Product Name – Methyl sulfoxide, 99.7+%, Extra Dry, AcroSeal® Quantity/Pack Size – 100ML, 1LT, 2.5LT Form – Liquid Grade – Extra Dry, 99.7+% Application – Solvent, cryopreservation, chemical reactions
Product Overview
Methyl sulfoxide (DMSO), 99.7% purity in Extra Dry grade, is a versatile polar aprotic solvent renowned for its exceptional solvency power and low toxicity. This high-grade DMSO is meticulously purified to eliminate water content, making it ideal for moisture-sensitive applications where trace impurities could compromise results. The AcroSeal® packaging ensures long-term stability by minimizing exposure to atmospheric moisture and contaminants, preserving the solvent’s integrity until use. With a boiling point of 189°C and miscibility in both polar and nonpolar solvents, this DMSO variant serves as an excellent medium for dissolving a wide range of organic and inorganic compounds. Its hygroscopic nature demands careful handling, while its ability to penetrate biological membranes makes it valuable in cryopreservation protocols. The Extra Dry specification guarantees water content below 50 ppm, critical for applications like lithium battery electrolyte preparation or air-sensitive organometallic reactions. This product maintains consistent performance across batch variations, supported by rigorous quality control measures to ensure reproducibility in experimental setups.
FAQs
1. What does “Extra Dry” mean in this DMSO specification?
The Extra Dry designation indicates this DMSO has undergone additional purification to reduce water content to less than 50 ppm, making it suitable for moisture-sensitive applications where standard grades might introduce unwanted water.
2. How does AcroSeal® packaging benefit this product?
AcroSeal® packaging uses a specialized septum cap system that prevents moisture ingress and contamination, maintaining the solvent’s purity during storage and between uses, which is particularly important for hygroscopic solvents like DMSO.
3. Can this DMSO be used for cryopreservation applications?
Yes, the high purity and low water content make this DMSO particularly effective for cryopreservation, where water content can affect cell viability during freezing and thawing processes.
4. What precautions should be taken when handling this solvent?
DMSO readily penetrates skin and can carry dissolved substances with it, so proper PPE including nitrile gloves and safety goggles should be used. It should be handled in a well-ventilated area or fume hood.
5. How should this product be stored for optimal shelf life?
Store in a cool, dry place with the original AcroSeal® cap tightly sealed. Keep away from oxidizing agents and sources of ignition, as DMSO is combustible at elevated temperatures.
