410 Differential Refractive Index Detector, Waters (CAT#: STEM-CPO-0727-ZJF)

The manufacturer of the 410 Differential Refractive Index Detector, Waters is Waters.
Refurbished Waters 410 RI detector complete with flow cell. The Waters 410 is designed for HPLC and GPC applications. This detector is particularly suited for determining the molecular weight distribution of polymers or carbohydrates in food products. The temperature-controlled optics and the patented countercurrent heat exchanger increase baseline stability for reproducible results. The 410 can be operated on its own or programmed from a waters controller.
