Description

The Erlenmeyer (Conical) Flask with Stopper from Osmosis Scientific is a versatile laboratory glassware item engineered for reliable mixing, solution preparation, reagent storage, and general fluid handling tasks. Manufactured from high-quality Boro 3.3 borosilicate glass, this flask offers exceptional resistance to thermal shock and chemical corrosion, making it ideal for demanding laboratory environments — from research and quality control to educational labs.

Its classic conical shape supports efficient swirling and mixing while minimizing splashes. The narrow mouth enhances control during pouring and helps reduce evaporation, while the included hollow glass stopper provides a secure seal to protect contents from contamination and atmospheric exposure.

White enamel graduations allow for convenient approximate volume reference during everyday workflows. Available in a wide range of capacities — from 100 ml to 2000 ml — this Erlenmeyer flask accommodates small-scale analytical work and larger preparative tasks with ease.

The flat base ensures stable placement on lab benches or stirrers, and the borosilicate construction withstands repeated sterilization cycles, heating, and routine cleaning without compromising performance. Whether used for titration, culture applications, standard solution prep, or reagent containment, this flask combines durability with functional design for everyday laboratory use.
