Product Overview
This density standard (0.8168 g/ml at 15°C) is a high-precision reference liquid designed for calibrating densitometers, hydrometers, and other density-measuring instruments. Formulated with ultra-pure solvents and stabilized additives, it ensures long-term accuracy and repeatability in laboratory environments. The standard is traceable to NIST (National Institute of Standards and Technology) or equivalent international standards, guaranteeing reliability for critical measurements. Its low thermal expansion coefficient minimizes temperature-induced errors, while the sealed packaging prevents contamination and evaporation. Ideal for quality control, research, and educational labs, this standard maintains consistency across multiple tests. The 100 ml pack size offers sufficient volume for repeated calibrations without frequent replacements. Store in a cool, dry place away from direct sunlight to preserve integrity. Compatible with most glass and plastic labware, but avoid reactive metals. For best results, allow the standard to equilibrate to room temperature before use.
FAQs
1. What is the shelf life of this density standard?
When stored unopened in recommended conditions, the shelf life is typically 24 months from the date of manufacture. Check the label for batch-specific expiry.
2. Can this standard be used with digital densitometers?
Yes, it is compatible with both analog hydrometers and digital densitometers, provided the instrument’s measurement range includes 0.8168 g/ml.
3. How should I dispose of expired or unused density standard?
Follow local chemical waste disposal regulations. Small quantities can often be neutralized or incinerated, but consult your institution’s safety guidelines.
4. Does temperature affect the accuracy of this standard?
The standard is certified at 15°C. For precise results, use it at this temperature or apply correction factors if measurements are taken at other temperatures.
5. Is this standard suitable for calibrating alcohol meters?
Yes, it can be used for alcohol meters if the density range matches, but verify compatibility with the meter’s specifications for optimal accuracy.
