R4 RotrOil (Automatic Sample Changer)

Part Number: R4

The R4 RotrOil is an advanced, fully automated version of GNR's RotrOil elemental spectrometer. It integrates an automatic sample carousel (up to 48 cups) and robotic electrode replacement to enable unattended, high-throughput analysis of lubricating oils, fuels, and greases. Ideal for labs processing large volumes daily, the system drastically reduces operator time and consumable costs while delivering ASTM/JOAP-grade oil health data.

                                                
                                                    Automated High-Volume Oil Analysis                                                
                                            
                                                Designed for unattended operation, R4 handles up to 48 samples sequentially, including cup loading, spark analysis, electrode disc changes, and cup removal—streamlining throughput without supervision.
