Oxidation Reduction Potential (ORP) Buffers, Standards & Solutions
Eliminate any concerns with mixing reagents, hazardous chemical exposure or disposal. Our oxidation-reduction potential (ORP) standards are premixed, without sacrificing on stability.
Our ORP standards have produced great results in ASTM™ round-robin testing and are specified in ASTM Method D1498. Where standards based on quinhydrone are only good for one day and those based on Zobell’s solution are only good for one year, the stability of our ORP standard gives it a two-year shelf-life.
