CANNON MANNING ViSCOMETER

Cannon Manning Viscometer Tube (CANNON MANNING)

🧪 Cannon Manning Viscometer Tube

The Cannon Manning Vacuum Viscometer (Reversed Flow) is a highly precise glass laboratory instrument designed for measuring the viscosity of highly viscous liquids, in accordance with ASTM D2171. This viscometer is a key piece of equipment in quality control, research and development, and specialized laboratories within the petroleum, petrochemical, asphalt, and polymer industries.

🔍 Operating Principle and Unique Technology

In conventional viscometers, the fluid sample flows through a glass capillary solely under the force of gravity. However, in reversed-flow vacuum viscometers, a controlled negative pressure (vacuum) is applied to draw the sample through the tube between two timing bulbs.

This technique enables reliable and repeatable measurement of extremely viscous and high-consistency fluids, which cannot be accurately measured using standard gravity-flow viscometers.

🧪 Key Features of the Cannon Manning Viscometer Tube

✔ Complies with ASTM D2171 standard
✔ Reversed flow design with vacuum assistance – enables viscosity measurement at very high ranges and for highly viscous fluids
✔ Low sample volume (minimum 6 mL) – reduces material consumption and waste
✔ Standard bath immersion depth (minimum 180 mm) – compatible with common laboratory temperature baths
✔ Calibration certificate and operating instructions – ensures accuracy, reliability, and traceability of results
✔ Compatible with standard metal holders – stable and easy installation on laboratory baths

📏 Measurement Ranges and Available Sizes

The Cannon Manning vacuum viscometer is available in multiple sizes ranging from No. 4 to No. 14, each suitable for a specific viscosity range.

This variety allows users to select the most appropriate viscometer based on the type and viscosity of the test sample.

🏭 Applications

The Cannon Manning Vacuum Viscometer is widely used for laboratory and industrial viscosity analysis of:

✔ Asphalt and bituminous materials for road construction quality control
✔ Industrial lubricants and heavy oils
✔ Highly viscous and polymer-based fluids
✔ Chemical and resin materials
✔ Formulation analysis and new product development

📊 Advantages

🔹 High accuracy and excellent repeatability – reliable results for standard testing and quality control
🔹 Wide application range – suitable for both moderately viscous and extremely thick materials
🔹 Optimized design for professional laboratories – easy installation, simple maintenance, and compliance with international standards
