Merck - 1081102500 - Tetrahydrofuran

  • Item #: 6310087
  • MFR SKU: 1081102500
Technical Specs
  • Catalogue Number 108110
  • Synonyms THF, Tetramethylene oxide, Oxolane, Butylene oxide
  • Overview Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol ® 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 ® solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph Eur and ACS.
