Description
Erlenmeyer flask with 4 baffles, DURAN® is a baffled culture flask for shaken liquid cultures in microbiology, molecular biology, and cell-culture laboratories. The 250 ml vessel features four internal baffles that promote turbulence and improve gas–liquid mixing during orbital shaking, supporting aerobic growth conditions. A GL45 neck is supplied with diaphragm screw caps for secure closure and controlled access during incubation. DURAN® borosilicate glass construction offers the chemical and thermal robustness expected in routine autoclaving and culture workflows. Pack size is 4 pc(s) with a total weight of 0,980 kg, convenient for parallel cultures and method development. This baffled Erlenmeyer format from manufacturer DWK Life Sciences suits media preparation, seed cultures, and scale-up steps where enhanced aeration matters. The combination of baffles, GL45 interface, and diaphragm screw caps supports reproducible shaking-flask protocols in research and production-support labs without altering standard handling practices.

Questions about Erlenmeyer flask with 4 baffles, DURAN®, 250 ml, GL45, with diaphragm screw caps
What is this article?
Erlenmeyer flask with 4 baffles, DURAN®, 250 ml, GL45, with diaphragm screw caps is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Erlenmeyer flasks, inside Beakers & flasks, in Labware.
An Erlenmeyer, or conical, flask has a flat base and a narrowing wall so a liquid can be swirled. It is the ordinary culture and titration flask. A baffled wall is a different article, used when the swirl must turn the liquid over.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
