It is highly stable, water white, and non-hydroscopic. Type FF can be substituted for all other fluorescence microscopy immersion oils in nearly all fluorescence applications.<\/span>_x000D_\n_x000D_\n* Immersion Oil Type LDF<\/strong>_x000D_\nExtremely low fluorescence is achieved by Type LDF. It is the replacement of choice for the DF which is no longer being manufactured. The LDF possesses the highest resolution of the oils for fluorescence applications.<\/span>_x000D_\n_x000D_\n* Immersion Oil Type HF<\/strong>_x000D_\nType DF has been discontinued by Cargille. As an alternative we are offering either a new Immersion Oil called HF which would provide low fluorescence and the correct optical properties or you can use our FF which has virtually no fluorescence but slightly less than ideal optical properties._x000D_\n_x000D_\n\u00a0_x000D_\n_x000D_\nOPTICAL & PHYSICAL PROPERTIES_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n_x000D_\n
