CANNON Product

Automatic Viscometer

ASTM D445 Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (the Calculation of Dynamic Viscosity)

The CAV 5 family has every lab covered, delivering routine high-throughput testing with the CAV-D Dual, scalable flexibility with the CAV-D, adaptable configurations with the CAV-X, and maximum capability for the most demanding applications with the CAV-R.

One Platform. Any Sample. Total Control.
Only the revolutionary CAV™ 5 Family from Cannon delivers a viscosity platform that provides exceptional capability, reliability and control.

One Platform
The CAV5 represents the culmination of three proven instrument generations: CAV 2100, MiniAV and CAV 4. This union brings our most trusted capabilities together and enhances them in a single platform. Built on decades of proven performance and engineering experience, CAV 5 delivers the highest level of capability Cannon has ever offered, now in the most compact design yet.

Any Sample
CAV 5 delivers a wider operating range allowing more samples to run smoothly with less adjustment and greater confidence. It’s designed to perform consistently across the full spectrum of sample types, from routine to highly challenging materials. Total Control Total Control is delivered through Sync Anywhere powered by FlowHub,™ a next-generation intuitive user interface and flexible standalone architecture. Together, these capabilities allow approved methods to be deployed centrally and for tests to be executed locally. All while results can be collected across labs, campuses or multiple sites. Combined with the CAV 5 single-bath architecture, which removes the constraints of traditional multi-bath systems, labs gain greater freedom in layout design.


CAV5	Features & Benefits Efficient Handling of Highly Viscous Samples – Automated Tray Heat pre-heats samples to optimal test conditions, ensuring smooth handling and reliable analysis even for very viscous materials. Protected Sample Integrity – TargetHeat™ selectively heats only the samples that require conditioning, preventing overheating and preserving sample stability for accurate, repeatable results. Higher Throughput with Less Solvent Use – WashPort™ cleans the tube tip without pulling the full sample into the viscometer, reducing solvent consumption while improving workflow efficiency and sample retention. Reduced Consumable Costs – Vial Wash automatically cleans vials for safe reuse and proper waste management, minimizing consumable usage and ensuring hazardous residues are handled correctly. Faster Method Setup – Start Optimization automatically determines the ideal thermal soak and sample draw parameters for each sample type and saves them for future runs, improving throughput and consistency. Improved Data Quality – Run True monitors for artifacts such as bubbles or sample sag in real time and automatically corrects them, ensuring reliable and traceable test results. Optimized Cleaning performance – CleanBoost™ allows users to create customized cleaning recipes with precise solvent control, reducing solvent use while ensuring complete residue removal. Flexible Cleaning Options – Three-solvent capability enables operators to select the most effective solvent combination for different sample types, improving cleaning efficiency and test reliability. Reliable Operation with Difficult Samples – Heated waste lines prevent clogging by keeping waste flowing freely, enabling uninterrupted operation even with high-viscosity or solidifying materials. Note: Features may vary depending on the selected model and configuration.
