Product Overview
This high-precision viscosity standard is engineered to deliver accurate and repeatable calibration for viscometers across a wide temperature range. Certified at 77,000 cSt (20°C), 47,000 cSt (25°C), 13,000 cSt (40°C), and 6,100 cSt (50°C), it ensures traceability to international standards, making it indispensable for labs requiring strict quality control. The liquid formulation is stable, non-volatile, and resistant to thermal degradation, guaranteeing long-term reliability. Each batch undergoes rigorous testing to confirm compliance with ISO guidelines, providing confidence in measurement accuracy. The 500 ml pack size offers sufficient volume for frequent calibrations without frequent replenishment. Designed for seamless integration into existing lab workflows, this viscosity standard minimizes errors in rheological testing, fluid dynamics research, and industrial process monitoring. Its chemical inertness prevents cross-contamination, while the tamper-evident packaging preserves integrity during storage and transport.
FAQs
1. What is the shelf life of this viscosity standard?
When stored in original, unopened packaging at 15-25°C, the standard maintains its certified values for 24 months from the date of manufacture.
2. Can this standard be used with Cannon-Fenske viscometers?
Yes, it is fully compatible with Cannon-Fenske, Ubbelohde, and other capillary viscometers requiring certified reference fluids.
3. How does temperature variation affect the calibration accuracy?
The standard is designed to provide precise measurements at specified temperatures (20°C, 25°C, 40°C, 50°C). Deviations beyond ±0.5°C may require recalibration.
4. Is this viscosity standard traceable to NIST or other metrology institutes?
Each batch is traceable to NIST SRMs or equivalent national metrology standards, with documentation provided in the certificate of analysis.
5. What precautions should be taken during handling to avoid contamination?
Use clean, dry glassware for dispensing. Avoid direct contact with skin or non-inert materials. Reseal the container immediately after use to prevent moisture absorption.
