Opis

General description

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.

Application

• Phenylalanine Ammonia Lyase Activity Research: A study investigated the mutase-like activity of phenylalanine ammonia lyase from Anabaena variabilis, demonstrating the utility of buffer concentrate in biochemical assays to stabilize enzyme activity during the research (Weise et al., 2018).



• Studying Amyloid Precursor Protein: A study used buffer concentrate for experiments involving the amyloid precursor protein C-terminal fragment C100, noting its importance in maintaining the stability of protein conformations during interactions with γ-secretase modulators (Botev et al., 2011).
