What is the name for a conical glass flask with a narrow neck and broad base?
Volumetric flask - used to prepare a standard solution in laboratory
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
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.
Which vessel is more appropriate for mixing by swirling a beaker or an erlenmeyer flask?
The Erlenmeyer flask's narrow neck allows more vigorous swirling without as much chance of spilling as with a beaker or other wide mouth vessel.
What is the standard specification for rain gauge?
believe a std gauge has s catchment neck of 112,82 mm diameter, thus every 1,,mm that falls on that spot, will measure 1cc (or 1ml) in a seperate measuring flask. no maths needed! Some manufactures adapt the graduations on an integral flask to allow for a different neck size
What is a florence and how is it used?
A florence flask (also known as a boiling flask) is a type of flask. It is a piece of laboratory glassware. It can hold chemical solutions. The flask has a round body with a long neck. The flask usually come in volumes of 1 liter. It is similar in shape and function to a round bottom flask. See the Web Links and Related Questions to the left for more information.
What is a distillation flask?
A distilling flask is a round bottom flask that often has two openings, and some of them have a long neck.it is used for distillation processes. See the Web Links to the left for pictures and more information about how to use a distilling flask.
What is distillation flask?
distillation flask is often round bottomed flask with with few cylindrical openings such as cylindrical neck and side ones, the neck host a thermometre and the sideo one connected to a condenser to cool the vapors back to liquid state,
What is a florence flask and how it is used?

What is the round bottom flask use for in chemistry?
The round bottom flask is used frequently for distillation.
What is a florence flask is used for?
A florence flask is a round bottomed flask used for boiling.
How do you hold and move a flask if you are mixing chemicals?
you hold the flask by its norrow neck to move it
What is a comical flask?
The correct spelling is conical flask. A conical flask is a type of flask that is used in laboratories. They have a conical body, flat bottom, and cylindrical neck.
What is the function of round bottom flask?
A round bottom flask is called a boiling flask. I tolerates the stresses of heating better than flat bottom or Erlenmeyer flasks.
How did pasteur settle the spontaneous generation argument?
Quite. By sealing meat away from atmosphere he showed that maggots do not spontaneously generate out of meat not landed on by egg laying flies.PS: Abiogenesis is not spontaneous generation!
What science tool is Glassware with a narrow opening on top?

Why pear shaped flask is used instead of round bottom flask?
even distribution of heat
