💎
99.99 % content (Ph. Eur.)
Documented purity grade in line with the European Pharmacopoeia – the strictest pharmaceutical purity class for substances.
🧪
Carrier & general solvent
Laboratory chemical and general solvent. During freezing it prevents the formation of ice crystals in the frozen material.
🌿
Vegan & REACH-registered
Free from materials of animal origin. Made in France. Registered under Regulation (EC) 1907/2006.
💧
250 ml brown glass + pipette
Light-protective amber glass in classic apothecary style. The enclosed plastic pipette enables drop-precise withdrawal.
Anyone ordering DMSO usually has a clear idea of the substance and a single question on their mind: does the stated purity actually hold up? In laboratory and research settings the gap between "technical" and "pharmaceutical-grade" matters enormously. That is exactly what this fill is built for.
Dimethyl sulfoxide (CAS 67-68-5) is a colourless, hygroscopic, polar aprotic solvent with a molar mass of 78.13 g/mol and a density of 1.104 g/cm³ at 20 °C. It is fully miscible with water. The documented content is 99.99 % – verified according to the requirements of the European Pharmacopoeia. One well-known physical quirk: the melting point sits at around 18 °C. Drop the room temperature below that and the liquid will crystallise. That is not a defect – just physics.
Behind every bottle sits a full technical dossier: a certificate of analysis to Ph. Eur. 8.0, a safety data sheet under Regulation (EC) 1907/2006 and a REACH registration. All starting materials are of non-animal origin.

📋 Handling notes
DMSO serves as a carrier substance, a so-called transport mediator and a general solvent. During freezing processes it prevents the formation of ice crystals in the frozen material.

What does "pharmaceutical-grade to Ph. Eur." actually mean?
The European Pharmacopoeia (Ph. Eur.) sets binding purity standards for pharmaceutically used substances – not only the minimum purity itself, but also the permitted ceilings for accompanying substances, water content and identification markers. A substance labelled "Ph. Eur." meets these requirements in full. For DMSO that corresponds to a documented content of at least 99.9 %, a water content below 0.2 % and related substances below 0.1 %.
Which pack sizes are available?
This variant is the 250 ml brown-glass bottle with pipette. Larger volumes of the same pharmaceutical quality are also available in 500 ml and 1000 ml.
⚠️ Pharmaceutical-grade (Ph. Eur.): Please note that handling chemicals always requires care and caution. DMSO freezes at temperatures below 18 °C. This is not a defect, but a physical property. Always store in warm conditions and re-liquefy crystallised material by gentle warming. Keep out of reach of children.
📦 Storage: Store upright. At low temperatures DMSO can crystallise – the ideal storage range is approximately 20–22 °C. Protect from light.
💬 Frequently asked questions
-
Why has my DMSO crystallised?+
The melting point of dimethyl sulfoxide sits at around 18 °C. When the ambient temperature drops below that figure, crystals form. This is not a quality issue – it is simply a property of the material. Gentle warming in a water bath at around 25–30 °C liquefies the substance again without affecting its purity.
-
What does "Ph. Eur." on the label mean?+
"Ph. Eur." stands for "Pharmacopoea Europaea" – the European Pharmacopoeia. This reference work defines the quality and purity requirements for substances used pharmaceutically across the EU member states. A material in Ph. Eur. quality meets strict analytical specifications for identity, content and admissible impurities.
-
Is this DMSO vegan?+
DMSO is produced synthetically. In the current certificate of analysis the manufacturer guarantees that the starting materials used are of non-animal origin.
-
Why is the bottle made of brown glass?+
Amber glass filters out short-wavelength light. It is the classic apothecary container for light-sensitive substances and helps preserve the material's original purity over longer periods.
-
What is included in the delivery?+
A sealed 250 ml brown-glass bottle of DMSO plus a plastic pipette for drop-precise withdrawal. The pipette is supplied separately within the packaging.
-
How should DMSO be stored?+
Upright, protected from light, at room temperature between roughly 20 and 22 °C. Cooler conditions will cause the liquid to solidify, but no harm is done. Keep out of reach of children.
