What are refractometers and what to ask when buying these instruments for your laboratory

Versatile Analyzers, from QC to LC

Refractometry is thought to be a limited analytical technique that works best with binary solutions—for example, salt or sugar solutions—where it excels at precise concentration measurements.

2014 Product Resource Guide: Refractometers

Refractometers come in all sizes, shapes, capabilities, and prices. Some readers may recognize refractometry as a “high school” analysis method or a specialized technique for measuring specific analytes like sugar in water. Increasingly, lab and process engineers employ refractometry to provide quick measures of key quality attributes that under normal circumstances would require much lengthier assays on significantly more expensive equipment.
