OleiniTec Nordic AB offers both laboratory instruments and in-line instruments for analysing Brix. Degrees Brix (°Bx) is the sugar content of an aqueous solution, where one degree Brix is equal to 1 gram of sucrose in a 100 gram solution. If the solution contains dissolved solids other than pure sucrose, then the °Bx only approximates the dissolved solid content. The degrees brix (°Bx) is traditionally used in the wine, sugar, carbonated beverage, fruit juice, and honey industries.

Rudolph Research Analytical  is a leading analytical laboratory instrument supplier that manufacture precision quality, benchtop refractometers for analysis of Brix.


Main refractometer for brix analysis features:

  • Shallow refractometer sample well

Refractometer measurement accuracy is only as reliable as the cleanliness of the sample well. Thus, hard to clean sample wells can lead to inaccuracies. Using higher quality optics Rudolph was able to design a sample well that is very shallow and smooth. The result is more accurate measurements due to significantly sample cross-contamination

  • Advanced sample temperature control

Rudolph’s sample well has an electronic heating and cooling system. This greatly improves results and is simple to use. Some applications require highly controlled temperature. A temperature-controlled sample cover can be added to ensure even and accurate temperature stability. Thus, temperature-controlled samples from both the top and bottom allow for the most accurate measurement.

  • Durable Sapphire Prisms with Long-life Light sources. Low Life of instrument cost.
  • 3 Year Warranty
  • 20 Year Support Guarantee

Rudolph Research line of Automatic Refractometers


Maselli is a leading supplier of both inline refractometers and laboratory refractometers for measuring refractive index and brix, focusing on the beverage industry. The refractometers are accurate, robust, compact and  easy to use both in the laboratory and out at the line.


LP10 – Laboratory Package for Beverages


The LP series is a complete range of optical sensors for the beverage industry for measuring refractive index, brix, fresh brix, diet, CO2 and O2. The design is modular: the system can be composed of different analysis modules based on the needs and they are all handled by a single control panel. It is possible to upgrade the initial configuration with additional analysis modules at any time. Being used as bench top analyser, the LP10 includes a semi-automatic sampler for picking the beverage samples from all types of containers.


The UR24 digital refractometerBeer analyzer is a stand-alone unit designed for simple installation in-line or in a tank. The analyzer provides a continuous measurement of concentration that can display the result in Brix, nD, or % concentration with high accuracy. The UR 24 also features a user programmable scale for specific applications.


The UR62 digital refractometer is a probe designed for simple installation in-line or in a tank or vessel. It continuously measures concentration and displays and outputs the result in Brix or nD or % concentration with basic accuracy. The UR62 will signal to the process when concentration is outside of specifications or has reached its target end point by means…


The URX1 digital refractometer is designed specifically for hazardous areas up to Zone 0: the equipment certificate is ATEX II 1 G – EEx ia IIB T4. You may simply install the unit in-line or in a tank or vessel. It continuously measures concentration and displays and outputs the result in Brix or nD or % concentration with high accuracy


The IB08 beverage analyzer is a complete inline quality control system. The analyzer measures carbonated soft drink (Brix, Diet, CO2 and O2) as well flavored waters. The analyzer is based on optical technology and is virtually maintenance free. The Brix and Diet readings are measured via refractive index and infrared technology is used for measuring CO2 (pressure / temperature CO2 sensor is also available upon request).

The beverage analyzer IB07 is the only 100% in line system able to measure accurately Bx and CO2 of any regular carbonated beverage including fruit juice with fibers, energy drinks and mineral waters. The equipment is based on optical technology: refractive index for Bx measurement and infrared for CO2 one. Both analyzers do not have any drift in the time.


The DR10 Lab differential refractometer is an innovative system for measuring the concentration of diet or sugar-free carbonated soft drinks. A single analyser that for concentration measurement can replace HPLC, spectrophotometry, titration and other manual systems and methods. The system is simple to use and provides accurate and consistent results without the need for a skilled operator. The analysis cycle is completely automatic and requires no sample preparation. There are no chemical reagents required or routine consumables to be replaced. While designed for the laboratory the system is rugged enough to be used at-line for fast results for samples taken directly from the line. Using this technology, it is possible as well to measure diet syrups and regular beverages.
