- A bottle of immersion oil (about 5ml)
A drop of immersion oil between the slide and condenser, and between the slide and objective lens, provides a distortion-free path for light. Safe for all lenses, this light-viscosity immersion oil will not dry out the slides or optics. The refractive index is 1.5150, the same as that of glass. It can be easily cleaned from slides with a bit of xylene on a lens tissue and is supplied in a bottle with applicator tip so no pipette is necessary.
