FAQ – Dimethyl Sulfoxide (DMSO)
What is DMSO?
What is DMSO?
DMSO (dimethyl sulfoxide) is an organic solvent used primarily in laboratories, research, and certain technical applications. It is valued for its ability to dissolve many compounds and for its complete miscibility with water.
What is DMSO used for?
What is DMSO used for?
DMSO is mainly used in scientific and analytical contexts, particularly for dissolving substances, laboratory testing, and certain industrial technical applications. Its use must always comply with regulations and conditions stipulated for this type of substance.
Why choose DMSO ≥ 99.9%?
Why choose DMSO ≥ 99.9%?
High-purity DMSO ensures better stability, limits the presence of impurities, and leads to more reliable results in technical or analytical applications. Purity is an essential criterion for ensuring the reproducibility and quality of protocols.
How to store DMSO?
How to store DMSO?
To preserve its characteristics, DMSO must be stored:
- In a tightly sealed container
- At controlled room temperature (15-25 °C)
- Away from moisture and air
The product may naturally crystallize at temperatures around 18.5 °C. This phenomenon is normal and reversible: simply gently warm the bottle to liquefy it.
