Immersion Oil

In light microscopy, immersion oil is used to increase the resolution of a microscope at high magnification using special “oil immersion” objectives. This is achieved by immersing both the objective lens and specimen in a transparent oil of high refractive index typically 1.5185.

Previously, Cedar Tree Oil has commonly been used as immersion oil to increase the resolution.

Cedar Oil has a number of disadvantages:

  1. Absorbs blue and ultraviolet light
  2. Yellows with age
  3. Can damage objectives by attacking the cement used to attach lenses and can harden if not removed immediately

Vetlab Immersion Oil has a refractive index of 1.5185 and does not have the disadvantages of Cedar Oil. However, we recommend that the oil is removed from the objective lens immediately after use by wiping with a lens tissue.



Histoclear is a solvent/cleaning agent which can be used in Microscopy to replace Xylene. Histoclear is effective for cleaning microscope objective lenses, especially oil immersion lenses, and also other optical instruments.

Histoclear is distilled from oranges, which gives it a recognisable citrus smell when opened. It is much safer to use than Xylene.
