Cito Autosampler and S-flow IV+ system

The Omnitek Cito Autosampler and S-flow IV+ system deliver fully automated, high-precision viscosity testing for Newtonian fluids, including petroleum products, lubricants and base oils. Designed for industrial automation environments, the system minimises operator involvement, increases throughput and ensures consistent, repeatable results. With compliance to ASTM D7279 and full correlation to ASTM D445, it provides reliable, laboratory-grade analysis for quality control and research applications.

• Automatic sample injection for hands-free operation.
• Dual-bath design for simultaneous testing at two temperatures.
• High throughput of up to 80 samples per hour per bath.
• Minimal sample (0.3–1.0 ml) and solvent (2–3 ml) consumption.
• Exceptional temperature stability of ±0.02°C.
• Modular, upgradeable autosampler for future expansion.
• Integrated viscosity index calculation and automated cleaning.
• Profibus and Profinet connectivity options for seamless process integration.

Ideal for laboratories and production facilities involved in oil analysis, fuel testing and lubricant development. The system’s precision and automation make it suitable for industries such as energy, petrochemicals, automotive manufacturing and research institutions seeking efficient, repeatable testing within automated workflows.

Multilingual control software enables complete system management via a touchscreen or PC interface. Operators can perform calibration, run viscosity index calculations and manage test sequences directly from the system or through optional advanced PC software, which allows control of multiple instruments. Diagnostic alerts notify users of maintenance needs, solvent levels or other operational issues, ensuring reliability and uptime in automated environments.
