Fluorolube® is a fluorinated hydrocarbon solvent that is ideal for preparation of samples to be run from 4000 to 1360 cm-1 where it is non-absorbing, except at 2321.9 cm-1. This very high viscosity liquid will make virtually any sample adhere to a crystal substrate, making it ideal for preparing mulls with Real Crystal™ IR cards or with water polished crystal blanks. To prevent contamination, Fluorolube® comes in a convenient size squeeze bottle, which contains enough solvent to produce over 100 samples
