Conostan® D-Series® Blended Standards
Conostan D-Series standards are available directly from SCP SCIENCE. Each D-3, D-12, and D-19 standard is furnished with a certificate of analysis.
Conostan is the original source of D-Series standards. More than 30 years ago, the U.S. department of Defense's Spectrometric Oil Analysis Program Standards Committee required standards for its wear-metals-analysis programs. With no reliable commercial source of metals-in-oil standards, Conostan's research department set to work in developing a reliable standard. The result was Conostan's uniquely superior product chemistry, which was adopted by the Department of Defense for its D-Series standards.
As with all Conostan products, you are guaranteed that the D-Series of standards are extremely stable and accurate.
