RI Liquids HD-Half Set of 31 – RI 1.500 to 1.800

Description

The High Dispersion RI Liquids HD-Half Set of 31 provides optical microscopists, materials analysts, and forensic labs with a wide-range refractive index toolkit. Specifically formulated for general dispersion staining and polarised light microscopy (PLM), these high-dispersion liquids enable fast, reliable identification of unknown minerals, synthetic fibres, pharmaceuticals, and inorganic chemicals.

Each liquid in this 31-bottle set is manufactured to exact optical tolerances by Cargille Laboratories, with refractive indices verified at 25°C using 589.3 nm (sodium D-line) illumination.

Key Features & Benefits

• Wide Refractive Index Coverage: Spans RI 1.500 to 1.800 in uniform 0.01 steps, allowing precise matching across a broad spectrum of organic and inorganic materials.

• High Optical Dispersion: Engineered with steep dispersion curves to generate sharp, vivid dispersion staining colours for clear optical contrast.

• Chemical Stability: Low-volatility, non-reactive formulations ensure long shelf life and consistent index integrity.

Primary Applications

• Dispersion Staining Microscopy: Enables rapid optical identification of unknown particles and crystalline materials.

• Geology & Mineralogy: Essential for refractive index testing of translucent minerals, rocks, and soil samples.

• Forensic Analysis: Used in trace evidence profiling for glass fragments, synthetic fibres, and chemical residue.

• Pharmaceutical QC: Assists in analysing active pharmaceutical ingredients (APIs), polymorphs, and contaminants.

• Materials Science: Supports optical characterisation of polymers, ceramics, pigments, and synthetic chemicals.
