often when performing experiments in chemistry you are using dangerous chemicals. the purpose of the glass stirring rod is to a) slowly pour in the liquids so that it will not splash on you or your lab partners and b) to ensure that your pour the right amount of liquid into the solution. i.e. titration. However the main reason for the stirring rod is just to ensure safety.

What are beaker used for?
They are glass vessels used to hold liquids.
What is a glass stir and what is it used for?
It's a short piece of cylindrical glass, usually about 12 cm long. It's used for stirring chemicals together. It's useful because glass is inert to most chemicals and won't contaminate anything.
Why should you never pour hot liquids into a drinking glass?
Rapid temperature changes can cause glass to crack. For the same reason you should never wash a hot glass with cold water.
What is a used stirring rod?

What are the functions of beaker?
To hold liquids and solids. Similar to a glass in a kitchen but used in a laboratory and has a spout for ease in pouring liquids.
What is glass stirring rod used for?
The function is in the name: a glass stirring rod is used to stir solutions or mixtures. Mixing will speed up any reaction that takes place in the test tube or flask. A glass stirring rod can also be used for decanting (pouring off) a liquid from a precipitate or sediment.
What is a laboratory stirring rod and how do you use it?
The Stirring rod is a long rod made of glass, but sometimes plastic, used to stir liquids. The rod is typically as thick as a pencil and between 6 and 12 inches long.

What is stirring rod?
a stewing rod is a piece of rod that is used to season meat for stewing.
Use of glass rod?
Glass rods can be used to stir and displace liquids. Glass is often used because it does not react with many chemicals, especially acids.
What is a glass stirring rod and a rubber policeman and how are they used?
A stirring rod is a glass rod, typically about 6 inches to 1 foot long and 1/8 to 1/4 inch in diameter that can be used to stir liquids in flasks or beakers.You can also use a stirring rod to help pour liquids without spilling. Because of surface tension, liquids tend to run down an object. So if you hold a glass rod vertically, with one end in the opening of the beaker or flask you are pouring into, and then hold the top end of the glass rod against the rim beaker you are pouring out of, the liquid will run down the rod and not spill. Be careful... it might take a little practice to get the proper technique!Sometimes, an attachment called a rubber policeman added to the end of the stirring rod. It is used to transfer residues of precipitates or solids from the inside or beakers, flasks or other glass surfaces. They are often made from rubber, but plastic ones can also be found.See the Web Links and Related Questions for more information and pictures.
