile.

Time to replace my peroxide test strips and I have found a variety...the Quantofix are kind of the "brand name" but I find they are difficult to read with organic solvents...yes, you put a drop of water on after the dunk in the ether or whatever, but..
So has anyone tried (and liked, or hated) the JT Baker TESTRIPS for Peroxide? How about Haztech Hazcat strips? MQuant from Sigma?
Thank you for your pro and con views on any of these...best,Margaret
