Product Name – n-HEPTANE 95% PRA Quantity/Pack Size – 1000 ml Form – Liquid Grade – PRA (Pro Analysis) Application – Solvent for chromatography, extractions, and standard calibration
Product Overview
n-Heptane 95% PRA is a high-purity, non-polar solvent widely used in laboratory settings for its consistent performance and reliability. This aliphatic hydrocarbon, with a boiling point of approximately 98°C, is a key component in gas chromatography, serving as a reference standard for calibration due to its well-defined properties. Its low polarity makes it an excellent choice for extracting non-polar compounds, ensuring minimal interference in analytical procedures. The PRA (Pro Analysis) grade guarantees minimal impurities, making it suitable for sensitive applications where precision is critical. The solvent is also employed in fuel research and as a diluent in various chemical processes. Its stability under standard lab conditions ensures long shelf life without degradation, provided it is stored in a tightly sealed container away from heat and ignition sources. The 1000 ml pack size offers a practical volume for frequent use, reducing the need for repetitive ordering while maintaining freshness.
