FDA 21 CFR Part 11
Software is available to support your FDA 21 CFR Part 11 compliance.
Ergonomically Designed Layout
The RX- a series was designed with ease of use in mind. Extensive research was performed in the design phase to ensure an ergonomic interface that made operation easy while maximizing efficiency.
4 Measurement Mode Options
MODE-1: For maximum accuracy
Displays the measurement value once the sample reaches the target temperature.
MODE-3: For no 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-2: For fast results
Measures refractive index and temperature at fixed intervals and displays the estimated measurement value at the target temperature.
MODE-S: For emulsion samples
Displays the measurement value once a certain level of sample stability is achieved.

3921 Digital Refractometer RX-007α | Application Examples
Refractive Index
Refractive Index is a common quality standard measure for pharmaceutical or chemical products. Measurements need to be taken at a constant temperature, commonly 20°C, 25°C, and 40°C. The RX-α units are equipped with the internal Peltier Thermo-Module, and measurement starts once the target temperature is reached.

| Petroleum and Organic Solutions | Oils and Fats | Detergents |
Brix
Brix is measured for quality control purposes in the food and beverage industries. The RX-α units are widely used for fruit juice, condiments, jams, and honey. The RX-007α (minimum indication 0.001% Brix) is used for tea and unsweetened drinks.
 |  |  |
| Beverages and Fruit Juice | Jams, Honey, Liquid Sugar, Syrups | Condiments, Sauces, Soups |
Concentrations
The concentrations of industrial solutions are often monitored. Examples include water-based cutting oils and cleaning solutions, hydrogen peroxide, coolants, and alcohol solutions. Although the Brix scale is commonly used, user scales can also be programmed to display converted sample values.
