Cito Autosampler and S-flow IV+ system

The Omnitek Cito Autosampler combined with the S-flow IV+ delivers fully automated, high-precision kinematic viscosity testing for Newtonian fluids including petroleum products, lubricants, and base oils. Designed for industrial automation environments where throughput, consistency, and minimal operator involvement are ongoing priorities, the system handles the full measurement cycle automatically, from sample loading through to results output, without requiring manual intervention between samples.

The system complies with ASTM D7279 and correlates fully with ASTM D445, the internationally recognised standard test method for kinematic viscosity of transparent and opaque liquids. This compliance ensures that results meet the requirements of quality control and research applications where measurement accuracy and traceability to established standards are essential. For laboratories and industrial facilities processing large volumes of petroleum products, lubricants, or base oils on a routine basis, the combination of automation, standard compliance, and repeatable performance makes the Cito Autosampler and S-flow IV+ a reliable and efficient solution for viscosity analysis at scale.

• 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.

The system is well suited to laboratories and production facilities involved in oil analysis, fuel testing, and lubricant development. Its precision and level of automation make it a practical choice across a range of industries including energy, petrochemicals, and automotive manufacturing, as well as research institutions that require efficient and repeatable viscosity testing as part of broader automated analytical workflows. Whether the application is routine quality control on a production line or detailed research into lubricant performance, the Cito Autosampler and S-flow IV+ delivers the accuracy, consistency, and operational efficiency that demanding testing environments require.

The system is operated through multilingual control software accessible via a touchscreen or PC interface, making it straightforward to use across diverse laboratory and industrial settings. Operators can perform calibration, run viscosity index calculations, and manage test sequences directly from the system without requiring specialist software knowledge. Optional advanced PC software extends these capabilities further, allowing a single workstation to control multiple instruments simultaneously, which is a practical advantage for facilities running high-volume testing across several units. Diagnostic alerts notify operators of maintenance requirements, solvent levels, and other operational issues as they arise, supporting consistent uptime and reducing the risk of unplanned interruptions in automated testing environments where continuous operation is a priority.
