一般描述

Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol<TMSYMBOL></TMSYMBOL> solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol<TMSYMBOL></TMSYMBOL> solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified.

应用

  • Investigation of anti-depression effects and potential mechanisms of the ethyl acetate extract of Cynomorium songaricum Rupr. through the integration of in vivo experiments, LC-MS/MS chemical analysis, and a systems biology approach.: This article describes the application of ethyl acetate in the extraction of antidepressant compounds, integrating chemical analysis with biological testing to explore therapeutic potentials (Zhang et al., 2023).
  • Steroid Components of Marine-Derived Fungal Strain Penicillium levitum N33.2 and Their Biological Activities.: The use of ethyl acetate for extracting steroid compounds from marine fungi is discussed, focusing on the biological activities and potential pharmaceutical applications of these extracts (Hoang et al., 2023).
  • Streptomyces sp. MNP32, a forest-dwelling Actinomycetia endowed with potent antibacterial metabolites.: This study details the extraction of antibacterial compounds using ethyl acetate from a forest-dwelling Actinomycetes species, contributing to the discovery of new antibiotics (Konwar et al., 2023).
