Erlenmeyer flask
Hot vapour condenses on the upper section of the Erlenmeyer flask, reducing solvent loss.Erlenmeyer flasks used in cell culture are sterilized and may feature vented closures to enhance gas exchange during incubation and shaking.The oxygen transfer rate in Erlenmeyer flasks depends on the agitation speed, the liquid volume, and the shake-flask design.Main factor for out-of-phase operation is the viscosity of the culture medium, but also the vessel diameter, low filling levels and/or a high number of baffles.[11][12][13] To impede illicit drug manufacturers, the state of Texas previously restricted the sale of Erlenmeyer flasks to those who have the requisite permits.
