Description

Description générale

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

• Biofiltration of n-butyl acetate with three packing material mixtures, with and without biochar: This research explores the efficiency of biofiltration systems using n-butyl acetate, emphasizing sustainable environmental management practices to mitigate solvent emissions in industrial settings (Halecký et al., 2024).


• Biphasic alcoholysis coupled with high-speed countercurrent chromatography for high performance on separating phorbol from Croton tiglium Linn extracts: Illustrates the application of n-butyl acetate in enhancing the efficiency of extraction and purification processes, critical for pharmaceutical and chemical research (Fan et al., 2023).
