Product Overview
This viscosity standard is a certified reference material designed for precise calibration of viscometers and rheometers across a wide temperature range. With defined viscosity values at 20°C (4900 cSt), 25°C (3500 cSt), 37.78°C (1600 cSt), 40°C (1400 cSt), and 50°C (30 cSt), it ensures accurate instrument performance for critical measurements. The fluid is formulated to maintain stability under controlled conditions, minimizing evaporation and degradation over time. Each batch undergoes rigorous testing to meet international standards, providing traceability and reliability for laboratory applications. The 500 ml pack size offers sufficient volume for repeated calibrations without frequent replenishment. Its non-Newtonian behavior is characterized to match real-world fluid dynamics, making it ideal for research, industrial quality control, and regulatory compliance testing. The material is packaged in high-density containers to prevent contamination and preserve integrity during storage and handling.
FAQs
1. What is the shelf life of this viscosity standard?
The product maintains its certified viscosity values for 24 months from the date of manufacture when stored unopened at 15-25°C in its original container.
2. Can this standard be used with capillary viscometers?
Yes, it is compatible with capillary, rotational, and other viscometer types that require certified reference fluids for calibration.
3. Are there lower-viscosity alternatives available?
For applications requiring lower ranges, consider our 10-100 cSt viscosity standards available in similar pack sizes.
4. How should I store this product between uses?
Keep the container tightly sealed in a cool, dry place away from direct sunlight and temperature fluctuations to prevent viscosity drift.
5. Is this standard traceable to national metrology institutes?
Each batch is traceable to NIST or equivalent national standards, with certification documentation provided upon purchase.
