Refractometer for Flavor Fragrance Labs

  • Rudolph’s R837 AutoFlex Sampler can be loaded 50 – 16 x 100mm Test tubes. 70 – 13 x 100 mm, or optionally dozens of sample vial configurations and capacities.
  • Combine Refractive Index measurements with a polarimeter, density meter, PH, and colorimeter for simultaneous measurements of:
    • Density/Specific Gravity
    • Optical Rotation/Specific Rotation
    • Color
    • Refractive Index / RI
    • PH
  • Up to three different rinse solvents available for use; fully programmable
  • Emergency samples measured at any time without stopping the AutoSampler or moving sample vials
  • Data can be saved in Excel or PDF formats for integration into the laboratory LIMS or SAP system

Refractometer Model Specification Features and Benefits
 Food Refractometer  Measurement Range: 1.26 – 1.70 RI; 0 – 95% Brix
Accuracy:0.0001 RI; 0.1 Brix
Electronic Temperature Control: Fixed temperature selection: 20°C and 25°C
 Many aromatic substances such as Cinnamic/Aldehyde have refractive indices above 1.60 RI. For this reason,most flavor/fragrance labs choose a wide RI range refractometer like the J57WR.
J57-open-thumb  Measurement Range: 1.26 – 1.70 RI; 0 – 95% Brix
Accuracy:0.00004 RI, 0.03 Brix
Electronic Temperature Control: Fixed temperature selection: 20°C and 25°C
 Excellent model for the flavor and fragrance industries. Designed to be used with automation. Not suitable for waxes or VERY high viscosity samples. Seen above in combination with optical rotation, density/SG and color.
 Refractometer J257  Measurement Range: 1.26 – 1.70 RI; 0 – 100% Brix
Accuracy:0.0001 RI; 0.1 Brix
Electronic Temperature Control:Flexible temperature selection between 15°C – 70°C
This is our most popular stand alone model for the flavor/fragrance industry. Its wide RI range 1.2 – 1.7 measures all known products. Its non-contact sample cover improves performance for evaporative samples. Presser can be upgraded to allow automation in the future.
Refractometer J357  Measurement Range: 1.26 – 1.70 RI; 0 – 100% Brix
Accuracy:0.00004 RI; 0.03 Brix
Electronic Temperature Control:Flexible temperature selection between 15°C – 100°C
More accuracy and features generally needed by the industry. This model is sometimes chosen when the customer sells most of their product to the pharmaceutical industry and wants 21CFR Part 11 compliance.
 Measurement Range: 1.26 – 1.72 RI; 0 – 100% Brix
Accuracy: 0.00002 RI; 0.015 Brix
Electronic Temperature Control: Flexible temperature selection between 10°C to 100°C with ±0.01°C reproducibility.
Rudolph’s most capable refractometer. Perfect for today’s highly regulated laboratories offering full 21CFR Part 11 compliance. Rudolph Research is the first manufacturer to offer  Smart Measure™a system that notifies the operator of the quality and status of the sample load, as well as the sample well status. This assists the operator in producing more accurate readings, and actually documenting that the sample was properly loaded. The J457 Refractometer is available in 3 configurations J457 SC – Standard Bench-top, J457 WC – Wall Mount, and the J457 FC – Factory Configuration. These configurations allow the measurement unit to be isolated from the display unit, thus protecting it from harsh environments and messy spills.
