Product Name – Viscosity Standard (cSt)
Quantity/Pack Size – 500 ml
Form – Liquid
Grade – Certified Reference Material (CRM)
Application – Viscometer calibration, quality assurance, instrument validation
Product Overview
This high-precision viscosity standard (cSt) is designed for accurate calibration of viscometers and rheometers in laboratory settings. The standard provides certified viscosity values at multiple temperatures—43 cSt at 20°C, 34 cSt at 25°C, 20 cSt at 37.78°C, 18 cSt at 40°C, and 13 cSt at 50°C—ensuring reliable performance across a wide range of testing conditions. Formulated as a stable, homogeneous liquid, it adheres to strict quality control measures, making it a trusted reference material for instrument validation and quality assurance protocols. The 500 ml pack size offers sufficient volume for repeated use, reducing the need for frequent replenishment. Compatible with most capillary, rotational, and falling-ball viscometers, this standard is an essential tool for laboratories requiring traceable and reproducible viscosity measurements. Its long shelf life and resistance to degradation ensure consistent accuracy over extended periods, provided proper storage conditions are maintained.
FAQs
1. What is the shelf life of this viscosity standard?
The viscosity standard remains stable for up to 24 months from the date of manufacture when stored in its original, tightly sealed container at room temperature, away from direct sunlight and moisture.
2. Can this standard be used with digital viscometers?
Yes, this viscosity standard is compatible with digital viscometers, including capillary, rotational, and automated systems, provided the instrument is calibrated to the specified temperature ranges.
3. Are there alternatives for lower viscosity ranges?
For applications requiring lower viscosity values, consider standards calibrated below 10 cSt, such as water-based or silicone-based reference fluids, which are available in smaller increments.
4. How should I store this viscosity standard to maintain accuracy?
Store the bottle upright in a cool, dry place (15–25°C) with the cap tightly sealed. Avoid exposure to temperature fluctuations or contaminants, as these can alter the viscosity properties over time.
5. Is this standard traceable to national or international reference materials?
This viscosity standard is manufactured and certified in accordance with ISO 17034 and is traceable to NIST (National Institute of Standards and Technology) reference materials for viscosity measurements.
