Product Overview
Propan-2-ol (isopropyl alcohol) EL grade is a high-purity, extra-low residue solvent designed for critical laboratory applications. With a minimum purity of 99.9%, this reagent-grade alcohol ensures minimal interference in sensitive procedures, making it indispensable for molecular biology, analytical chemistry, and general lab maintenance. The EL grade designation guarantees ultra-low levels of contaminants like aldehydes, ketones, and non-volatile residues, which is crucial for applications requiring high solvent evaporation without residue formation. This isopropyl alcohol variant exhibits excellent miscibility with water and most organic solvents, offering a balanced polarity that enhances its versatility. Its rapid evaporation rate (leaving no streaks or residues) makes it particularly valuable for cleaning glassware, electronic components, and precision instruments. The solvent’s low UV absorbance (cutoff at 210 nm) further extends its utility in HPLC, spectroscopy, and other optical applications where solvent transparency is paramount. Packaged in high-density polyethylene containers to prevent contamination and solvent loss, this product maintains its integrity during storage and transport. The 2.5-liter packaging provides an optimal balance between bulk efficiency and laboratory practicality, reducing the need for frequent reordering while maintaining freshness. Each batch undergoes rigorous quality control testing, including GC-MS analysis, to verify purity and absence of DNase/RNase, ensuring reliability for even the most demanding protocols.
FAQs
1. What is the difference between EL grade and regular isopropyl alcohol?
EL grade isopropyl alcohol undergoes additional purification steps to remove trace contaminants like aldehydes and non-volatile residues that are present in regular grades. This makes it suitable for sensitive applications where residue could interfere with results, such as molecular biology and analytical chemistry.
2. Can this isopropyl alcohol be used for DNA/RNA extraction?
Yes, the EL grade is specifically designed for nucleic acid precipitation and extraction protocols. Its ultra-low residue profile prevents contamination that could inhibit downstream applications like PCR or sequencing.
3. What is the typical shelf life of this product when stored properly?
When stored in its original, tightly sealed container at room temperature (15-25°C) away from direct sunlight and moisture, this isopropyl alcohol maintains its specified purity for at least 24 months from the date of manufacture.
4. Is this product compatible with plastic labware?
While isopropyl alcohol is generally safe for most common lab plastics like PP and HDPE, prolonged exposure may affect some polymers. For critical applications, we recommend testing compatibility with your specific plasticware or using glass containers where possible.
5. What alternatives exist if I need a higher water content in my solvent?
For applications requiring aqueous isopropyl alcohol solutions, you can prepare dilutions using ultrapure water (18.2 MΩ·cm). Common concentrations like 70% v/v are typically prepared by mixing 700 mL of this absolute alcohol with 300 mL of ultrapure water.
