Use of glass rod?
A glass rod can be used in a laboratory setting for stirring solutions or transferring small volumes of liquids. It is also commonly used in physics experiments to demonstrate the principles of refraction and total internal reflection. Glass rods are non-reactive and have a smooth surface, making them suitable for a variety of applications.
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.
Uses of stirring rod?
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.
Are ethanol resistant markers suitable for use in laboratory settings where exposure to ethanol-based solutions is common?

What is stirring rod?
A stirring rod is a tool used in the laboratory to mix or stir substances in a beaker or test tube. It is typically made of glass or metal and is long and slender, allowing for easy manipulation and thorough mixing of liquids or solutions.
Should you use a laboratory thermometer for stirring and why?
It's best not to, as thermometers can be quite fragile. A glass rod is preferable. (That said, you can get so-called stirring rod thermometers, made to be more robust, but they tend not to be very accurate and are really only meant for lower grade chemistry.)
Precautions with using a stirring rod?
When using a stirring rod, the main precautions to take are to handle it carefully to avoid breakage or splintering, use appropriate PPE like gloves and safety glasses to protect yourself, and never put the rod in your mouth to avoid potential contamination. Lastly, always clean and store the stirring rod properly after use to prevent any cross-contamination.
What is a used stirring rod?
