What is a graduated cylinder and how is it used?
A graduated cylinder is a piece of laboratory glassware, cylindrical in shape and graduated, used to accurately measure out volumes of liquid reagents for use in reactions.Related Information:They are generally more accurate and precise for this purpose than beakers or Erlenmeyer flasks, although not as precise as a volumetric flask or volumetric pipette. They come in a variety of sizes for different volumes, typically 10 ml, 25 ml, 50 ml, or 100 ml, 500ml, and up to 2 liters. Measuring cylinders are sometimes used, if they can measure the quantity desired.Determine the volume contained in a graduated cylinder by comparing the bottom of the meniscus (the curved surface of the liquid) to the nearest graduation, at eye level.
Is a graduated cylinder more accurate than a beaker?
As a chemist I can tell you that there are a significant purpose differences between the two, though sometime masked in high school chemistry. In college you learn that the graduated cylinder are more specifically designed to measure volume of a liquid. The test tube is glass which is safer to do most chemical reactions in - meaning the test tube is not generally used for measurement but rather a container for liquids.
What piece of eqipment might be used for dispensing liquids?
either an Beaker,and graduated Cylinder
If you have been asked to accurately measure out 50 cubic centimetre of a liquid experimentwhich piece of glassware wouls you use explain and justify your answer?
A 50ml fixed volume pipette. Graduated pipettes are less accurate, multiple pipettes are bad for accuracy, and most other glassware is bad for accuracy. Also look for the highest class pipette available
Use of erlenmeyer flask?
Physical DescriptionAn Erlenmyer Flask (named after Emil Erlennmeyer) is a common piece of laboratory glassware since 1861. It is also known as as a conical flask or E-flask. It has a conical body, flat base and a narrow cylindrical neck. The flask is usually marked to indicate the approximate volume of their contents.The flask is chosen to replace a beaker if there is a need to stopper the contents. The narrow neck is sized to accept standard rubber stoppers or corks.The conical shape and narrow neck facilitates stirring by swirling.The small neck reduces evaporates losses. The neck may be fitted with side tubes to allow the extraction of produced gasesThe flat bottom improves stability on lab benches. A Florence flask has a similar overall use but is more unstable because the body is round and the base is smaller.UsesErlenmeyer flasks are used for:pH tit rationsthe preparation of mixtures which must be mixed without Starr
What piece of glassware is used to prepare very accurate concentrations of chemical solutions?
a volumetric flask
What is a florence flask and how it is 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.

Give the glassware used for direct heating 5.0ml of a liquid?
The preferred piece of laboratory glassware to heat 5ml of a liquid is a small round bottom flask. These are also known as boiling flasks.
What are graduated cylinder and how are they used?
a graduated cylinder is a piece of lab glassware used to hold liquids. 'graduated' means it has a scale of measurement (usually in mLs) to measure liquids. make sure to always measure at the bottom of the miniscus for accurate data.
Why shouldn't you use a chipped piece of glassware?
Chipped glassware is much more likely to shatter fully than unchipped glassware under thermal or mechanical stress.
If you were asked to add 50 mL of a stock solution to a reaction vessel which piece of glassware would you use to obtain this volume of solution?
You can use a graduated cylinder or a pipette of 50 mL.
What is used for graduated cylinder?
A graduated cylinder is a piece of laboratory glassware used to accurately measure out volumes of chemicals for use in reactions. They are generally more accurate and precise for this purpose than beakers or erlenmeyer flasks, although not as precise as a volumetric flask or volumetric pipet. They come in a variety of sizes for different volumes, typically 10 ml, 25 ml, 50 ml, or 100 ml and up to as large as 1 or 2 liters. Determine the volume contained in a graduated cylinder by reading the bottom of the meniscus at eye level.

What do you do if you get a small cut from a piece of glassware?
first you wash your cut of then you put neosporian on it
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 do you call a piece of metal used to hold and support glassware?
for test tube you will need a test tube holder , and for hot glassware you will need a crucible tongs. Enjoy
