Also known as an Erlenmeyer flask, a conical flask is a glass vessel used in chemistry laboratories, and it has a wide flat bottom that tapers up into a narrow cylindrical neck. They're usually used for mixing liquids.Know More
Invented by the German chemist Emil Erlenmeyer, conical flasks are generally found in laboratories. The wide base and narrow neck of the glass flask makes them perfect for swirling liquids or other compounds together. The contents of the flask stay inside and don't spill. Some Erlenmeyer flasks have measuring marks up the side and sometimes have a spot for a penciled-in label. Stoppers of cotton, rubber, or glass may be used. The contents can also be heated on a burner, although a round-bottomed flask is preferable.
Plastic Erlenmeyer flasks can be used to grow microbial cultures in laboratories for microbiologists. Its unique shape promotes and enhances growth with the correct ventilation.Learn more about Chem Lab
The vacuum effect of a filter flask is used to filter laboratory samples. A filter flask is an Erlenmeyer flask with a specialized arm on the side. This arm connects to a vacuum pump or aspirator, creating a vacuum and lowering the pressure inside the flask.Full Answer >
A volumetric flask is glassware used in laboratories for measuring volume in the preparation of solutions and holds a precise amount of liquid material when at room temperature. These flasks are calibrated using global standards and come in sizes up to 10,000 milliliters.Full Answer >
A flat-bottomed flask is used in a chemistry laboratory for experiments that involve collecting and measuring liquids, mixing solutions and cultivating media. The design and construction of the flat-bottomed flask allows it to stand alone on the lab bench.Full Answer >
A conical pendulum is a weight fixed on the end of a string or rod suspended from a pivot so that it can swing freely. A conical pendulum construction is similar to an ordinary pendulum; instead of swinging backward and forward, the weight moves at a constant speed in a circular motion with the string or rod tracing out a cone.Full Answer >
