The Cole-Parmer Refractometer 1.47–1.87 RI offers uncompromising precision at an economical cost, meeting ASTM D 1416-89, Section 38-46 standards. This Abbe refractometer is designed for highly accurate refractive index measurements of liquids and solids, ideal for diverse laboratory applications.
Product Features
- Measures refractive index range from 1.4700 to 1.8700 RI, accommodating polymers, films, resins, glass, adhesives, chemicals, and more
- Complies with ASTM D 1416-89, Section 38-46 requirements
- Main prism rimmed with corrosion-resistant stainless steel for durability
- Built-in 589 nm illuminator for stable, monochromatic light (models 02939-00, -02 include LED light source)
- Frosted secondary prism directs light evenly and lifts up for easy placement of solids and viscous liquids
- Color compensator knob allows boundary line adjustment and fine-tuning for higher clarity and resolution
- Four 9-mm OD ports allow connection to a constant-temperature bath (using 6 to 7-mm ID tubing) to maintain temperature at both prisms
- Thermistor thermometer built into the main prism with digital temperature display (0 to 50°C, ±0.2°C accuracy)
- Built-in desiccant chamber removes moisture from internal optics to ensure a clear view of scales
- Model 02939-06 is specifically designed to measure refractive index only in both liquid and solid samples
Benefits
- Wide RI range suitable for various industrial and research materials
- Corrosion-resistant stainless steel components extend instrument life
- Stable, monochromatic illumination improves measurement accuracy
- Temperature control features guarantee consistent results
- Moisture control prevents optical obstruction for reliable readings
