Fluid is widely used for drum scanners, it keeps the film in focus
and can help in hiding scratches, Newton rings and dust.
Talking about flatbed scanners, Epson Perfection v750 Pro scanners can
use  the "Fluid mask Accesory" (it is/was sold separately) and the
v700 could also use it, becoming the only difference for both scanners
the 750 lenses coating; the fluid is specially useful for B&W negs
because the digital ICE technology to remove scratches, dust etc. does
not work with B&W negs, the v700/750 fluid helps to avoid Newton rings
too.

The fluid for the v750 and v700 is a hazardous liquid called "KAMI SXL
2001", it is highly flammable and contact with the skin and eyes must
be avoided. Results are good to get a better scan, but it requires
practice, f.e. the fluid tends to evaporate very quickly.
