The primary function of a stirring rod is to stir solutions by hand. Stirring rods have other uses in the laboratory, however, including helping to decant liquid from containers, breaking up emulsions and inducing crystallization.Know More
Stirring rods are used to decant or pour liquids slowly. Slow pouring is essential when working with potentially hazardous chemicals that can react too quickly. Using the stir rod to decant liquid makes it easier to keep a precipitate in the bottom of the beaker, because the liquid pours more slowly, reducing the chances of it agitating the solid.
To induce crystallization in a recrystallization experiment, the glass stirring rod is scraped against the inside of the flask containing the solution.Learn more about Chemistry
A glass stirring rod is a common piece of lab equipment used to mix or stir liquids and chemicals. These rods are thicker than a typical drinking straw, have rounded ends and are made from a special type of laboratory glassware called borosilicate. This glass is less affected by thermal stress and has a very low thermal expansion point, so it is less affected by heat than metals are.Full Answer >
A lightning rod conducts a positive charge up to meet the negative charge of a lightning strike, allowing the strike to hit the rod and travel through attached wires to an underground connection. This diverts the strike away from a building, preventing or lessening potential damage, according to About.com.Full Answer >
Monosaccharides are simple sugars that are used primarily as a form of energy for the organisms that consume them. Glucose, which is present in many different types of foods around the world, is the most common type of monosaccharide and is used as an energy source for many animals, including humans. They can be obtained naturally or through a biological process known as hydrolysis performed on either glycosides or polysaccharides.Full Answer >
Enzymes are naturally occurring proteins that are found in the bodies of certain living things, including humans and other animals, and that cause chemical changes such as breaking down food in the stomach. Within the human body, enzymes can be found in bodily fluids, such as blood, saliva, the gastric juices or the stomach and fluids in the intestines. In general, enzymes serve as catalysts for biological functions, including natural, involuntary bodily functions, such as blood clotting.Full Answer >
