What is the difference between Florence flask and volumetric flask?
Florence flask — a flask with a round body and one longer neck without a ground glass joint. Volumetric flask — a flask used for preparing liquids in very precise volumes. It is a flask with a pear-shaped body and a long neck with a line on it which marks the standard volume it can contain.
What is the difference between Erlenmeyer and Florence flask?
Of all the flasks used in chemistry, the most iconic is the conical (Erlenmeyer) flask. Whereas round-bottomed flasks will usually have a ground glass joint on their neck, to allow connection to other apparatus, Florence flasks, supposedly named after Florence in Italy, tend to merely have a lip.
What is a flask used for?
Flasks can be used for making solutions or for holding, containing, collecting, or sometimes volumetrically measuring chemicals, samples, solutions, etc. for chemical reactions or other processes such as mixing, heating, cooling, dissolving, precipitation, boiling (as in distillation), or analysis.
What is the use of boiling flask?
Heating or boiling of liquid, Distillation
Round-bottom flask/Uses
Why is it called Florence flask?
A Florence Flask/Boiling Flask is a type of flask used as an item of laboratory glassware and is named after the city Florence, Italy. It is used as a container to hold liquids. A Florence flask has a round body, a long neck, and often a flat bottom.
What is retort flask?
Retort (glass retort flask, Distillation Retort)is a lab glassware used for distillation or dry distillation of substances. It consists of a spherical vessel with a long downward-pointing neck. The liquid to be distilled is placed in the vessel and heated.
What is Florence flask and its uses?
Boiling, Distillation
Florence flask/Uses
Is it illegal to have a flask?
There is no federal law about this, so it is up to the states to decide whether it’s cool or not, and most states agree: It is not really cool. But flasks exist, legally, because people like sneaking booze, just as head shops and Phish concerts exist because people like pot.
How does a flask work?
A vacuum flask, or thermos, does not allow heat transfer by any of the three ways that heat can travel. The silver coating on the inner bottle prevents heat transfer by radiation, and the vacuum between its double wall prevents heat moving by convection.
What is Florence flask in laboratory?
A Florence Flask/Boiling Flask is a type of flask used as an item of laboratory glassware. It is used as a container to hold liquids. A Florence flask has a round body, a long neck, and often a flat bottom.
What is the purpose of the glass vial that is placed inside the Florence flask?
It is designed for uniform heating and ease of swirling; it is produced in a number of different glass thicknesses to stand different types of use. They are often made of borosilicate glass coated with alkali [citation needed] to prevent cracks or defacing of the glass. The flask is named after Florence, Italy.
Who invented the Florence flask?
German scientists Otto Schott (1851–1935) and Ernst Abbe (1840–1905) first developed borosilicate glass in the late 19th century.
What kind of flask is a Florence flask?
A Florence Flask / Boiling Flask is a type of flask used as an item of laboratory glassware. It is used as a container to hold liquids. A Florence flask has a round body, a long neck, and often a flat bottom.
What kind of Flask has a flat bottom?
A Florence flask has a round body with a single long neck and with either a round or a flat bottom. A Florence flask with a flat bottom may stand upright alone on a flat surface; flasks with round bottoms need support to stand upright.
What kind of glass is an Erlenmeyer flask?
An Erlenmeyer flask (also known as a conical flask) is a type of laboratory glassware which consists of an inverted conical base with a cylindrical neck. What are Erlenmeyer flasks used for?
Can a hot flask be placed on a cold surface?
A hot flask should never be placed on a cold surface as this may cause it to crack. They should be carefully inspected before use in case a crack is present. Needless to say, putting a cracked vessel over a heat source is not to be recommended. Certain chemicals may also damage the glass of the vessel.
