Nikon Silicone Immersion Oil 30cc

Nikon Silicone Immersion Oil (MXA22179) is a specialty immersion medium formulated specifically for use with Nikon's silicone immersion objectives. With a refractive index of n=1.406, it closely matches the refractive index of aqueous biological samples and living cells — significantly reducing spherical aberration when imaging deep into specimens compared to standard oil immersion (n=1.515). This makes it particularly valuable for live cell imaging, 3D confocal imaging, and deep tissue fluorescence applications where maintaining optical fidelity through the full depth of the specimen is critical. Unlike standard immersion oils, silicone oil also exhibits excellent temperature stability, maintaining consistent optical performance across a broader temperature range — important for live cell work at physiological temperatures. For use exclusively with Nikon silicone immersion objectives.
