Description
Erlenmeyer flask, 5000 ml, GL 45, with screw cap and 4 baffles is a large-capacity culture vessel designed for laboratory mixing and aeration applications. Manufactured from borosilicate glass 3.3, it offers the thermal and chemical resistance required for repeated autoclaving and everyday lab use. The flask features a GL 45 thread and is supplied with a PBT screw cap fitted with a PTFE-coated seal rated up to +200 °C. Four integrated baffles promote efficient mixing and gas exchange during shaking culture work. When autoclaving, the screw cap must be placed loosely and must not be tightened. With a nominal volume of 5 l and a net weight of 1,400 kg, this Rettberg culture flask is well suited for fermentation, cell culture scale-up and general media preparation. The combination of robust glass construction, secure GL 45 closure and baffle geometry supports reproducible results in microbiology, biotechnology and pharmaceutical research environments.

Questions about Erlenmeyer flask, 5000 ml, GL 45, with screw cap and 4 baffles
What is this article?
Erlenmeyer flask, 5000 ml, GL 45, with screw cap and 4 baffles is the article on this page. Luminix Health distributes Rettberg 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.
