Description
Disperse blue 183 is an organic colorant reagent supplied for laboratory chemical and biochemical applications. It is registered under CAS number 2309-94-6, with the empirical formula C₂₀H₂₁BrN₆O₃ and a molar mass of 473,32 g/mol. This listing provides, giving sufficient material for dyeing trials, analytical comparison, formulation screening, and educational or industrial laboratory work that requires a defined disperse blue dye. Physical identity is anchored by the stated molecular formula and molar mass, enabling accurate stoichiometric calculation and documentation in research notebooks and quality records. The product is offered from manufacturer Carl ROTH within its chemicals portfolio. Disperse dyes of this class are commonly employed when laboratories need reproducible coloration behaviour on hydrophobic substrates or when reference samples are prepared for spectroscopic and chromatographic methods. Consistent CAS and formula data support inventory control, safety assessment, and cross-site transfer of methods where the same dye identity must be maintained.
This article is part of Homogenisers & dispersers, in Stirring, shaking & mixing.

Questions about Disperse blue 183, 250 g
What is this article?
Disperse blue 183, 250 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.
