Cargille™ Type 300 Immersion Oil for Automated Hematology Systems

Optical and physical properties


The physical properties of immersion oil are critical to the proper operation of Automated Hematology Systems. Cargille TYPE 300 Immersion Oil is PCB-FREE, and manufactured to meet exacting performance requirements which are specifically and clearly displayed on each and every product label, including:
  1. OPTIMUM REFRACTIVE INDEX
    Light passes through a vacuum at a constant speed. When light is transmitted through liquid, such as immersion oil, its speed is altered. The amount of alteration depends on the optical properties of the liquid. The measurement of this effect is known as the Refractive Index. The morphological analyzer in Automated Hematology Systems is programmed to scan blood cells at specific wavelengths. When immersion oil is not manufactured to precise specifications, its use can affect cell recognition.

    CARGILLE IMMERSION OIL TYPE 300 and all Cargille Immersion Oils are manufactured to qualify control standards that are more demanding than those required by instrument manufacturers, the FDA, and the international standards organizations DIN and ISO.

  2. CONTROLLED COLOR ADSORPTION
    Part of an Automated Hematology System's recognition program includes color analysis. This analysis is performed by scanning a blood cell with a narrow beam of white light. Immersion oil can adsorb various spectra of light. Cargille Immersion Oils are developed specifically to insure that their adsorptive properties will not interfere with cell recognition.

  3. APPROPRIATE VISCOSITY
    The flow characteristics of immersion oil are also important to the operation of an Automated Hematology System. As the system scans the slide, the objective assures proper focusing of the microscope. Sharp focusing is only achieved if the oil maintains an even meniscus under the moving objective.

    Cargille TYPE 300 and all Cargille Immersion Oils are manufactured to exacting and consistent viscosity tolerances, assuring users of Automated Hematology Systems optimum instrument operation from batch to batch and bottle to bottle, for the life of the instrument.
