Important: Slightly contaminated <99% DMSO is often offered online - we demonstrably only use DMSO of the highest pharmaceutical purity, which means 99.9% and certified according to the European Pharmacopoeia.
DMSO becomes crystalline and solid at low temperatures below 18°C, e.g. during transport in winter. This behavior is typical for DMSO and completely harmless. It becomes liquid again when warmed up in a lukewarm water bath. Use within 12 months after opening. Store in a cool, dry place, upright, tightly closed and out of reach of children!
The DMSO 100 ml bottle is ideal for beginners. The 100 ml bottle is also very practical and handy when traveling. If you have a greater need, then choose our economical DMSO 250 ml bottle.
