Description
Disperse Orange 3 is an organic disperse dye with CAS number 730-40-5 and empirical formula C₁₂H₁₀N₄O₂. It has a molar mass of 242,23 g/mol, enabling accurate calculation of molar amounts for solution work and experimental design. size is convenient for method development, small-scale dyeing trials, analytical characterisation and teaching or research laboratories that require a defined orange disperse colourant. Applications span textile chemistry, materials research and broader biochemical workflows in which a compact quantity of a well-specified dye is preferred. Identity data—CAS number, formula and molar mass—support documentation, cross-referencing with published methods and consistent preparation of stocks or standards. The product is available from manufacturer Carl ROTH in its chemicals and biochemicals portfolio. Clear unit quantity and molecular parameters help maintain traceability from receipt through laboratory use. Select

Questions about Disperse Orange 3, 50 g
What is this article?
Disperse Orange 3, 50 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Homogenisers & dispersers, inside Stirring, shaking & mixing, in Lab instruments.
A homogeniser or disperser uses a rotor inside a stator to tear a sample and disperse it. Tip diameter and speed decide the particle size. A generator for 2 mL and a generator for 1 L are different tools on, sometimes, the same drive.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
