Description

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

Ethylene Glycol is used as a solvent :

• in diode laser-based detection of single molecules in solutions.
• and reducing agent in the synthesis of gold nanoparticle.

Additionally, ethylene glycol is also used an important precursor to polyester fibers and resins.
