Product Overview
The melting point standard set containing vanillin, phenacetin, and caffeine is designed for precise calibration of melting point apparatus in laboratory settings. Each component in this set serves as a reliable reference material, ensuring accurate temperature measurements during experiments. Vanillin, with its well-documented melting point, provides a stable baseline for calibration, while phenacetin and caffeine offer additional reference points for broader temperature range validation. These standards are manufactured under strict quality control to maintain consistent purity and performance, eliminating variability that could affect experimental results. The analytical-grade purity guarantees minimal impurities, making them ideal for sensitive applications where precision is critical. Packaged in a convenient 3 g set (1 g each), this combination covers a practical range of melting points, allowing users to verify instrument accuracy across different temperature thresholds. The solid form (powder or crystals) ensures ease of handling and long-term stability under proper storage conditions. Whether used in routine calibration or quality assurance protocols, this set delivers dependable results, reducing the risk of errors in melting point determinations.
FAQs
1. What is the melting point range covered by this standard set?
Vanillin melts at approximately 81-83°C, phenacetin at 134-136°C, and caffeine at 234-236°C, covering a broad calibration range.
2. Can these standards be reused after initial calibration?
Yes, if stored properly in a dry, airtight container away from moisture and contaminants, they can be reused multiple times.
3. Are these standards compatible with digital melting point apparatus?
Absolutely, they are designed for use with both manual and digital melting point instruments for consistent results.
4. How should these standards be stored for long-term stability?
Store in a cool, dry place in tightly sealed containers to prevent degradation from humidity or oxidation.
5. What alternatives exist if I need a different melting point range?
Consider benzoic acid (122°C) or urea (133°C) for lower ranges, or acetanilide (114°C) for additional reference points.
