Restek UST Stock Solution, Creosote Oil Standard, 50,000 µg/mL in methylene chloride, 1 mL/ampul.

Whether you are processing environmental samples or petroleum products, testing pharmaceuticals or food, your laboratory cannot stand without a trusted source of high-quality organic reference standards.

Even using industry-leading chromatography products, you won’t get the results your customers demand without support from the finest reference standards available. Restek has an experienced team working two shifts per day to make sure that their reference standards offer you the extended shelf life, unsurpassed stability, and outstanding chromatographic performance you need to get your work done right.

Over 99% of Restek's reference standards are certified reference materials (CRMs), including both single-component and multicomponent mixes. Restek has also maintained ISO 9001 registration since 1994. Put another way, almost all Restek stock reference standards are officially recognized as being manufactured and QC tested under the world-class quality standards established by the International Organization for Standardization (ISO). Many laboratories are required to purchase CRMs to satisfy their own ISO requirements, but even if you are not, you can still benefit from the performance, reliability, and consistency of Restek reference standards.

Restek offers fully ISO-compliant documentation for their reference standards. Electronic and archived on Restek’s servers, certification for your stock or custom reference standards is available any time and from anywhere.
