The NEW Differential Refractive Index Detector for HPLC, GPC/SEC

The new Refractive Index Detector RI 2012 series provides a consistent enhancement of the already successfully established Refractive Index Detector models RI 2000 and RI 2000-F.

The Refractive Index Detector RI 2012 series offers users 3 times higher sensitivity, (compared to RI 2000) stability and reproducibility required for optimal refractive index detection in HPLC and GPC/SEC

The new Refractive Index Detector RI 2012 series provide autopurge and autozero capabilities, as well as RS-232 and USB communication to acquire data directly without using any external signal interface.

Refractive Index Detector RI 2012 detectors are available for:

micro
analytical
