Test method: The Peracetic Acid CHEMets® test kit (0 to 1 and 0 to 5 ppm) employs the DPD chemistry. The sample is treated with an excess of potassium iodide. Peracetic acid oxidizes the iodide to iodine. The iodine then oxidizes DPD (N,N-diethyl-p-phenylenediamine) to form a pink colored species in direct proportion to the peracetic acid concentration. Various oxidizing agents such as halogens, ferric ions and cupric ions will produce high test results. Hydrogen peroxide does not interfere with this test if present at levels comparable to the peracetic acid levels.

Simple to use benchtop meter for easily measuring pH and ORP.

MultiCan® Barrier containers offer a six-layer technology which makes this container a perfect fit for oxygen-sensitive contents and for liquids tending to permeate, such as non-polar hydro-carbon compounds. EVOH barrier containers are particularly suitable for flavors and fragrances, but also for alcohols, paints and coatings, additives, as well as solvents and cleaning agents.

The Go Direct Radiation Monitor detects alpha, beta, gamma, and X-ray radiation.
