Erlenmeyer flask culture is a process that is widely used in microbiology, biotechnology, and pharmaceutical laboratories. Erlenmeyer flasks for culturing are distinguished by their versatility, making them an ideal choice for conducting research on a wide variety of microorganisms and cells. In this article, we will show you how to properly prepare and cultivate cultures in these flasks for optimal results.
Why are Erlenmeyer flasks the ideal choice?
Erlenmeyer flasks for culturing cultures are laboratory vessels with a characteristic conical shape that provide effective gas exchange and mixing of cultures. The wide opening at the top of the flask allows for easy addition of ingredients, sampling and ensuring adequate air access. For example, when cultivating aerobic bacteria such as Escherichia coli, adequate air access allows for effective aeration of the culture, which translates into faster cell growth and higher productivity in scientific research or biotechnological production. Their design allows for use in both static cultures and dynamic systems, such as incubators with orbital mixing.
To fully utilize the potential of Erlenmeyer flasks, their capacity should be appropriately matched to the volume of the culture medium and the type of culture. For example, aerobic microorganism cultures require maintaining an appropriate ratio of the volume of the medium to the total capacity of the flask (usually around 30-40%), which allows for effective aeration. It is also worth mentioning that the use of flasks made of appropriate materials, such as borosilicate glass, ensures resistance to temperature changes and chemicals.

Preparation of Erlenmeyer flasks for culturing cultures
Proper preparation of flasks before beginning culturing is essential for obtaining reproducible results. The preparation process begins with thorough cleaning. Flasks should be washed in warm water with a mild laboratory detergent, such as neutral pH detergents or detergents designed specifically for laboratory equipment that do not leave residues or react with materials. They should then be rinsed thoroughly with distilled or deionized water to ensure complete removal of detergent residues and to avoid potential chemical contamination. After washing, the flasks should be sterilized, which is usually done by autoclaving. Sterilization is essential to remove any potential microbial contamination that could affect culturing results.
For cell cultures, consider using flasks with vented stoppers or special lids that provide adequate airflow while minimizing the risk of contamination. It is also worth preparing a suitable connection to an orbital mixer if the flasks will be used in dynamic culture systems.

Cultivation in Erlenmeyer flasks
When cultivating cultures in Erlenmeyer flasks, it is crucial to maintain the appropriate environmental conditions. The most important factors include:
- Temperature – It should be adjusted to the requirements of the organism being grown. Most bacteria require a temperature in the range of 30-37 °C, while yeasts often prefer slightly lower temperatures, e.g. 25-30 °C.
- Mixing – Dynamic cultures require the use of orbital mixing, which ensures even distribution of nutrients and effective aeration.
- Sterility – Each stage of cultivation should be carried out under sterile conditions to avoid contamination.
- pH control – Some cultures require a very specific pH of the medium. Regular checking and possible correction is essential.
Erlenmeyer flasks are a universal tool that allows for the cultivation of various types of cultures, from microorganisms to animal cells. For example, aerobic bacteria such as Escherichia coli thrive in dynamic cultures in Erlenmeyer flasks, where adequate gas exchange and orbital mixing support their growth. Similarly, mammalian cells such as CHO (Chinese Hamster Ovary) cell lines can be efficiently cultivated in these flasks, provided that the appropriate culture medium and incubation conditions are provided. Their practicality and efficiency make them indispensable in laboratories around the world.
