LabChem® Ethanol-Benzene Mixture, 1:2, 4L

LabChem® ETHANOL-BENZENE MIXTURE, 1:2 is a pre-mixed solvent blend combining ethanol and benzene in a fixed 1:2 ratio, historically used as a standard extraction solvent for determining the total extractive content of wood, pulp, and fiber samples. Blending these solvents in a defined proportion provides a consistent extraction medium without the need to measure and combine them individually on the bench. Its pre-mixed formulation reduces preparation time and variability between batches.

It is commonly used as the extraction solvent in Soxhlet extraction procedures for determining resin, wax, and other extractive content in pulp, paper, and fiber testing. Using a consistently pre-mixed solvent helps ensure reproducible extraction results across testing sessions. This reagent should be handled, stored, and used according to established laboratory safety procedures and the manufacturer's instructions.
