Product Overview
This range of viscosity standards (cSt) is engineered for precise calibration of rotational, capillary, and other viscometers across varying temperatures. Each standard is formulated to deliver consistent kinematic viscosity values—14 cSt at 20°C, 12 cSt at 25°C, 8 cSt at 37.78°C, 7.5 cSt at 40°C, and 5.8 cSt at 50°C—ensuring accuracy in laboratory measurements. The standards are produced under stringent quality controls, with NIST-traceable certification to guarantee reliability for research, industrial testing, and quality assurance applications. The 500 ml pack size provides an optimal balance between volume and shelf stability, minimizing contamination risks while reducing frequent replenishment needs. The liquid form ensures homogeneous distribution and ease of handling, while the analytical grade confirms low impurity levels for interference-free results. Compatible with most viscometer models, these standards eliminate variability in testing protocols, supporting reproducible data across experiments. Storage in tightly sealed containers under controlled temperatures preserves integrity, extending usability without degradation.
FAQs
1. What is the shelf life of these viscosity standards when stored properly?
When stored in original, unopened containers at 15–25°C away from direct sunlight, these standards retain their certified viscosity values for up to 24 months from the date of manufacture.
2. Can these standards be used with both digital and analog viscometers?
Yes, the standards are compatible with all viscometer types, including rotational, capillary, and falling-ball models, provided the instrument is designed for kinematic viscosity measurements within the specified cSt range.
3. Are these standards suitable for high-temperature applications beyond 50°C?
The provided standards are certified up to 50°C. For temperatures exceeding this, specialized high-temperature viscosity standards should be used to ensure accuracy, as thermal degradation may alter viscosity.
4. How do I verify the traceability of these standards?
Each batch includes a certificate of analysis (CoA) with NIST-traceable reference data, lot-specific viscosity values, and expiration details. Cross-check the CoA with your viscometer readings for validation.
5. What precautions should be taken to avoid contamination during use?
Use clean, dedicated pipettes or dispensers for each standard to prevent cross-contamination. Reseal the container immediately after use and avoid exposing the liquid to airborne particulates or moisture.
