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.

This flask is not used for measurement, as its primary use is to hold and mix liquids. Due to the flask’s irregular shape, it is not appropriate for measuring purposes.There are two types of conical flasks available in a variety of sizes. Mostly made in clear glass, some versions are made in an amber colour to protect light-sensitive chemicals.

After completing the experiment, the flask should be rinsed for 10 to 15 minutes with a warm detergent solution. Then, rinse it with tap water. 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] The conical flasks can be used for various purposes like mixing, heating, and storing chemicals or reagents.

They may be graded, and spots of ground glass or enamel are frequently used for labelling purposes. The inside of the mouth of Erlenmeyer flasks may be frosted to accommodate a ground glass stopper. Alternatively, a cap or rubber stopper may be used to contain the contents. Some Erlenmeyer flasks include a side arm (or one can be attached) to enable filtering. Vessels used for containing liquids and performing mixing, heating, cooling, incubation, filtration, storage, distillation, volume measurement, and other common liquid handling processes. Sentek has been specialising in the field of scientific equipment since 1991. Our range of sensors and temperature probes now represent essential equipment for all types of chemical testing applications involving conical flasks. Though our products are essentially scientific in nature, they are commonly used in a variety of everyday processes, from food to education.

Laboratory flasks are found in most chemical, biological, clinical, and industrial laboratories and in a variety of other workplace settings. They are available in a range of capacities ranging from 10 mL up to 10 L. Depending on the type, they may be supplied with a jointed ground glass top, a glass or plastic stopper, or a screw top. There are a couple of international standards relating to conical flasks, so we've chosen one to break down and explain to keep you informed and up to date with quality requirements for laboratory equipment. The conical flask’s rounded and thin mouth makes pouring easier. However, the beaker’s top spout makes it simple to pour chemicals. 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.
