• Acids & Bases
    Acids & Bases
    Compounds that dissolves in water to yield hydronium ions (H3O+) in the case of acids or hydroxide ions (OH−) in the case of bases.
  • Biosynthesis
    Reagents used in oligonucleotide synthesis, as well as other biological synthesis.
  • Buffers
    Substances that maintain a constant pH over a given range by neutralizing the effects of hydrogen ions.
  • Certified Reference Materials
    Certified Reference Materials
    Research Chemicals/Products/Certified Reference Materials
  • Chromatography Supplies
    Chromatography Supplies
    Products designed to support the separation of a mixture.
  • Eluents & Additives
    Eluents & Additives
    Products that move analytes through the chromatograph, also known as the mobile phase. In liquid chromatography, the eluent is the liquid solvent; in gas chromatography, it is the carrier gas.
  • Karl Fischer Titration
    Karl Fischer Titration
    Titration method that uses coulometry or volumetry to determine trace amounts of water in a sample.
  • Labware
    Lab equipment and supplies for science laboratories, including safety equipment, solvent labware, and well plates.
  • Metals & Elements
    Metals & Elements
    Substances that consist of a single element or are alloys, as well as products designed to identify and quantify metals and other elements.
  • Prepared Solutions
    Prepared Solutions
    Highly customizable blends of high-purity solvents, reagents and buffers that are produced to precise specifications.
  • Primary Reference Fuels
    Primary Reference Fuels
    Iso-octane, n-heptane, toluene, or 80 octane blends used in a test engine to determine the octane rating of gasoline.
  • Reagents
    Chemicals added to a system to cause a chemical reaction. Includes reagents of ACS grade, reagent grade, and pharmacopeia grade, as well as reagents graded for specific applications such as biosynthesis, chromatography and titration.
  • Reference Materials
    Reference Materials
    Controls used to validate measurements and calibrate assays.
  • Salts
    Ionic compounds formed by the neutralization of an acid and base. Salts are electrically neutral.
  • Solvents
    General use substances that dissolve solutes. Solvents can be polar or non-polar.
  • Sorbents
    Products that absorb or adsorb other materials.
  • Titration
    Products that determine the concentration of an analyte through the measured addition of a standard solution of known concentration.
