Erlenmeyer Flask made of Borosilicate Glass 3.3 with Reinforced Rim

The Erlenmeyer flask made of borosilicate glass 3.3 is an indispensable laboratory vessel for professional applications in chemistry, biology and analytical work. With its characteristic conical shape and reinforced rim, it is ideal for shaking, stirring and cultivation work. Available as narrow-neck and wide-neck versions in various volumes from 25 ml to 5000 ml.

Borosilicate glass 3.3 is characterized by excellent thermal stability, low thermal expansion and high chemical resistance. The material is suitable for use at elevated temperatures and withstands most chemicals as well as sudden temperature changes.

The conical shape enables efficient mixing and shaking of liquids, while the flat bottom ensures a secure stand on work surfaces, hot plates and magnetic stirrers. The reinforced rim guarantees increased breakage resistance and facilitates handling in daily laboratory use.

Narrow Neck Design:
Ideal for cultivation work, fermentations and shake cultures. The narrow neck minimizes evaporation and enables the use of standard closures such as cotton plugs, foam caps or aluminum foil.

Wide Neck Design:
Perfect for easy filling, emptying and cleaning. The wide opening facilitates access for stirrer shafts, sensors and sampling tools.
