Solvants

Solvants

Les solvants sont des liquides, solides ou gaz qui ont la capacité de dissoudre d'autres substances, formant une solution sans changer la nature chimique des substances dissoutes. Ils sont fondamentaux dans une variété d'applications, allant du nettoyage et de l'extraction à la formulation de produits chimiques et pharmaceutiques, ainsi que dans la fabrication de peintures, encres et adhésifs. Chez CymitQuimica, nous proposons une large gamme de solvants de haute pureté et qualité, adaptés à diverses applications scientifiques et industrielles. Notre catalogue comprend des solvants organiques et inorganiques, ainsi que des solvants spécialisés pour des applications spécifiques en recherche, développement et production à grande échelle.
