Volumetric Flask, Clear Glass (Class A)
High-precision analytical glassware manufactured to ISO 1042 standards for exact volume measurement and standard solution preparation.
Precision-Engineered for Analytical Accuracy
The Clear Volumetric Flask (Class A) is a fundamental instrument for quantitative analysis in pharmaceutical, research, and industrial laboratories. Each flask is calibrated "To Contain" (TC, In) at the international reference temperature of 20°C. The narrow neck features a single, permanent graduation mark etched with extreme precision to minimize meniscus reading errors.
At Yash Instrument Company, we prioritize structural integrity and chemical purity. These flasks are manufactured from Type I Borosilicate 3.3 Glass, providing superior resistance to chemical attack and thermal shock, ensuring that the volume remains stable even after repeated sterilization cycles.
ISO 1042 Compliance
Meets the most stringent international accuracy requirements for Class A glassware. Each flask is designed for high-resolution measurement in regulated environments.
Borosilicate 3.3 Glass
Utilizes low-expansion glass with a high resistance to acids, alkalis, and solvents. Fully autoclavable and resistant to thermal stress.
Precision Ground Joint
Equipped with an interchangeable ground neck (NS joint) and a matching glass or PTFE stopper for an airtight and leak-proof seal during mixing.
Manufacturing Features
- Premium Clarity: Optically clear glass for distortion-free meniscus reading.
- Indelible Markings: High-contrast blue or white enamel printing fired into the glass for lifelong visibility.
- Batch Serialization: Each flask is individually checked and stress-relieved in state-of-the-art lehrs.
- Chemical Durability: Superior protection against solvent leaching or protein adsorption.
