Immersion Oil Type FF

Type FF has virtually no background fluorescence which makes it ideal for observing low levels of fluorescence. 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.
