What are the precautions for conical flask?
Usually they are handled by gripping the neck of the flask from the side. Get in the habit of never allowing you hand to be over the opening in the neck. Sometimes the fumes coming out through the throat of the flask can be hot or corrosive and burn you.
What is a narrow-necked glass container with a flat bottom but a round lower part used to holdmixheat materials in science?
A flask. See http://www.indigo.com/glass/gphglass/volumetric-flask.html
Water will move higher in a narrow glass tube than in a wide glass tube because of?
It is because of Capillary action, the adhesive forces for water are effective in narrow tube, in a wide tube the weight of water resists the upwards movement of water.
What does a cordial glass look like?
A cordial glass is a tall, narrow, and cylindrical glass that usually flares out at the top. Some styles of cordial glasses have a stem while several other types do not.
What are the two most commonly used flasks?
Laboratory Glassware: Types of Laboratory FlasksFlasks are useful tools for containing liquid and performing mixing, heating, cooling, precipitation, condensation and other processes. They come in a range of sizes, materials and uses. Commonly used laboratory flasks include:An Erlenmeyer flask, conical, or E-flask is one of the most commonly used flasks in scientific laboratories. The flask has a conical base that almost extends into a small, cylindrical neck. This shape allows the flask to be sealed with a bung for heating purposes, while also allowing a researcher the freedom to shake or stir the flask without spilling liquid. The Erlenmeyer flask has diverse uses such as holding and measuring chemical liquid samples, but can also be used to mix, heat and boil chemicals.A Büchner, or sidearm flask is essentially an Erlenmeyer flask (see above) with an additional small tube extending from the side of the neck. The bottom is conical in shape, with a short neck from which the small tube extrudes. The entire flask is made of thick glass. The small side-arm tube is composed of a hose barb, which is a serrated section that catches a thick-walled flexible hose. Because of this design, a Büchner flask is well-equipped for creating vacuums with the help of a Büchner funnel. 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.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. Because they are so often used for boiling, Florence flasks are produced with borosilicate glass to prevent cracking.A retort is a type of flask used primarily for distillation and its design is exclusive to this purpose. The retort resembles an exaggerated teardrop with the middle bent at almost a 90 degree angle. The bulb portion contains a liquid or chemical solution, which is heated to the point of condensation. The condensation then attaches to the roof of the retort, and as it begins precipitating, it runs down the angle of the long, thin point of the tear where there is another opening. The liquid collects in a separate container.A Schlenk flask can be a round, pear-shaped or tubular bulb that stretches vertically into a long, thin neck with a side-arm. The side arm features a valve so that pressure or gas can be released from the flask.Volumetric flasks are flasks used to measure specific volumes of material. They are generally gradated with metric markings to measure the volume of material in the container. They are typically composed of a round or pear-shaped bulb and a long thin neck topped by a stopper or rubber bung. Because they are generally used for measurement or reactions and not heating or boiling, they can be made of plastic or glass.-http://www.thomasnet.com/articles/instruments-controls/types-of-lab-flasks
Why is conical flask called conical flask?
The conical flask is named after its shape, which resembles a cone. It typically has a flat bottom, a conical shape, and a narrow neck. This design allows for easy swirling of liquids and helps in preventing splashing while mixing or reacting substances.
What is Erlenmeyer flask and its uses?
Erlenmeyer flask is a conical flask made from glass or plastic, sometimes graduated or with a stopcock; uses: - to contain liquids or powders - to realize chemical reactions - it is the preferred flask for titration - heating of liquids (only in Pyrex glass) See also the link below.
Are conical flasks used for?
its used to put chemicals in or you can make the chemicals yourself!!!A glass laboratory flask of a conical profile with a narrow tubular neck and a flat bottom, used to manipulate solutions or to carry out titration.
The definition of conical flask?
A conical flask is a glass container with a wide, flat bottom and a narrow neck. It is mainly used in chemistry laboratories for mixing, heating, and storing liquids. The conical shape helps in swirling or mixing liquids without spilling.
What is a conical flask used for?
An Erlenmeyer flask, commonly known as a conical flask or E-flask, is a widely used type oflaboratory flask which features a conical base and a cylindrical neck. They are usually marked on the side (graduated) to indicate the approximate volume of their contents. It is named after the German chemist Emil Erlenmeyer, who created it in 1861.
What is the titration flask?
A titration flask is a glass vessel with a narrow neck and a flat bottom used in titration experiments. It typically has volume markings for precise measurement of liquids added or titrated during the experiment.
What glass container has a narrow neck and is useful when heating liquids?
Flask

What is a Erlenmeyer cylinder?
This is a conical flask from glass or plastic, frequently used in all chemical laboratories; the Erlenmeyer flask may contain reagents, collect filtrates, labware for a chemical reaction, it is used for titration, etc. It is not a cylinder.
What is a flask used for?
AnswerA flask is a container for storing or carrying liquid.It also keeps the liquid at the same temparature over a number of hours. A flask is nominally used for carrying liquids in it and usually of the alcoholic nature, and is usually referred to as a hip flask as it is carried in a pocket either the front or back.
What is the definition of flask?
noun. any of various small containers made of glass, metal, etc., with a narrow neck.
