Product Overview
This viscosity standard is a high-precision reference fluid designed for accurate calibration of viscometers and rheometers across a range of temperatures. Certified to strict analytical standards, it provides consistent and reliable viscosity values (790 cSt at 20°C, 580 cSt at 25°C, 280 cSt at 37.78°C, 250 cSt at 40°C, and 160 cSt at 50°C), ensuring traceability and reproducibility in laboratory measurements. The fluid is formulated to minimize evaporation and degradation, maintaining stability over extended use. Its low volatility and resistance to thermal breakdown make it ideal for repeated testing without compromising accuracy. The analytical grade ensures compliance with international standards, making it a trusted choice for research, industrial testing, and quality assurance applications. Each batch undergoes rigorous quality checks to guarantee uniformity and precision, eliminating variability in experimental results. The 500 ml pack size offers sufficient volume for routine calibration while reducing the need for frequent replenishment.
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 (15–25°C). Avoid exposure to direct sunlight or extreme temperatures to prevent degradation.
2. Can this standard be used with capillary viscometers?
Yes, this viscosity standard is compatible with capillary viscometers, rotational viscometers, and other viscosity measurement instruments. Its certified values ensure accurate calibration across different viscometer types, provided the instrument is properly cleaned and maintained.
3. Are there alternatives for lower or higher viscosity ranges?
For viscosities outside this range, alternative standards are available, such as 100 cSt or 1000 cSt fluids. These can be selected based on specific calibration requirements or instrument limitations. Always verify the temperature-viscosity profile to match your application needs.
4. How should this standard be stored to maintain accuracy?
Store the viscosity standard in a cool, dry place away from heat sources and direct sunlight. Keep the container tightly sealed when not in use to prevent contamination or evaporation, which could alter the viscosity values over time.
5. Is this standard traceable to national or international references?
Yes, this viscosity standard is traceable to NIST (National Institute of Standards and Technology) or equivalent international metrology institutions. The certification documentation provided with each batch includes traceability details for compliance and audit purposes.
