Ethanol absolute for analysis (EMSURE ACS, ISO, Reag. Ph Eur) is a premium, high-purity solvent used for critical analytical applications, pharmaceutical testing, and sophisticated organic synthesis requiring near-zero water content.
Ethanol absolute, also known as undenatured ethyl alcohol, is a clear, colorless liquid. This EMSURE grade product is a "multi-standard" reagent, meticulously tested to comply with the American Chemical Society (ACS), ISO standards, and the European Pharmacopoeia (Reag. Ph Eur). With an assay of at least 99.9%, it is essentially free of water and trace organic impurities. It is indispensable for laboratory procedures where the presence of water or denaturants would interfere with results, such as in DNA/RNA precipitation, histological staining, preparation of standard solutions, and as a mobile phase in high-performance liquid chromatography (HPLC).
Advantages
- Exceptional purity (≥99.9%) for highly sensitive analytical and diagnostic methods.
- Multicompliance with ACS, ISO, and Ph Eur ensures global regulatory acceptance and laboratory standardization.
- Extremely low evaporation residue and strictly controlled levels of acids, alkalinity, and heavy metals.
- Part of the EMSURE® line, offering comprehensive documentation for audit-readiness and quality assurance.
- High transparency in the UV range, suitable for spectrophotometric applications.
