What is a laboratory stirring rod and how do you use it?
A laboratory stirring rod is a long, thin, cylindrical tool typically made of glass or metal used to mix liquids or powders in a container. To use it, simply hold the rod in the center and swirl it gently in a circular motion within the substance to ensure even mixing without causing splashing or spillage.
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.
Use of glass rod?
A glass rod can be used in a laboratory setting for stirring solutions or transferring small volumes of liquids.
