Product Overview
This viscosity standard is a high-precision reference fluid designed for calibrating viscometers and ensuring accurate viscosity measurements across a range of temperatures. The fluid provides certified kinematic viscosity values (in centistokes, cSt) at 20°C (28000 cSt), 25°C (17000 cSt), 37.78°C (6000 cSt), 40°C (5100 cSt), and 50°C (2500 cSt), making it suitable for laboratories requiring strict adherence to measurement standards. The fluid is formulated to maintain stability over time, minimizing evaporation and degradation, which ensures long-term reliability in calibration processes. Its consistency and traceability to international standards make it an essential tool for quality assurance in industries such as pharmaceuticals, petrochemicals, and materials science. The 500 ml pack size offers sufficient volume for repeated calibrations without frequent replenishment. This product is ideal for researchers, technicians, and educators who demand precision in their viscosity testing protocols.
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 sealed container at room temperature.
2. Can this standard be used for both capillary and rotational viscometers?
Yes, the fluid is compatible with most viscometer types, including capillary, rotational, and falling-ball viscometers, provided the instrument’s operating range aligns with the fluid’s viscosity values.
3. Are there any special storage conditions required?
Store the bottle upright in a cool, dry place away from direct sunlight and heat sources. Avoid freezing or exposure to temperatures above 50°C to prevent degradation.
4. How do I verify the accuracy of this standard?
The product comes with a certificate of analysis detailing its traceability to NIST or equivalent standards. Cross-checking with a secondary certified standard can further validate its accuracy.
5. Is this viscosity standard suitable for high-temperature applications?
The fluid is stable up to 50°C, as indicated by its certified viscosity at that temperature. For applications exceeding this range, consider a high-temperature viscosity standard.
