The choice of the exact solvent often decides the success or failure of an analysis in the laboratory. Dimethyl sulfoxide (DMSO) dissolves both polar and nonpolar compounds precisely and residue-free. Discover the technical parameters of our high-purity DMSO (99.9%) and learn how to safely use this indispensable substance in synthesis, analytics, or as a cryoprotectant.

Technical Specification and Identification

Reproducible laboratory results require chemicals of uncompromising quality. Our dimethyl sulfoxide, BIOLABORATORIUM, provides you with precisely this reliable basis for your processes.

Professional Application Areas in the Laboratory

The high dielectric constant makes DMSO one of the strongest organic solvents. Professionals use it across industries:

• Chemical Industry & Synthesis: It acts as a highly efficient reaction medium. The structure massively accelerates complex organic and inorganic synthesis processes, such as nucleophilic substitutions.
• Biotechnology & Cell Research: DMSO is the gold standard among cryoprotectants. Researchers add it to cell cultures and sensitive tissue samples to prevent the destructive formation of ice crystals during storage at low temperatures, i.e., cryopreservation.
• Analytical Chemistry: Laboratory technicians use the reagent in demanding chromatographic analyses that require the complete dissolution of poorly soluble compounds.
• Materials Research: Engineers test the chemical resistance of innovative polymers with pure DMSO.

Strict Safety and Storage Guidelines

DMSO has strong hygroscopic properties – it continuously absorbs moisture from the ambient air. In addition, the pure liquid already solidifies at about 18 °C.

Secure the integrity of the reagent through these storage conditions:

• Store the product exclusively in tightly sealed original containers.
• Choose a cool, dry, and well-ventilated storage location, protected from direct sunlight.
• Keep the solvent strictly away from heat sources, open flames, and strong oxidizing agents.
• Secure the room against unauthorized access.

Secure a solvent that meets the highest technical requirements.
