Amber Volumetric Flask, Class A
Premium UV-protective glassware calibrated to Class A standards for the most demanding light-sensitive analytical applications.
Maximum Protection for Photosensitive Reagents
The Amber Volumetric Flask (Class A) is specifically engineered for laboratory professionals who require absolute precision while handling light-sensitive chemicals. The deep amber color is fused into the Borosilicate 3.3 glass, creating a permanent barrier that filters out harmful UV radiation and short-wave visible light.
Calibrated "To Contain" (TC, In) at a reference temperature of 20°C, these flasks feature a single, high-contrast graduation mark etched into the narrow neck. This design provides maximum sensitivity for exact volume adjustment, ensuring your standard solutions remain stable and accurate.
UV-Shielding Glass
The permanent amber stain penetrates the glass surface, ensuring light protection for chemicals like Silver Nitrate or Potassium Permanganate without leaching or fading.
Class A Precision
Fully compliant with ISO 1042 accuracy requirements. Every flask is individually calibrated and stress-relieved to maintain dimensional stability over its lifespan.
Interchangeable Joint
Features a precision-ground interchangeable neck compatible with standard glass or PTFE stoppers for a vacuum-tight, leak-proof seal during mixing.
Manufacturing Features
- Borosilicate 3.3 Material: Superior chemical durability and low coefficient of expansion.
- High-Contrast Printing: White enamel graduations for excellent visibility against the amber glass.
- Calibrated at 20°C: Standard analytical reference temperature for reliable concentration preparation.
- Thermal Stability: Resistant to temperature variations; suitable for laboratory sterilization cycles.
