Key Features
Built-in Peltier Temperature Control
Controls sample temperature internally, removing the need for a separate constant-temperature water bath and improving comparability between readings.
High-Accuracy Brix and Refractive Index
Supports precise raw-material, intermediate and finished-product checks. RX-5000α-Plus is the preferred choice where very small Brix differences matter.
FDA 21 CFR Part 11 Support
ATAGO RefractoSoft is included in standard delivery for the core RX-α models and is designed to support controlled electronic-record workflows in regulated laboratories.
Pass/Fail and Measurement History
Upper and lower control limits help operators identify out-of-specification readings quickly, while stored results support review of recent measurements.
Programmable User Scales
Allows laboratories to display concentration values derived from refractive index for selected products, formulations or raw materials when a suitable correlation is available.
Measurement Modes for Different Samples
Available modes support maximum accuracy, faster results, periodic readings and difficult samples such as emulsions, depending on model and application.
Beverage-Focused Flat Sample Stage
RX-5000α-Bev replaces the conventional well with a flat stage, making sticky beverage samples easier and faster to wipe away.
Wide-Range and High-Temperature Options
RX-7000α and RX-9000α expand the refractive-index range and temperature-control range for oils, high-melting samples, fragrances, solvents and chemical products.
USB and RS-232C Connectivity
Measurement data can be transferred directly to a PC, printer or LIMS, supporting traceable record-keeping in routine laboratory workflows.
Application Example
Beverage and Juice Quality Control
Brix testing of fruit juices, concentrates, syrups, soft drinks, dairy-based beverages and process samples. RX-5000α-Bev is especially relevant where frequent measurement and rapid cleaning are required.
Pharmaceutical QC and Raw Materials
Refractive-index or concentration checks for syrups, solvents, alcohols, flavours and incoming raw materials at controlled temperatures. RefractoSoft supports regulated electronic-record workflows.
Chemical and Industrial Laboratories
Concentration or refractive-index measurement of solvents, acids, alkalis, surfactants, resins, process chemicals, inks and formulated products where a valid RI-to-concentration relationship exists.
Oils, Flavours and Fragrances
RX-7000α and RX-9000α support higher refractive-index and elevated-temperature measurement for oils, fats, aroma compounds and organic solvents.
Food Ingredients and Formulation
Routine control of sauces, jams, honey, dairy products, flavours, extracts and ingredient solutions during incoming inspection, formulation and finished-product release.
Research, Teaching and General QC
A dependable benchtop platform for laboratories requiring controlled-temperature Brix and refractive-index measurements across changing sample types.

Frequently Asked Question
The instruments directly measure refractive index and calculate Brix. They can also display programmed user scales where a verified relationship exists between refractive index and the required concentration value.
RX-5000α is the standard choice. RX-5000α-Plus is preferred where higher Brix accuracy is important. RX-5000α-Bev is particularly practical for frequent beverage testing because its flat sample stage is easier to wipe clean.
Both models provide the wider refractive-index rangeand temperature control up to 70°C. RX-9000α provides higher measurement accuracy and is preferred where greater precision is required across the broader range.
No. The RX-α series uses an internal Peltier thermo-module to control the sample temperature within the specified operating range.
ATAGO states that RefractoSoft is included in the standard delivery of the core RX-alpha models. The software supports FDA 21 CFR Part 11 electronic-record workflows, but the customer must still configure and validate the complete regulated system under its own procedures.
Yes. The RX-α series can measure pharmaceutical raw materials where refractive index or a validated concentration relationship is appropriate. Model selection should consider the required temperature, accuracy, sample compatibility, and testing method.
The instrument can display a user-defined concentration scale when reliable refractive index versus concentration data is available. The scale must be developed and validated for the specific chemical and temperature range.
Yes. The core RX-α models provide RS-232C computer output. If USB, Ethernet, LIMS, or middleware connectivity is required, the appropriate interface should be specified during the quotation stage.
Routine accuracy is typically verified by zero-setting the instrument with suitable water and checking performance using appropriate refractive index or Brix reference solutions in accordance with the laboratory’s SOP.
Yes. CWTC provides model selection assistance, supply, installation, operator training, software guidance, reference solution selection, preventive maintenance, and technical support according to the agreed project scope.
