General description

EMSURE grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE provides worldwide best and most extensive product specifications. We declare our EMSURE range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

Application


  • In Situ Synthesis of Environmentally Friendly Waterborne Polyurethane Extended with Regenerated Cellulose Nanoparticles for Enhanced Mechanical Performances: Ethyl methyl ketone is utilized in the synthesis process of eco-friendly polyurethane materials, contributing to the development of sustainable composite materials with improved mechanical properties (Choi et al., 2023).

  • Comparative Studies on the Physicochemical and Volatile Flavour Properties of Traditional Deep Fried and Circulating-Air Fried Hairtail (Trichiurus lepturus): Ethyl methyl ketone′s solvent properties are utilized in the analysis of food flavors, particularly in comparing cooking methods and their impact on flavor profile, which is vital for food science research (Ding et al., 2022).
