FIVE STAR MATERIALS RESOURCES DMSO Liquid 99.95% Dimethyl Sulfoxide — 8 oz Sterile Glass Bottle with Dropper, Lab-Grade Solvent

FIVE STAR MATERIALS RESOURCES DMSO Liquid 99.95% is a laboratory-grade dimethyl sulfoxide solvent supplied in an 8 oz sterile glass bottle with a dropper for precise handling.

This product is a high-purity DMSO solution formulated for laboratory and industrial applications where a low-odor, reliable solvent or cryoprotectant is required. Packaged in a sterile glass bottle and purified to 99.95%, this DMSO is intended strictly for research, industrial, or laboratory use. The formulation may crystallize at cooler temperatures; that physical change signals purity rather than contamination and can be reversed by warming gently in water.

How should I store and handle this DMSO to keep it stable?

Store the bottle tightly sealed in a cool, dry place away from direct sunlight and ignition sources. Avoid exposure to extreme heat; refrigeration is unnecessary but keep above its crystallization point if you want it to remain liquid.

• Keep tightly capped in original glass container to prevent contamination.
• Store at ambient lab temperatures above 64°F to avoid crystallization.
• Use appropriate PPE—gloves and eye protection—when dispensing.
• Do not heat in a microwave or expose to open flame; warm only in a water bath if needed.

What do I do if the DMSO has crystallized on arrival?

Crystallization indicates a high level of purity and is reversible. To return the product to liquid, place the sealed glass bottle in warm (not boiling) water and allow it to equilibrate gradually until fully dissolved.

• Place sealed bottle in a warm water bath for several hours to dissolve crystals.
• Do not use boiling water or microwave heating—use gentle, indirect warmth only.
• Inspect the seal before warming to ensure container integrity.
• If cloudiness persists, contact the supplier with lot information for guidance.

What applications is this DMSO suitable for in a lab or industrial setting?

This DMSO is formulated as a general-purpose solvent and cryoprotectant useful across multiple workflows. It is appropriate for solvent systems, reagent preparation, and other industrial or laboratory tasks that require a high-purity polar aprotic solvent.

• Use as a solvent in chemical reactions and formulations requiring polar aprotic media.
• Suitable as a cryoprotectant component in controlled laboratory protocols.
• Applicable for intermediate processing steps in industrial manufacturing.
• Intended only for non-consumable, non-medical, and non-cosmetic uses as specified.

What safety precautions and disposal recommendations should I follow?

Handle DMSO with standard laboratory safety practices: avoid skin contact, use gloves and eye protection, and work in a well-ventilated area. Dispose of unused material and empty containers according to local hazardous-waste regulations to minimize environmental impact.

• Wear nitrile gloves and safety goggles when handling the product.
• Work in a fume hood or ventilated space to reduce vapor exposure.
• Segregate DMSO waste and follow institutional hazardous-waste protocols.
• Do not apply to skin or use for medical/therapeutic purposes; product is sold as a chemical solvent.

Who this product is for: This 8 oz glass bottle of FIVE STAR MATERIALS RESOURCES DMSO 99.95% is designed for laboratory technicians, research scientists, and industrial formulators who require a high-purity, low-odor polar solvent supplied in a sterile glass container for precise dosing. It is not intended for human or veterinary medical use, cosmetic applications, or ingestion. If your work demands trace-level purity, reliable packaging, and clear handling guidance, this DMSO meets those criteria while emphasizing appropriate safety and disposal procedures.
