Product Overview

This viscosity standard is a precision-formulated liquid designed for accurate calibration of viscometers and rheometers across multiple temperature points. Certified to deliver consistent kinematic viscosity values of 0.47 cSt at 20°C, 0.45 cSt at 25°C, 0.41 cSt at 37.78°C, and 0.4 cSt at 40°C, it ensures reliable performance in laboratory settings. The analytical-grade formulation adheres to strict quality control measures, providing traceable and reproducible results for critical applications. Its stability and low evaporation rate make it ideal for long-term use in research, industrial testing, and quality assurance protocols. The 500 ml pack size offers sufficient volume for repeated calibrations without frequent replenishment. Compatible with most standard viscometer models, this standard eliminates variability in measurements, supporting compliance with ISO, ASTM, and other regulatory benchmarks. The solution is packaged in a chemically resistant container to prevent contamination and degradation, maintaining its integrity throughout its shelf life.

FAQs

1. What is the shelf life of this viscosity standard?

The viscosity standard remains stable for 24 months from the date of manufacture when stored unopened in its original container at room temperature, away from direct sunlight and moisture.

2. Can this standard be used with capillary viscometers?

Yes, this viscosity standard is compatible with capillary viscometers, including Cannon-Fenske, Ubbelohde, and Ostwald types, provided the instrument is clean and properly calibrated.

3. Are there alternatives for higher viscosity ranges?

For higher viscosity requirements, consider standards with values such as 10 cSt, 100 cSt, or 1000 cSt, which are available for calibration across broader ranges.

4. How should this standard be stored after opening?

After opening, reseal the container tightly and store it upright in a cool, dry place. Avoid exposure to temperature fluctuations to prevent condensation or evaporation.

5. Is this standard traceable to national or international references?

Yes, the viscosity values are traceable to NIST (National Institute of Standards and Technology) or equivalent international standards, ensuring accuracy and compliance with global metrological requirements.
