Expertise and Experience in Manufacturing High Purity, High Quality Chemicals

Strem Products Tree

Our mission is to provide specialty chemicals of high purity in a timely fashion. Quality is the most critical component of all products and services. Due to Strem's focus on quality, most products are of high purity, typically 99%, with some at 99.9999% metals purity.

Unlike a production environment, where QA procedures may identify non–conforming chemicals, in research the scientist typically relies on the supplier's quality procedures and documentation. If these are not properly conducted then poor quality chemicals may kill a great research idea! Strem utilizes a comprehensive range of analytical techniques tailored to each product to insure quality. All of Strem's catalogs, since inception, have listed “Color and Form” for every product, as these are primary indicators of quality.

Long Term Focus in Inorganics, Organometallics and Metals

Strem offers over 6,000 specialty products in the area of metals, inorganics, organometallics and nanomaterials. Its first commercial product was cobalt carbonyl, manufactured in Strem's high pressure autoclaves. The first catalog also contained catalysts/precatalysts and phosphorus ligands, which continue to be important classes of products offered by Strem. Product range includes:
