Buffer-related Reagents

Buffer-related Reagents — gathers hydroxylated amine compounds and organic acids used as buffer solution components or pH reference materials in various analytical systems. This group includes Tris base and its salts and derivatives, as well as organic acids such as tartrate and phthalate that are commonly used as standards.

Buffer-related Reagents are used in biochemistry and molecular biology laboratories to prepare buffer systems for protein/nucleic acid electrophoresis, cell culture, and enzymatic reactions that require controlled pH within a specific range. Compounds such as potassium hydrogen phthalate and tartaric acid also serve as primary standard materials for pH meter calibration, while Tris derivatives are widely used in preparing Tris-HCl or Tris-acetate buffers in molecular biology protocols.

Example products in this collection: TCI T3294 6850-28-8 Tris(hydroxymethyl)aminomethane Acetate, TCI C1562 102601-34-3 3-Cyclohexylamino-2-hydroxypropanesulfonic Acid Sodium Salt, TCI T2516 77-86-1 Tris(hydroxymethyl)aminomethane [for Electrophoresis], TCI C2426 73463-39-5 3-(Cyclohexylamino)-2-hydroxypropane-1-sulfonic Acid, TCI B1057 64431-96-5 1,3-Bis[tris(hydroxymethyl)methylamino]propane [for Buffer Material], TCI G0124 556-50-3 Glycylglycine, TCI T0740 1185-53-1 Tris(hydroxymethyl)aminomethane Hydrochloride, TCI I0288 288-32-4 Imidazole [for Buffer].

Pay attention to the purity grade suitable for analytical calibration ('for Buffer Material' or 'for Electrophoresis') as well as the salt or free base form, since both affect the pKa range and buffering capacity of the resulting solution. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
