Cito Autosampler for S-flow IV

Part Number: Cito

The Cito Autosampler is a high-speed, modular robotic arm designed to fully automate the sample injection process for the S‑Flow IV+ kinematic viscometer. It seamlessly integrates with existing systems—servicing up to two S‑Flow IV+ units simultaneously (8 tubes total)—and enables unattended operation, enhancing throughput and consistency in viscosity testing .

                                                
                                                    High Throughput & Autonomy                                                
                                            
                                                Processes 25–80 injections per hour (up to 80/hr when both S‑Flow IV+ units are connected), operating completely unattended—even overnight .
