Why Amber Glass Matters for Class-A Accuracy
A Class-A volumetric flask is already built to a tighter tolerance band than Class-B, and the amber exterior coating on this flask adds a second layer of protection by blocking UV and visible light that can degrade light-sensitive reagents and standard solutions before they are even used. Buyers working with photosensitive titrants, vitamin assays or similar light-sensitive analytical work should specify amber glass for exactly this reason; buyers without a light-sensitivity requirement can use the standard clear-glass equivalent.
Frequently Asked Questions
Why choose an amber volumetric flask over a clear one?
Amber glass blocks UV and visible light that can degrade light-sensitive solutions, which is important for photosensitive reagents and standard solutions.
What tolerance class is this flask?
It is a Class-A tolerance volumetric flask, the tighter of the two standard tolerance classes.
What capacities are available?
Capacities range from 5ml to 2000ml across 11 sizes: 5, 10, 20, 25, 50, 100, 200, 250, 500, 1000 and 2000ml.
