Descripción

Descripción general

EMD Millipore offers EMPARTA grade solvents for routine tasks in analytical laboratories. EMPARTA grade solvents offer fewer test parameters than EMSURE, yet are still of high quality. EMPARTA solvents meet ACS requirements, making them ideal for a wide range of analytical applications.

EMPARTA solvents are designed for routine chemical synthesis, drying, purification, and critical labware cleaning in quality control environments. Engineered for precision, they deliver consistently reproducible results essential for rigorous validation and documentation.

Exceptional Quality Standards: These solvents meet or exceed ACS specifications, providing assurance of high quality that is crucial for accurate testing and analysis in quality control.

Consistent Reproducibility: Designed for precision, the solvents ensure that results can be reliably reproduced, which is vital for maintaining compliance and integrity in quality control processes.

Versatile Applications: Suitable for a variety of QC tasks, including analytical testing, method validation, and testing USP/NF monographs, these solvents support a comprehensive approach to quality assurance in laboratory settings.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is Biorenewable and alternative to petrochemical solvents. Ethanol is environmentally preferable green solvent and thus it aligns with "Safer Solvents and Auxiliaries" and "Use of Renewable Feedstocks". Click here  for more information.

Aplicación

Ethyl alcohol, pure can be used as a solvent in many cleaning and research applications including extraction and preparation of samples:

• To prepare a homogeneous dispersion of ZnO-Ts powder for effective separation by differential centrifugation.[1]
• In the extraction of capsaicinoids in pepper sample.[2]
• To purify and fractionate corn-stover lignin, enhancing molecular weight for improved carbon fiber production.[3]
