The small side-arm tube is composed of a hose barb, which is a serrated section that catches a thick-walled flexible hose. With the funnel on top of the glass neck and a tube sucking the pressure out of the side, vacuums for sluicing liquids can be created very easily within the flask.
A fleaker is a portmanteau of the words flask and beaker, and physically resembles a combination of an Erlenmeyer flask and a beaker. The cylindrical body culminates in a neck that curves inward before flaring out in a rounded opening. Fleakers are generally used for similar applications as Erlenmeyer flasks, but most often only for liquids. What is a Florence flask? A Florence, or boiling flask is a large, round sphere with a long, thin neck and a slightly flared rim opening.
The rounded design of the bottom is such that a Bunsen burner can easily heat the solution within. Some Florence flasks are produced with rounded bottoms, and thus need support in order to stand upright; others have flat bottoms and can stand alone.
It consists of a wide base with a flat bottom and an inverted cylindrical neck. They are usually constructed out of glass or plastic, and fitted with ground glass at the neck. Otherwise, there are usually spots of enamel and ground glass where they need to be labeled with a pencil. The use in biology to generate certain bacterial and mammalian cells has proven to be of great importance for research. Erlenmeyer conical flasks come in various sizes including mL, mL, mL, and mL.
These different sizes make it ideal for conducting experiments in various laboratories of different sizes.
Erlenmeyer flasks are great for mixing chemicals since they have a wide base and can be swirled around without spillage. Since the base is wide, there is less danger of the liquid rising to the top and spilling out. The Erlenmeyer filter flask also has the advantage of avoiding tipping over. Unlike measuring cylinders and even breakers, its wide base keeps it from spilling.
The narrow mouth of the flask in contrast to its wide base lowers the center of gravity. This is why samples or mixtures are not generally stored in beakers.
Due to the narrow mouth, the conical flask is also used for filtering different samples with filter paper. They are not very precise in their measurement and are made to contain chemicals or reactions. If a beaker needs to be heated, a hot plate is ideal, but a Bunsen burner and beaker holder will also work.
Although most types of beakers are made of glass, plastic beakers are also available. Erlenmeyer flasks are flat-bottomed flasks that are similar to beakers, except that the sides taper in as they go up and form a narrow vertical neck. They also typically have measurement markings and pour spouts. They are typically used when chemicals need to be heated because their tapered sides help keep some of the heat in that might otherwise be carried away by evaporating materials.
They can be heated over a Bunsen burner or a hot plate. Round bottom or boiling flasks do not stand up on their own and must always be held by a clamp. They typically do not have markings other than a mark approximating maximum volume or pour spouts. They can be heated by Bunsen burner, or by a special type of hot plate that is made to accommodate the round bottom. Volumetric flasks are a very precisely made type of science flask.
They are made to measure out extremely accurate volumes of liquid. They typically have a bulbous bottom that may or may not be flat, and a very long, very narrow neck.
