ABSTRACT:
An immersion oil formulation for use in microscopy and related optical fields consists of a blend of a dialkyl phthalate, a butyl benzyl phthalate and chlorinated paraffin. The compounds, when blended, possess a desired optical property including a refractive index of 1.518 or thereabouts and an extremely low fluorescence enabling the immersion oil to be utilized in the field of fluorescence microscopy. The resultant blend also possesses a low toxicity and therefore eliminates all the disadvantages of prior art immersion oils which contain PCBs or which exhibit undesirably high auto fluorescence.
