n-Heptan

n-Heptane (C₇H₁₆) is a straight-chain aliphatic hydrocarbon with a boiling point of 98 °C, low polarity, and high volatility. It serves as a standard reference fuel for octane rating determination and as a nonpolar solvent in analytical chemistry and industrial cleaning. n-Heptane is also employed in the formulation of adhesives, coatings, and polymer processing. Due to its rapid evaporation rate and flammability, it should be handled in well-ventilated areas and stored in tightly closed containers away from ignition sources.

n-Heptan, Uvasol® für die Spektroskopie, Supelco®

Supplier: Merck

Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol® solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol® solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph Eur and ACS.

n-Heptan, LiChrosolv® für die Flüssigchromatographie, Supelco®

Supplier: Merck

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.
