Automatic Refractometer EZL-AR171 Catalog

EziLab supplies the Automatic Refractometer EZL-AR171 for pharmaceutical laboratories that need precise refractive index measurement with active Peltier temperature control built in. Covering a 1.30000-1.70000 nD range, this digital refractometer measures refractive index for raw material identification, concentration determination, and purity verification across pharmaceutical formulations and chemical solutions. That wide range covers the refractive index span of most common pharmaceutical and chemical liquids, from water-based solutions at the lower end through denser organic compounds and oils at the upper end, on a single instrument rather than requiring different refractometers calibrated for different index ranges. Peltier control is what makes readings genuinely comparable across different testing sessions — refractive index is temperature-dependent, so without active thermal control, ambient temperature drift between measurements would introduce variability into results unrelated to the sample itself, an especially relevant point for pharmaceutical QC work where results need to match reference values measured under standardized conditions. Pharmaceutical quality control programs verifying raw material identity or checking formulation concentration against specification get temperature-stable, repeatable readings rather than results skewed by lab temperature fluctuations. See the Digital Refractometer and Automatic Refractometer ranges for precise refractive index testing needs across USA pharmaceutical laboratory settings.
