Flavor and Fragrance Refractometers
Fragrance Refractometers and Flavor Refractometers Industry Description
Flavor and Fragrance refractometers are commonly used in the cosmetic industry where materials are traded worldwide. Essential oils are distilled from plants in some of the most remote corners of the globe. Innovation laboratories make analogs of traditional flavors or even whole new materials. The two most common specifications in certificates of analysis are Specific Gravity(SG) (density) and Refractive Index(RI).
Reasons to Choose Rudolph
- Wide range of 1.26 RI to 1.70 RI allows measurement of all currently approved compounds.
- Built-in temperature control provides more accurate results than relying on temperature correction models.
- Flat, easy clean prism means better results even when used by non-laboratory trained operators.

Feature Highlight
Automation Flexibility
- Rudolph’s R837 AutoFlex Sampler can be loaded with 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 are available for use; they are fully programmable
- Emergency samples are 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 |
|---|---|---|
 |
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 Fragrance refractometer like the J57WR. |
 |
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. |
 |
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 of 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. |
 |
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 are generally needed by the industry. This model is sometimes chosen when customers sell most of their products to the pharmaceutical industry and want 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. |
