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  NVH viscosity immersion oil will not dry out the slides or optics. The refractive index is 1.5150, the same as that of glass.

• Supplied in a bottle with applicator tip so no pipet is necessary.
• Immersion oil is most safely removed from Microscope lens and slides by using only lens tissue, without employing any solvents.
