AR Grade Ethanol


AR Grade Ethanol 

Overview
AR Grade Ethanol (Analytical Reagent Grade Ethanol) offered by Zenith Bio Chemical Industries Pvt. Ltd. is the highest purity ethanol specifically manufactured for use in laboratories, research institutes, analytical testing, and high-precision scientific processes. This ethanol grade adheres to strict quality norms ensuring minimal contaminants, maximum accuracy, and reliable performance in highly sensitive applications.

AR Grade Ethanol is widely used by professionals in analytical chemistry, life sciences, pharmaceuticals, environmental testing, and academic institutions where reagent purity directly affects test results and outcome credibility.

Product Composition and Purity

AR Grade Ethanol is refined to deliver ethanol purity of 99.9% or higher, with strict limits on impurities such as methanol, aldehydes, ketones, and heavy metals. The formulation ensures complete solubility and low residue, making it suitable for both qualitative and quantitative analysis.

  • Chemical Formula: C₂H₅OH

  • Purity: 99.9%+ (Analytical Reagent Grade)

  • Color: Clear, transparent

  • Odor: Slight characteristic odor

  • pH: Neutral

  • Residue after Evaporation: < 0.001%

  • UV Absorbance: Within prescribed range for spectroscopy work

Core Applications

  1. Analytical Chemistry
    AR Grade Ethanol is used as a solvent and diluent in HPLC (High-Performance Liquid Chromatography), spectrophotometry, and titration processes. Its purity ensures no background interference or false peaks in test results.

  2. Life Science Research
    Used in DNA/RNA extraction, protein purification, and cell culture work, where contaminant-free conditions are critical. Its non-cytotoxic properties allow safe usage in biological assays.

  3. Pharmaceutical Quality Control
    Employed in the preparation of standards, sample cleaning, and calibration processes. Since many pharmaceutical labs are subject to stringent regulatory inspections, the reliability of AR Grade Ethanol is a fundamental requirement.

  4. Environmental Testing and Water Analysis
    Acts as a solvent in the identification and quantification of organic pollutants, residues, and chemical markers in soil, water, and air samples.

  5. Spectroscopy and Chromatography
    AR Grade Ethanol is suitable for UV-VIS, IR, and NMR spectroscopy, offering ultra-low absorbance values that do not affect spectrophotometric readings.

  6. Tissue Preparation in Histopathology
    Used in dehydrating tissue samples, slide preparation, and cleaning of glassware in pathology labs. Its non-streaking and residue-free finish ensures microscopic clarity.
