The Erlenmeyer filter flask has the added benefit of preventing overturning. In contrast to measuring cylinders and even breakers, its wide base prevents spillage. In contrast to its wide base, the flask’s tiny mouth reduces its centre of gravity. 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 variety of laboratory flasks includes boiling flasks, cell culture flasks, distilling flasks, Erlenmeyer flasks, filtering flasks, freeze drying flasks, Kjeldahl flasks, recovery flasks, and volumetric flasks. Manufactured from a variety of materials, flasks are typically made of glass or plastic resins such as polystyrene, polypropylene, polycarbonate, polymethylpentene, or PTFE. Depending on their application, flasks can be sealed with various closures, including air-tight screw caps, vent caps, and stoppers made of ground glass, glass, plastic, or rubber.

These characteristics also make the flask suitable for boiling processes. The flask’s conical shape permits the solvent to condense on its body. This prevents loss of solvent. These reactions must be managed, though. They cannot exceed a particular temperature because thermal stress could cause the flask to shatter.

Like beakers, Erlenmeyer flasks are not normally suitable for accurate volumetric measurements. Their stamped volumes are approximate within about 5% accuracy.

Conical flask has a wide range of applications in the chemistry, biology, and microbiology fields for heating, mixing, and transferring chemicals or reagents; Erlenmeyer Flasks and Beakers". www.dartmouth.edu. Archived from the original on 2016-06-16 . Retrieved 2016-06-17. 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.The conical flask may be used to measure the volume of liquids, however its measurements are not exact.
