Amber Volumetric Flask, Class-A, Batch Certificate, ISO

The Amber Volumetric Flask, Class-A, Batch Certificate, ISO is designed for analytical procedures involving light-sensitive compounds. Many chemical reagents, pharmaceutical active ingredients, vitamins, and organic standards undergo photochemical breakdown when exposed to ambient light or ultraviolet radiation. This amber glass volumetric flask provides an effective barrier against light transmission, safeguarding sample integrity throughout measurement and preparation steps.

Crafted from premium BORO 3.3 borosilicate glass, the flask combines chemical resistance with high mechanical strength. The rich, uniform amber layer on the outer glass surface blocks harmful UV light wavelengths while maintaining clarity on the inside to allow clear visual observation of liquid levels and meniscus alignment.

Every flask is manufactured according to ISO Class-A volumetric guidelines, ensuring tight volumetric tolerances required for stringent analytical assays. The calibration is established based on the poured-in volume (“In”), assuring accurate volume containment at standard reference temperatures. A single, high-contrast graduation mark etched into the neck facilitates exact volume adjustment.

The flask features a ground glass joint engineered to accept standard stoppers, establishing an airtight and leak-proof closure. This prevents evaporation, sample loss, and environmental contamination during solution homogenization by inversion. Accompanied by batch work certification, each production lot meets complete traceability and regulatory documentation needs for accredited testing facilities.

Edulabs supplies this amber volumetric flask as a dependable solution for analytical laboratories demanding high precision combined with protection for sensitive light-reactive media.
