Description
The Amber Graduated Erlenmeyer Conical Flask – Narrow Mouth from Osmosis Scientific is a versatile laboratory essential designed for mixing, titration, culturing, solution preparation, and chemical handling. Crafted from premium borosilicate 3.3 glass, this conical flask offers excellent chemical resistance and thermal stability, making it suitable for rigorous daily use in research labs, quality control environments, and educational settings.
The narrow mouth design improves safety during mixing by reducing splashing and facilitating the use of corks or stoppers when needed. The amber tint of the glass provides protection against harmful UV and visible light, making this flask ideal for storing or processing light-sensitive solutions and reagents. Accurate white enamel graduations allow for quick volume estimation, enhancing convenience and workflow efficiency during routine lab tasks.
Available in practical laboratory sizes ranging from 100 ml to 1000 ml — this flask accommodates lab needs from small preparative work to larger solution batches. Its robust borosilicate construction tolerates repeated sterilization and cleaning cycles, with thermal shock resistance that supports safe use on hot plates and during gentle heating.

Frequently Asked Questions (FAQs)
This flask is used for mixing, heating, and approximate volume measurement of light‑sensitive solutions such as photosensitive reagents, buffers, and culture media.
A narrow mouth refers to the reduced neck diameter at the top of the flask, which reduces evaporation and splashing while allowing the use of standard stoppers or closures.
Graduations are designed for approximate volume indication; for precise volumetric measurements you should use Class A volumetric flasks or cylinders.
Typical sizes include 100 mL, 150 mL, 250 mL, 500 mL, and 1000 mL, covering most routine lab mixing and culture volumes.
