Product Name – Ethanol, absolute, ≥99.8%, ACS reagent Quantity/Pack Size – 500mL, 2.5L, 1L Form – Liquid Grade – ACS reagent, absolute Application – Solvent extraction, chromatography, molecular biology
Product Overview
This ACS reagent grade absolute ethanol delivers ≥99.8% purity with exceptionally low water content (<0.1%), meeting stringent requirements for anhydrous applications. The colorless liquid undergoes molecular sieve drying to achieve ultra-low moisture levels critical for sensitive procedures. Each batch undergoes comprehensive testing for aldehydes, ketones, and other organic impurities that could interfere with analytical results. The stabilized formulation resists water absorption during storage while maintaining consistent volatility characteristics. Its high purity ensures complete miscibility with most organic solvents without introducing contaminants. The ethanol's low UV absorbance makes it suitable for spectroscopic applications where optical clarity is essential. Packaged in amber glass bottles with PTFE-lined caps to prevent evaporation and contamination, the product meets Indian safety standards for flammable liquids. The absolute grade eliminates the need for additional drying steps in most applications, saving time and reducing potential sample loss. Its controlled peroxide content (<2 ppm) prevents oxidation of sensitive compounds during storage and use.
FAQs
1. What’s the typical water content in this ethanol?
The water content is ≤0.1% by weight, with most batches testing below 0.05% as verified by Karl Fischer titration.
2. Can this be used for DNA precipitation?
Yes, the ultra-low water content and high purity make it ideal for molecular biology applications including DNA/RNA precipitation.
3. How should this be stored to maintain anhydrous conditions?
Store in original containers with tight seals, preferably under nitrogen if long-term storage is required to prevent moisture absorption.
4. What’s the difference between this and 95% ethanol?
This absolute grade contains ≤0.1% water versus ~5% in 95% ethanol, with significantly lower impurities for critical applications.
5. Is this suitable for HPLC applications?
Yes, the high purity and low UV absorbance make it excellent for HPLC mobile phases and sample preparation.
