Powder Chemistry Packs are the latest advancement in the realm of colorimetric measurement. They are pre-measured and ready-to-use.

Just add the powder pack to the sample, allow it to dissolve and react, then get your measurement. It is that simple! For added convenience, these powder packs can be used on other manufacturers colorimeters. We have a wide range of EPA equivalent chemistries available, all of which are preprogrammed into the Thermo Scientific AQ4000. Each powder chemistry pack contains 100 tests.
