Product Name – n-Pentane, 99+%, Extra Dry over Molecular Sieve, AcroSeal® Quantity/Pack Size – 1LT, 100ML Form – Liquid Grade – Extra Dry (99%+) Application – Solvent, extraction, chromatography
Product Overview
n-Pentane (99%+ purity) is a high-grade aliphatic hydrocarbon solvent processed with molecular sieves to achieve ultra-low moisture content, making it ideal for moisture-sensitive applications. The AcroSeal® packaging system ensures long-term stability by preventing atmospheric contamination, while the extra-dry formulation minimizes water interference in critical processes. This solvent boasts a narrow boiling range (36°C) for precise evaporation control, coupled with low viscosity and excellent solubility for nonpolar compounds. Its high volatility and low surface tension enable rapid sample penetration, while the absence of stabilizers guarantees minimal residue. The molecular sieve drying process removes trace water to <10 ppm, ensuring reproducibility in analytical and preparative workflows. Compatible with most organic solvents, this extra-dry grade eliminates the need for additional drying steps, saving time and reducing sample loss. The AcroSeal® cap features a PTFE-lined septum for repeated puncture without compromising seal integrity, making it suitable for automated systems.
FAQs
1. What makes this n-Pentane “extra dry” compared to standard grades?
This grade undergoes molecular sieve treatment to reduce water content below 10 ppm, unlike standard grades which may contain 50-100 ppm moisture. The drying process occurs under nitrogen atmosphere to prevent reabsorption.
2. Can this be used directly in GC-MS without further purification?
Yes, the 99%+ purity and extra-dry specification make it suitable for direct injection in GC-MS applications, though we recommend running a blank to verify baseline stability with your specific instrument.
3. How does the AcroSeal® packaging differ from regular bottles?
The AcroSeal® system combines a PTFE-lined septum with a screw cap, allowing needle penetration while maintaining a vapor-tight seal. This design prevents solvent evaporation and moisture ingress between uses.
4. What’s the typical shelf life when stored unopened?
Unopened bottles maintain specifications for 24 months from date of manufacture when stored at 15-25°C. The molecular sieve drying extends stability compared to non-dried solvents.
5. Are there any known incompatibilities with common lab materials?
n-Pentane will dissolve most plastics including polystyrene and polyethylene. Use only with PTFE, glass, or stainless steel components. Avoid contact with strong oxidizers like concentrated nitric acid.
