Product Name – Methyl sulfoxide, 99.7+%, Extra Dry over Molecular Sieve, AcroSeal® Quantity/Pack Size – 100ML, 500ML, 1LT, 2.5LT Form – Liquid Grade – Extra Dry (99.7%+) Application – Solvent, cryopreservation, sample dissolution
Product Overview
Methyl sulfoxide (DMSO) at 99.7%+ purity represents the gold standard for anhydrous solvent applications in laboratory settings. This extra-dry grade undergoes rigorous molecular sieve treatment to eliminate residual moisture, ensuring unparalleled stability and performance in moisture-sensitive protocols. The AcroSeal® packaging system provides an additional layer of protection against atmospheric contamination, maintaining the solvent’s integrity from production to use. Characterized by its exceptional solvency power, this DMSO variant demonstrates superior compatibility with both polar and nonpolar compounds, making it indispensable for complex sample preparations. The ultra-low water content (<0.01%) prevents unwanted side reactions in sensitive applications while preserving the solvent's characteristic properties: high boiling point (189°C), low toxicity profile, and remarkable tissue penetration capabilities. Each batch undergoes stringent quality control measures to verify the absence of impurities that could compromise experimental outcomes. The solvent's optical clarity and consistent refractive index further enhance its utility in spectroscopic applications.
FAQs
1. What distinguishes extra-dry DMSO from standard laboratory-grade DMSO?
Extra-dry DMSO undergoes additional purification through molecular sieves to achieve water content below 0.01%, compared to standard grades which typically contain 0.1-0.5% water. This makes it suitable for moisture-sensitive reactions.
2. How does AcroSeal® packaging benefit DMSO storage?
The AcroSeal® system creates a hermetic barrier that prevents moisture ingress and atmospheric contamination during storage, significantly extending the solvent’s shelf life and maintaining its anhydrous properties.
3. Can this DMSO be used for cryopreservation applications?
Yes, the high purity and low water content make it particularly effective for cryopreservation protocols where cellular viability depends on minimizing ice crystal formation.
4. What’s the typical shelf life of unopened extra-dry DMSO?
When stored properly in its original AcroSeal® packaging at room temperature, unopened extra-dry DMSO maintains its specifications for at least 24 months from the date of manufacture.
5. Are there any special handling requirements for this grade of DMSO?
While handling requirements remain similar to standard DMSO, the extra-dry nature demands particular attention to preventing moisture exposure during use. Always work in a dry environment and reseal containers immediately after use.
