Cargille Immersion Oils

Cargille Immersion Oils are required for high magnification and to obtain sharp images with clear resolution. These immersion oils meet ISO standards for quality and are PCB-free.

Type A (low viscosity) and Type B (high viscosity) are used for normal microscopy applications with viscosities from 150-1250 centistokes. The greater the gap between cover glass and objective, or condenser and slide, the more desirable high viscosity becomes.

Types A and B are virtually interchangeable and are miscible with each other for intermediate viscosities. The deciding factor in choosing between them is the optimum viscosity for your particular application.
