Product Overview
This high-precision viscosity standard is engineered to deliver accurate and repeatable viscosity measurements across a range of temperatures, ensuring reliable calibration for laboratory viscometers. The standard is certified with traceable reference values—59 cSt at 20°C, 47 cSt at 25°C, 27 cSt at 37.78°C, 25 cSt at 40°C, and 18 cSt at 50°C—making it indispensable for applications requiring strict viscosity control. Formulated with high-purity materials, it minimizes batch-to-batch variability, providing consistent performance for critical testing protocols. The liquid form ensures ease of handling and compatibility with most viscometer systems, while its stability under controlled conditions guarantees long-term reliability. Whether used in routine quality assurance or specialized research, this viscosity standard adheres to international metrological standards, offering confidence in measurement accuracy. The 500 ml pack size balances practicality with cost-efficiency, reducing the need for frequent replenishment without compromising on precision. Designed for laboratories demanding traceability and compliance, this standard supports seamless integration into existing workflows, eliminating the guesswork from viscosity-related processes.
FAQs
1. What is the shelf life of this viscosity standard under ideal storage conditions?
The viscosity standard remains stable for up to 24 months when stored in its original sealed container at room temperature, away from direct sunlight and moisture. Always check the certificate of analysis for the exact expiration date.
2. Can this standard be used with capillary viscometers and rotational viscometers?
Yes, the standard is compatible with both capillary (Ostwald, Cannon-Fenske) and rotational viscometers, provided the instrument is calibrated to the specified temperature ranges. Ensure the viscometer is clean and properly zeroed before use.
3. Are there lower or higher viscosity alternatives available for extreme calibration needs?
For viscosities outside this range, alternative standards are available, such as 10 cSt for low-viscosity applications or 1000 cSt for high-viscosity requirements. Contact the supplier for customized solutions if needed.
4. How should this standard be stored to prevent contamination or degradation?
Store the bottle upright in a cool, dry place with the cap tightly sealed. Avoid exposure to temperature fluctuations or volatile chemicals, as these can alter the standard’s properties over time.
5. Is this viscosity standard traceable to national or international reference materials?
Yes, the standard is traceable to NIST (National Institute of Standards and Technology) or equivalent international bodies, with certification documentation provided for audit and compliance purposes.
