Ethanol-Benzene Mixture, 1:2

Features:

• Comprehensive Extraction: Unlike single solvents, this mixture provides the most complete removal of residual solvent-extractable substances in pulp, including waxes, fats, resins, and low-molecular-weight carbohydrates.
• Pre-Mixed Precision: Eliminates the significant health risks and measurement errors associated with manually mixing high volumes of toxic benzene and ethanol in the laboratory.
• Regulatory Compliance: Essential for laboratories performing Klason lignin determination (TAPPI T 222) where pre-extraction of resins is a mandatory step.
• NIST-Traceable Quality: Manufactured under LabChem’s rigorous quality standards to ensure consistent extractive yields across different batches.

Safety & Regulatory Information:

DANGER Highly Toxic & Carcinogenic: This product contains Benzene, a confirmed human carcinogen, and Ethanol (often denatured with Methanol).

• California Prop 65: WARNING: This product can expose you to chemicals including Benzene, which is known to the State of California to cause cancer and birth defects or other reproductive harm.
• Handling: Must be used in a high-efficiency chemical fume hood. Wear specialized personal protective equipment (PPE), including silver shield or Viton gloves, as standard nitrile may not provide an adequate breakthrough time for benzene.
• Shipping Restrictions: This is a DOT-regulated hazardous material (UN1993, Flammable Liquid, n.o.s.). It only ships to registered research laboratories or commercial facilities. No residential delivery.
