Automatic Temperature Control

The integrated Peltier temperature control quickly heats up or cools down the measurement cell, maintaining the sample reliably at the desired temperature.

Status Light

The status light of the instrument shows if it is ready for a measurement (green), busy (blinking), or waiting for operator action (orange).

Automated Sampling, Rinsing and Drying

Automating workflows saves time, reduces costs and improves safety. The R4 is compatible with a large portfolio of autosamplers including solutions for single or multiple samples, and samples which are solid at room temperature.

Upgradable System

The Excellence R4 can be upgraded to a dedicated automatic multi-parameter system combining density, refractive index, pH, color, titration and more to save time, increase data quality and prevent any alteration of samples between individual analyses.
