Product Overview
Cyclohexane ARS, ACS is a high-purity, non-polar solvent widely used in laboratory applications where precision and consistency are critical. This cycloaliphatic hydrocarbon is distilled to meet ARS (Analytical Reagent Grade) and ACS (American Chemical Society) standards, ensuring a minimum purity of 99.5% with negligible impurities like water, sulfur compounds, or residual solvents. Its low reactivity and excellent solvency power make it ideal for dissolving non-polar compounds, while its narrow boiling range (80.7°C) ensures reproducible results in distillation and extraction processes. The solvent is stabilized to prevent peroxide formation, extending shelf life without compromising performance. Packaged in high-density polyethylene (HDPE) containers, it resists chemical degradation and contamination, maintaining integrity during storage and transport. Cyclohexane’s refractive index (1.426) and density (0.779 g/mL) are tightly controlled, providing reliable baseline data for analytical procedures. Compatible with most glassware and PTFE-sealed systems, it minimizes leaching or adsorption issues. For laboratories requiring traceable, batch-certified solvents, this product includes a Certificate of Analysis (CoA) with GC/MS validation, ensuring compliance with ISO and GLP standards.
FAQs
1. What is the difference between ARS and ACS grades in Cyclohexane?
ARS (Analytical Reagent Grade) and ACS (American Chemical Society) grades both indicate high purity, but ACS follows stricter specifications set by the ACS committee. ARS is often equivalent but may have slight variations in impurity limits depending on the manufacturer. This product meets both standards.
2. Can this Cyclohexane be used with plastic labware?
While Cyclohexane is generally compatible with HDPE and PTFE, prolonged exposure may cause swelling or degradation in some plastics like polystyrene or PVC. Always use glass or chemically resistant containers for long-term storage or reactions.
3. How should I store Cyclohexane to prevent contamination?
Store in a tightly sealed, original HDPE container away from direct sunlight, heat sources, and oxidizing agents. Keep the container in a well-ventilated, flammable-liquid storage cabinet at temperatures below 25°C to minimize evaporation and peroxide formation.
4. Is this Cyclohexane stabilized against peroxide formation?
Yes, this product includes a stabilizer (typically BHT or similar) to inhibit peroxide formation during storage. However, always test for peroxides before use if stored for over 12 months, especially after opening.
5. What alternatives can replace Cyclohexane in chromatography?
For non-polar solvent applications, n-hexane or heptane are common alternatives, though their selectivity and boiling points differ. Hexane is more volatile, while heptane offers slightly higher polarity. Always validate substitutes with your specific method.
