CORROSITEX
)
Corrositex is an invitro test that determines chemical corrosivity and permits assignment of Packing Group classification for Class 8 corrosives. This test replaces the rabbit test of dermal corrosivity by providing a reliable means of mimicking this test. The proprietary core technology of the Corrositex test is based upon a biomembrane and chemical detection system, which becomes colored when exposed to potentially corrosive substances.
Why Use Corrositex
Because it will save you time and money.
- Time Savings: Unlike animal testing that can take 2 to 4 weeks, Corrositex testing can provide a Packing Group determination in as little as 3 minutes and no longer than 4 hours.
- Cost Savings: In a recent evaluation, one customer saved up to $50,000 annually, in shipping costs, for a single compound when using the Corrositex test to define the Packing Group instead of relying on pH. In addition to the reduction in shipping charges, additional cost savings are found in the areas of workplace safety and MSDS development.

The Corrositex testing system consists of a glass vial filled with a chemical detection fluid capped by a proprietary bio-barrier membrane, which is designed to mimic the effect of corrosives on living skin.
As soon as the corrosive sample destroys this bio-barrier, the fluid below changes color or texture. Users simply record the time it takes for the sample to break through the membrane. Then, depending on their needs, they can assign the proper U.N. Packing Group classification for U.S. DOT or EPA compliance, or use the data as a ranking tool or to substantiate marketing claims.
