Cargille immersion oil, type B (EMS)

For Normal Light Microscopy use Immersion oil Types A and B.

Types A & B Immersion Oils
These two types practically vary only in viscosity and they are interchangeable and miscible with each other for intermediate viscosities. Produced in larger quantities than other types, Types A and B are the most economical. The deciding factor in choosing between them is the optimum viscosity for your particular application.

Type A, at 150 centistokes, reduces any tendency to trap air, especially helpful to beginning students. Air bubbles cause image degradation. Also Type A is less sticky and easier to clean up.

Type B, at 1250 cSt, is thick enough for viewing multiple slides with one application. This saves time during batch processing. Type B is the most used of these immersion oils. For a greater gap between cover glass and objective, (or condenser and slide) type B is more desirable.

Cargille was first to introduce PCB-Free immersion oils in 1972. Though all immersion oils are now PCB free, no other immersion oil meets FDA criteria; and Cargille's exceeds ISO, DIN and all instrument manufacturer's standards. Minimum shelf life of these immersion oils is 5 years and can be twice that.

Blending Oils from the Miscible Group: The Miscible Group of immersion oils is A, B, NVH and OVH. Users can easily blend any two immersion oils from the Miscible Group to obtain an immersion oil with an intermediate viscosity while maintaining the optical properties common to both. Type 37 can be blended with type B.

All Cargille immersion oils are classed as low fluorescence, however, for work with weak fluorescence, types FF and LDF.

AVAILABILITY NOTE:  We will no longer be dispensing Cargille Immersion oil. Once our stock of dispensed oils are gone, these will be sold in the 29ml/1oz, 120ml/4oz and 473ml/8oz sizes only.
