Product Name – Methyl sulfoxide, 99.8+%, for HPLC Quantity/Pack Size – 1LT, 2.5LT Form – Liquid Grade – HPLC Application – Solvent for chromatography, sample dissolution, biochemical assays
Product Overview
Methyl sulfoxide (DMSO) of 99.8% purity is a high-performance HPLC-grade solvent designed for demanding laboratory applications requiring minimal impurities and consistent results. This ultra-pure DMSO exhibits exceptionally low UV absorbance, making it ideal for sensitive chromatographic separations where baseline stability is critical. Its hygroscopic nature ensures rapid dissolution of both polar and nonpolar compounds, while the stringent purification process eliminates residual contaminants that could interfere with analytical measurements. The solvent’s high boiling point (189°C) and thermal stability allow for reliable performance across a wide temperature range in instrumentation. Unlike technical-grade DMSO, this HPLC-specific formulation undergoes rigorous quality control to meet strict chromatographers’ requirements, including reduced particulate matter and metal ion content. The solvent’s aprotic properties make it particularly effective for dissolving proteins, nucleic acids, and other biomolecules without inducing structural changes. Packaged in amber glass bottles to prevent light-induced degradation, this DMSO maintains its purity throughout storage and handling. Its compatibility with most organic solvents and aqueous systems further enhances its versatility in complex sample preparation workflows.
FAQs
1. What makes this DMSO suitable for HPLC applications?
This DMSO undergoes additional purification steps to remove UV-absorbing impurities and particulate matter that could interfere with chromatographic detection. The 99.8% purity level ensures minimal baseline noise and consistent retention times in HPLC systems.
2. Can this DMSO be used for cell culture applications?
While this is primarily formulated for HPLC, its high purity makes it potentially suitable for some cell culture applications. However, we recommend using cell culture-grade DMSO specifically tested for endotoxin levels if working with sensitive cell lines.
3. How should this DMSO be stored to maintain its purity?
Store in the original amber glass container at room temperature, tightly sealed to prevent moisture absorption. Avoid prolonged exposure to light and keep away from strong oxidizing agents to preserve its chemical integrity.
4. What’s the difference between this HPLC-grade DMSO and regular laboratory-grade DMSO?
HPLC-grade DMSO has significantly lower levels of UV-absorbing impurities, metals, and particulate matter compared to regular laboratory-grade. It’s specifically purified to meet the requirements of high-performance liquid chromatography systems where even trace contaminants can affect results.
5. Is this DMSO compatible with plastic containers during use?
While DMSO can dissolve some plastics, this grade is generally safe for short-term contact with common laboratory plastics like polypropylene and PTFE. For long-term storage or sensitive applications, we recommend using glass containers to prevent potential leaching of plasticizers.
