Immersion oils

Immersion oils are essential for routine laboratory work, especially in hematology, cytology and microbiology. They are commonly used for high scale magnifications in order to secure high resolution and a clear image. There are several types of immersion oils that differ according to viscosity and certain properties required by different microscopy techniques. They all have a common refractive index of 1.5150, equal to the refractive index of glass.
