Viscosity Testing

Viscosity is a measure of a fluid’s internal resistance to flow or deformation. Fluids with high viscosity—such as oils, gels, or honey—flow slowly because their molecular structure creates greater internal friction. In contrast, low-viscosity fluids like water or alcohol flow easily due to minimal molecular interaction. In simple terms, viscosity describes how “thick” or “thin” a fluid is.

Accurate viscosity data is essential for manufacturers, as it helps predict how a product will behave during processing, packaging, and end-use. Whether optimizing pumpability, ensuring proper spreadability, or meeting regulatory or performance specifications, controlling viscosity is critical to product consistency and quality. Most formulations are adjusted to achieve a specific viscosity profile that aligns with their intended application.

At A.S. Chemical Laboratories Inc., we use advanced, high-precision viscometers to measure the viscosity of liquids across a wide range of industries, including construction materials, food and beverages, cosmetics and personal care products, pharmaceutical formulations, research samples, and health-related products. Our equipment accommodates both low- and high-viscosity materials and provides accurate, reproducible results.

Whether you need routine viscosity testing, formulation comparison, or custom analysis tailored to your product’s performance requirements, our laboratory is equipped to deliver reliable and consistent measurements.
