Product Overview
n-Heptane, 99%+ Extra Dry, is a high-purity aliphatic hydrocarbon solvent designed for critical laboratory applications. This ultra-refined grade ensures minimal moisture content (Extra Dry), making it ideal for sensitive processes where water interference must be avoided. Its narrow boiling range and consistent composition provide reliable performance in solvent extraction, thin-layer chromatography (TLC), and gas chromatography (GC). The AcroSeal® packaging guarantees long-term stability and protection against contamination, preserving the solvent’s integrity. With a purity level exceeding 99%, this n-Heptane variant is free from impurities that could compromise experimental accuracy. Its low UV absorbance and high volatility further enhance its suitability for spectroscopic and analytical techniques. Whether used as a reference standard or a reaction medium, this solvent delivers precision and reproducibility, meeting the stringent demands of modern laboratories.
FAQs
1. What is the difference between Extra Dry and standard n-Heptane?
Extra Dry n-Heptane undergoes additional drying processes to reduce moisture content to trace levels, making it suitable for moisture-sensitive applications where standard grades may introduce water-related errors.
2. Can this n-Heptane be used in HPLC applications?
While n-Heptane is not a common mobile phase in HPLC, its high purity makes it compatible as a secondary solvent or for sample preparation, provided the system is optimized for its viscosity and UV transparency.
3. How should Extra Dry n-Heptane be stored to maintain its purity?
Store the sealed container in a cool, dry place away from direct sunlight and ignition sources. Once opened, use under inert gas (e.g., nitrogen) to prevent moisture absorption and oxidation.
4. Is this n-Heptane compatible with plastic labware?
n-Heptane can dissolve or swell certain plastics like polystyrene or polyethylene. Use glass or PTFE-coated containers to avoid contamination or container degradation.
5. What alternatives exist if n-Heptane is unavailable?
For similar applications, cyclohexane or iso-octane may serve as alternatives, though their polarity and boiling points differ. Always verify compatibility with your specific protocol.
