Application and notes

This product is intended for the analysis of pesticide residues by gas chromatography (GC). Due to its high purity and minimal evaporation residues, this cyclohexane provides reliable results for analytical laboratories involved in quality control of food, environmental, and toxicological studies. Storage in a cool, dry, and well-ventilated area in closed, solvent-resistant containers is recommended.
