Introduction
In the world of scientific research and chemical analysis, even a microscopic error can compromise months of work. When it comes to measuring liquid volumes with absolute precision, the Class A Volumetric Flask is the gold standard. At Amar Enterprises, we understand that accuracy is non-negotiable, which is why our flasks come with the prestigious ISI Mark (IS 915)—a symbol of uncompromising quality and reliability.
Why Choose Class A Over Class B?
Volumetric flasks are generally categorized into two classes based on their accuracy:
- Class A: Designed for analytical and high-precision work. These have significantly lower error tolerances and are calibrated to meet the most stringent laboratory requirements.
- Class B: Intended for general purpose and educational use where extreme precision is less critical.
- The ISI Mark Advantage: An ISI-marked flask (per IS 915:2012) guarantees that the glassware has undergone rigorous testing by the Bureau of Indian Standards (BIS) for durability, thermal resistance, and volume accuracy.
Key Features of Amar Enterprises Volumetric Flasks
- Premium Material: Fabricated from 3.3 Low Expansion Borosilicate Glass, our flasks are highly resistant to chemical attack and thermal shock.
- Expert Calibration: Each flask is individually calibrated at standard temperatures (typically 20°C or 27°C) to ensure the exact volume is delivered.
- BIS Certification (ISI Mark): Our products comply with the IS 915 standard, providing global clients with peace of mind regarding the flask’s build and measurement quality.
- Interchangeable Stoppers: Equipped with high-grade PE or ground-glass stoppers, ensuring a leak-proof and airtight seal for volatile solutions.
- Permanent Markings: High-contrast blue or white enamel markings are fired onto the glass, making them resistant to repeated washing and chemical wear.
Core Applications
- Standard Solution Preparation: Essential for creating solutions with precise molarity.
- Pharmaceutical Testing: Used in QC labs for drug formulation and analysis.
- Quantitative Analysis: Ideal for titrations and volumetric measurements in environmental and forensic labs.
- Education & Research: Vital for advanced university research and industrial R&D.
Care and Maintenance Tips
- Avoid Direct Heat: Never heat a volumetric flask over a direct flame; excessive heat can alter the glass’s shape and ruin its calibration.
- Proper Cleaning: Use specialized lab detergents and soft brushes to avoid scratching the internal surface.
- Rinsing: Always rinse the flask with distilled water before use to ensure no contaminants remain.
