Very High Level Peroxide Test Strips, Food Grade, up 10% Conc. (Vial of 50)
The Very High Level (VHL) Peroxide test strips are designed for semi-quantitative testing of "food grade" hydrogen peroxide solutions. They utilize highly durable PVC strips that turn one color: black. Therefore, the concentration is determined by how long it takes for the strip to change to black.
These VHL Peroxide test trips are suitable for hydroperoxides and ether peroxides. Polymeric peroxides are not detected.
Di-tert-butyl peroxide, dicumyl peroxide, or tert-butyl perbenzoate do not react (or will react with significantly reduced sensitivity).
