Cargille Refractive Index Liquids have become standard items in many laboratories as their applications have expanded from routine mineralogical identifications and quality control. New and broader uses in many more fields such as chemicals, engineering, medical, forensic, optics, and instrumentation are continuously discovered. Many special requirements for specific applications have created a need for more technical data, new formulations, extended ranges, smaller increments and higher degrees of precision.

Since 1942, Cargille Laboratories, Inc. has been filling this growing need. And today, the largest and most comprehensive assemblage of refractive index liquids - over 250 stocked items - are available for science, industry, medicine, and education. For specialised and unusual applications, many more can be formulated and others are routinely researched in anticipation of new needs.

Chlorofluorocarbon (CFC) components used in some Cargille optical liquids have physical properties that are harmless to the ozone layer, unlike those found in refrigerant gases, propellants, and solvents, which are destructive. The components used by Cargille Laboratories have vapour densities ten times that of air, are relatively nonvolatile, and have boiling points at least 100 deg. C higher than the highest-boiling CFC of those listed for removal from commercial use by the Montreal Protocol.


Cargille Refractive Index Liquids have a broad range of applications in diversified fields. The following table briefly illustrates some of the typical areas of use.

IDENTIFICATION Identify minerals, ores, chemicals, specimen fragments, plastics, gems, translucent or transparent solids by microscopic immersion techniques.
MOUNTING MEDIA Temporarily mount specimens in various index media for matching or contrasting index combinations.
Mount specimens and thin sections in a stable, viscous, nondrying index of refraction liquid to permit sample rotation by shifting cover glass for more comprehensive examination. (Cargille MeltMount)
OPTICAL ANALYSIS Microscopically study solids by dispersion staining, focal masking, and double variation refractometry techniques with high dispersion liquids.
REFRACTOMETRY Calibrate refractometers and other optical instruments.
EDUCATION Instruct and exhibit principles and applications of refraction.
SPECTROPHOTOMETRY Determine refractive index of specimens by referral to calibration curves relating wave length to index of refraction.
STRAIN ANALYSIS Examine stress and strain effects of transparent or translucent items; molded, formed, curved or intrinsically shaped parts by polariscopic immersion technique. (Cargille Immersion Liquids)
TOXEMIA Identify salts precipitated from body fluids and measure relative amounts of sodium and potassium chloride for indicating toxemia.
OPTICAL COUPLING Couple optical elements with liquids formulated for refractive index and viscosity.
OPTICAL LENSES Obtain unique optical properties of hollow lenses by filling with index of refraction liquids.
ELECTRO-OPTICS Examine and preserve cathode coating without stripping or re-immersion by utilizing oils matching index of crystals.
POLLUTION Identify particles and particulates from air or water.
FLUID FLOW Photograph flow patterns by filling test system with refractive index liquids having suspended "beads".
