Below is a descriptive list of our high purity inorganic brands:

Puratronic inorganic compounds

The Puratronic line of base metal salts, solutions, and pure elements is the leading choice of pharmaceutical and high technology companies needing the basic building blocks for many research and development processes. Each Puratronic compound has a minimum purity of 99.99% (metals basis) and each is backed by a lot-specific certificate of analysis. Our Puratronic production labs are in continuous operation and can produce batch sizes from a few grams up to hundreds of kilograms. We also have the capability to custom produce compounds of different purities and mesh sizes.

Anhydrous salts

Thermo Fisher Scientific provides a comprehensive line of ultra-dry, anhydrous salts, the first choice for air- and moisture-sensitive research applications.

Ultra-dry materials are manufactured under exacting conditions to ensure that impurities and water content are in the parts per million range. High purity starting materials are used in the manufacturing process, resulting in typical overall purities of 99.9% to 99.999%. Typical analysis is by Glow Discharge Mass Spectrometry (GDMS), which ensures high accuracy and detail. All anhydrous salts are ampouled under argon, and most are available in -10 mesh bead and powder form. Anhydrous salts are available in multi-kilogram quantities.

REacton rare earth products

Through a combination of strong sourcing and manufacturing capabilities, Thermo Fisher Scientific has become a leading global producer of rare earth metals, alloys, and compounds, including a wide range of oxides, chlorides, fluorides, nitrates, and trifluoromethanesulfonates. The REacton brand line, recognized as a benchmark for high purity rare earths, includes scandium and yttrium as well as the entire lanthanide series of elements: neodymium, cerium, europium, ytterbium, lanthanum, and gadolinium (excluding promethium). We also offer a range of specialty rare earths, such as sputtering sources, magnetostrictive rods, and custom preparations for numerous laboratory research applications. Custom blends and solutions are also available. Custom synthesis and special packaging services are available to meet your specific requirements. All of our rare earth products ship with a comprehensive Material Safety Data Sheet, and REacton brand products always include a Certificate of Analysis. We recognize that prompt delivery is crucial, so we always strive to meet promised delivery dates. Virtually all products listed are in stock for immediate delivery, many in bulk.
