• Resumen

  • If silicone greases are used on the standard taper joints of round bottom flasks, they will eventually get inside the flask, contaminating the contents and introducing spurious peaks into the IR and NMR spectra of samples. Removal of these deposits with solvents or conventional cleaning solutions is difficult. This article describes a fast and efficient method for removing the deposits.
