Product Overview

This viscosity standard (cSt) is a precision-formulated liquid designed for calibrating viscometers and verifying instrument accuracy across multiple temperature points. The standard provides certified kinematic viscosity values at 20°C (88 cSt), 25°C (66 cSt), 37.78°C (35 cSt), 40°C (32 cSt), and 50°C (21 cSt), ensuring reliable performance in temperature-sensitive applications. Manufactured under strict quality controls, it adheres to ISO standards for repeatability and traceability, making it suitable for laboratories requiring high-precision measurements. The non-volatile composition minimizes evaporation, maintaining stability over extended use. Each batch undergoes rigorous testing to confirm viscosity consistency, eliminating variability in test results. The 500 ml pack size offers an optimal balance between usability and shelf life, reducing the need for frequent replacements while ensuring freshness. Compatible with capillary, rotational, and automated viscometers, this standard is an essential reference material for quality assurance protocols in research, industrial, and educational settings where viscosity control is critical.

FAQs

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

The shelf life is 24 months from the date of manufacture when stored unopened in original packaging at 15–25°C, away from direct sunlight and moisture.

2. Can this standard be used with digital and analog viscometers?

Yes, it is compatible with both digital and analog viscometers, including capillary, rotational, and automated systems, provided the instrument is calibrated for kinematic viscosity measurements.

3. How should I store the viscosity standard after opening?

After opening, reseal the container tightly and store it upright in a cool, dry place (15–25°C). Avoid exposure to temperature fluctuations or contaminants to preserve accuracy.

4. Is this standard traceable to NIST or other metrology institutes?

The viscosity values are certified against primary reference materials traceable to international standards, ensuring metrological reliability for calibration purposes.

5. Are there alternatives for lower or higher viscosity ranges?

For viscosities outside this range, consider standards with values such as 5 cSt (low) or 1000 cSt (high), depending on your instrument’s measurement capabilities and application requirements.
