The full litre — pharmaceutical-grade purity at working scale
DMSO Dimethyl Sulfoxide in pharmaceutical-grade purity (Ph. Eur. 8.0) — a full litre in light-protective brown glass, for anyone working with DMSO regularly and wanting a consistent batch in stock.
💎
99.99 % content (Ph. Eur.)
Identical specification to the smaller fills — documented for every batch in line with the European Pharmacopoeia.
🧪
Universal solvent
Manufacturer-declared uses: laboratory chemical, chemical analytics, solvent and carrier substance. Prevents the formation of ice crystals in frozen material.
🌿
Vegan & REACH-registered
Of non-animal origin. REACH registration under Regulation (EC) 1907/2006, country of origin France.
💧
1 litre brown glass + pipette
A full litre in amber apothecary glass — light and moisture protection built in. Plastic pipette for clean sampling supplied.
Anyone ordering a litre of DMSO typically isn't handling the material for the first time. The question is no longer "is this really pharmaceutical-grade?" but "will the specification and the batch stay constant across my entire usage period?" The litre pack answers that most clearly: one bottle, one certificate of analysis, one continuous supply.
Chemically nothing changes compared with the smaller fills. Dimethyl sulfoxide (CAS 67-68-5) with a molar mass of 78.13 g/mol, a density of 1.104 g/cm³ at 20 °C and a documented content of 99.99 % to Ph. Eur. 8.0. The melting point of around 18 °C brings only one practical implication at the litre scale: re-liquefying crystallised material takes longer than with smaller bottles — a tempered water bath and a little patience are the only tools needed.
The technical documentation matches the smaller fills entirely: certificate of analysis to Ph. Eur. 8.0, safety data sheet under Regulation (EC) 1907/2006, REACH registration and confirmation of non-animal starting materials. If you would like to explore further options from the Viterna range, you may also wish to take a look at Vital Eyebright Drops 100 ml and the Vital Artemisia DMSO Tincture (alcohol-free) 100 ml.

📋 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 should you keep in mind when handling a litre bottle?
DMSO has a density of 1.104 g/cm³ — a litre therefore weighs around 1.1 kg. The filled bottle should be lifted with both hands, ideally with the thumb under the base and the fingers around the neck. Because the substance is hygroscopic, it makes sense to reseal the bottle promptly after each withdrawal. Crystallised material is liquefied exclusively in a water bath (around 25–30 °C) — never in the microwave.
Which pack sizes are available?
This variant is the litre bottle in brown glass. For smaller demand, 250 ml and 500 ml are available in the same pharmaceutical quality.
⚠️ 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
-
How long does it take to re-liquefy a crystallised litre bottle?+
That depends on the water-bath temperature and the ambient temperature. With a bath at around 25–30 °C and room-temperature surroundings, full liquefaction of a litre bottle can take significantly longer than for the smaller fills — depending on conditions, several hours. Important: never heat in the microwave and do not exceed 40 °C.
-
What should I watch out for when handling the 1-litre bottle?+
A filled litre weighs around 1.1 kg. A stable, tip-proof surface for storage is important. Because DMSO absorbs moisture from ambient air, the bottle should be resealed promptly after each withdrawal. For frequent withdrawals in routine work, it makes sense to decant smaller working volumes — that way the main bottle stays closed more often.
-
Does the material come from a single batch?+
Yes. Each litre bottle is filled from a specific batch — the batch identifier is given on the label as a lot number. The corresponding certificate of analysis documents the specification of that batch to Ph. Eur. 8.0. Anyone wanting to work with consistent specification over a longer demand period gets the maximum possible batch consistency with the litre pack.
-
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 glass and not HDPE?+
Amber glass is inert to light exposure and chemically particularly neutral towards polar aprotic solvents. For storing pharmaceutical-grade substances it is the classic choice. HDPE bottles are an alternative for other application areas — this range uses apothecary glass.
-
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.
