Product Overview
Dimethyl sulfoxide (DMSO) reference standard is a high-purity solvent designed for precise analytical applications in laboratory settings. This HPLC-grade DMSO offers exceptional purity (99.9%) and consistency, making it an ideal choice for calibration in chromatography and other analytical techniques. Its low UV absorbance and minimal impurities ensure reliable results in sensitive analyses. The solvent is stable under standard lab conditions and compatible with a wide range of organic and inorganic compounds. Its hygroscopic nature requires proper sealing to maintain purity. This reference standard is particularly valued for its ability to dissolve both polar and nonpolar substances, enhancing its versatility in laboratory protocols. The 100 ml pack size provides sufficient volume for repeated use while maintaining freshness. Each batch undergoes rigorous quality control to ensure compliance with international standards, making it a trusted choice for researchers requiring accurate, reproducible results.
FAQs
1
What is the shelf life of this DMSO reference standard?
When stored properly in a tightly sealed container at room temperature, this DMSO reference standard maintains its stability for up to 24 months from the date of manufacture. 2
Is this DMSO suitable for NMR spectroscopy?
While primarily designed for HPLC applications, this high-purity DMSO can be used in NMR spectroscopy, though deuterated DMSO is typically preferred for proton NMR to avoid signal interference. 3
How should I store this reference standard to maintain purity?
Store the bottle upright in a cool, dry place away from direct sunlight. Always keep the cap tightly closed when not in use to prevent moisture absorption. 4
What makes this DMSO different from regular laboratory-grade DMSO?
This reference standard undergoes additional purification processes to achieve higher purity levels (99.9%) and stricter quality control, making it more suitable for analytical calibration compared to general laboratory-grade DMSO. 5
Can this DMSO be used as a cryopreservative?
While DMSO is commonly used in cryopreservation, this reference standard is specifically formulated for analytical applications and may not contain the necessary additives typically found in cryopreservation-grade DMSO.
