Product Overview

This viscosity standard is a certified reference material designed to deliver precise and reliable viscosity measurements across a range of temperatures. With defined kinematic viscosity values—19000 cSt at 20°C, 12000 cSt at 25°C, 4000 cSt at 37.78°C, 3400 cSt at 40°C, and 1700 cSt at 50°C—it serves as an essential tool for calibrating viscometers and validating instrument performance. The fluid is formulated to maintain stability and consistency, ensuring accurate and repeatable results in laboratory environments. Its high-grade certification guarantees traceability to international standards, making it suitable for quality control, research, and industrial applications where precision is critical. The 500 ml pack size provides an optimal balance between usability and shelf life, minimizing waste while offering sufficient volume for repeated calibrations. The liquid form ensures ease of handling and compatibility with most viscometer models, reducing the risk of contamination or measurement errors.
