For most solutions this is inconsequential — but for photosensitive compounds, the light exposure during solution preparation and short-term storage is enough to cause measurable degradation. Phenolphthalein indicator solutions, silver nitrate standards, certain drug compounds, dye-based assays, and photolabile chelates all require amber glass protection during the volumetric preparation step itself, not just during final storage. The SIBATA 2307A Series Amber Volumetric Flask is manufactured from low-actinic amber borosilicate glass that blocks the wavelengths responsible for photodegradation while maintaining the full ASTM E-288 Class A accuracy and USP compliance required for quantitative analytical work. The standard taper glass stopper provides a leakproof, solvent-compatible seal. This is the same flask as the 2306A Series in every measurable analytical respect — the amber glass is the only difference, and that difference matters when your analyte is light-sensitive.\u003c\/p\u003e\u003ch2 class=\"mb-2 mt-4 font-display font-semimedium text-base first:mt-0 md:text-lg [hr+\u0026amp;]:mt-4\"\u003eFeatures and Benefits\u003c\/h2\u003e\u003cul class=\"marker:text-quiet list-disc\"\u003e\n\u003cli class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [\u0026amp;\u0026gt;p]:pt-0 [\u0026amp;\u0026gt;p]:mb-2 [\u0026amp;\u0026gt;p]:my-0\"\u003e\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003e\u003cstrong\u003eLow-actinic amber glass blocks photodegradation-causing wavelengths:\u003c\/strong\u003e The 2307A Series is manufactured from low-actinic amber borosilicate glass — the same glass type used in amber reagent bottles and pharmaceutical vials for light-sensitive products.

The glass stopper and amber borosilicate body provide both chemical inertness and light protection for extended storage — this combination is the reason amber volumetric flasks are the preferred container for light-sensitive reference standards that need to be prepared once and used over several weeks. For very long-term storage (months), transfer the solution to an amber reagent bottle with a tightly sealed cap — the volumetric flask stopper seal is reliable but not hermetic enough for multi-month storage of volatile or hygroscopic solutions. Pack quantities: 10mL and 25mL in packs of 6, 50mL through 250mL in packs of 4, 500mL and 1000mL in packs of 2.

Amber glass provides continuous passive protection without any handling overhead, and the protection is uniform across the entire flask surface rather than depending on wrapping integrity. For regulated environments, amber glass is also easier to document in SOPs and audit logs.\u003c\/p\u003e\u003ch2 class=\"mb-2 mt-4 font-display font-semimedium text-base first:mt-0 md:text-lg [hr+\u0026amp;]:mt-4\"\u003eQuality Assurance\u003c\/h2\u003e\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eSIBATA Scientific Technology has manufactured precision analytical glassware since 1932.
