Benchtop Refractometers (ATAGO)

For years, ATAGO has been setting standards in laboratory refractometers with the successful “RX-i” device family. There have been some innovations since 2020. The RX-i series from ATAGO is now even more stylish and functional. Intuitive touchscreen technology makes navigation and operation amazingly easy.

In addition, the areas of application have also been expanded: Apart from stainless steel the sample stage is now also available in PTFE, PEEK or Hastelloy®. Hence, aggressive substances such as concentrated hydrochloric acid can be measured.

The RX-i series comes pre-programmed with 23 of the most commonly used concentration scales, e.g. for glucose, fructose, honey moisture, NaCl, NaOH, H2O2, ethyl alcohol, ethylene glycol, propylene glycol, urea and others.

All devices of the RX-i series are also equipped with an USB drive and various self-diagnostic functions. Software according to FDA regulation 21 CFR part 11 is included in the standard scope of supply.
ATAGO offers a 2-year warranty due to the excellent quality and GIMAT extends it by 1 year for all devices that have been purchased from us.

The RX-5000i offers the best value for money in the class of laboratory refractometers.

Measuring range: refractive index (nD): 1.32420 to 1.58000
Accuracy: refractive index (nD): ± 0.00004 and ± 0.03% Brix.

The RX-5000i-Plus is ATAGO´s flagship model and the most accurate refractometer in the world.

Measuring range: refractive index (nD): 1.32420 to 1.58000

The measuring accuracy of the RX-5000i-Plus is remarkably high. Refractive index (nD): ± 0.00002 nD and ± 0.010% Brix.

The RX-7000i and RX-9000i are the wide range models in ATAGO’s RX-i series and available as alternatives to the RX-5000i and RX-5000i. The special feature: the greatly extended measuring range. Aromas, fat and oils can also be measured reliably and with high precision.

RX-7000i
Measuring range: refractive index (nD): 1.29980 to 1.71500
Accuracy: refractive index (nD): ± 0.0001 and ± 0.1% Brix.

RX-9000i
Measuring range: refractive index (nD): 1.29980 to 1.71500
The RX-9000i-Plus measures with a remarkably high accuracy: refractive index (nD): ± 0.00004 and ± 0.030% Brix (up to 50%) or ± 0.050% Brix (over 50%).

The following measuring modes are available:

Mode-1 for maximum accuracy

Displays the measurement value when the sample has reached the target temperature.

Mode-2 for quick results

Measures the refractive index and the temperature at specified intervals and then displays the calculated measurement value at the target temperature.

Mode-3 without temperature control

Provides an option to turn the thermo-module off. Without temperature control, the measurement value is displayed in 4 seconds after the START key is pressed.

Mode-S for emulsion samples

Displays the measurement value as soon as a certain level of sample stability is achieved.

Mode-T for measuring low Brix liquid samples

Only on the RX-5000i-Plus. MODE-T is recommended for users who place importance on obtaining highly repeatable results (Brix 0.001%) with low Brix samples, e.g. teas.
