RXA 156/170

The RXA 156 and RXA 170 modules are equipped with a micro flow cell and an integrated Peltier thermostat ensuring accurate and automatic temperature control. Fast and non-destructive measurements, requiring only small sample volume, yield to refractive index (RI) and RI-derived results. Both RXA types can be used as a module in measuring systems.

$Density and Refraction Index Analyzer RXA 156 / RXA 170$

All the advantages of modular design

Combination with a DMA 4100/4500/5000, DSA 5000 or Soft Drink Analyzer 2 to a measuring system
DMA, DSA or Soft Drink Analyzer 2 serve as the control and evaluation unit of the system
The instruments can be used separately if required
For pasty or expensive samples, manual filling of the refractometer is possible
Simple adjustment of both instruments using air and water in one procedure
Automatic filling and cleaning of both instruments with an optional sample changer

One measuring cycle, two (three) sample parameters

Save time by simultaneously determining the density (and sound velocity) and refractive index
Fast and reliable results

Reliable measuring methods

Established U-tube method for measuring density
Highly accurate measurement of the angle of total reflection for determining the refractive index
