Product Information

Avantor carries a broad range of trusted products to help you meet the needs of your lab applications and protocols. Our product offerings can help with biomedical research, forensic work, and clinical diagnostics. Conical flask uses within the laboratory are numerous and varied. Beaker chemistry is an integral element of testing and manufacture within the field of medical science and many other sectors. So ubiquitous are they, that a scientist without a conical flask is like a carpenter without a saw. Flasks are produced in different materials and in different sizes, dependent on the function they are required to fulfil. They are often used in conjunction with probes and sensors in the testing of liquid chemicals. Like beakers, Erlenmeyer flasks are not normally suitable for accurate volumetric measurements. Their stamped volumes are approximate within about 5% accuracy. [8] In biology [ edit ] Microcystis floating colonies in an Erlenmeyer flask.

International standards are reviewed every five years, with this standard reviewed and confirmed in 2020. Conical flasks are one of the larger containers used in a laboratory environment and are often used to mix or boil larger amounts of chemicals. Their design means that swirling a liquid inside to agitate or mix won't lead to a spill which maintains the controlled principles of a laboratory setting. The production of paints, inks, and dyes in industrial settings relies on accurate measurements of electrochemical properties in the product, as well as pH levels, conductivity, and more.

Test tubes have their place in the laboratory and are very useful. However, when a chemical reaction is expected to be larger than the capacity of a test tube, or two chemicals need to be mixed thoroughly, a conical flask is the ideal piece of equipment for the job. Erlenmeyer flasks are also used in microbiology for the preparation of microbial cultures. Erlenmeyer flasks used in cell culture are sterilized and may feature vented closures to enhance gas exchange during incubation and shaking. The use of minimal liquid volumes, typically no more than one fifth of the total flask volume, and baffles molded into the flask's internal surface both serve to maximize gas transfer and promote chaotic mixing when the flasks are orbitally shaken. The oxygen transfer rate in Erlenmeyer flasks depends on the agitation speed, the liquid volume, and the shake-flask design. [9] The shaking frequency has the most significant impact on oxygen transfer. [10]

Oxygenation and mixing of liquid cultures further depend on rotation of the liquid "in-phase", meaning the synchronous movement of the liquid with the shaker table. Under certain conditions the shaking process leads to a breakdown of liquid motion – called "out-of-phase phenomenon". This phenomenon has been intensively characterized for shake flask bioreactors. Out-of-phase conditions are associated with a strong decrease in mixing performance, oxygen transfer, and power input. 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.
