cuvette are small gas burners that produce a single open flame. They are common in the laboratories of chemists and in school laboratories because they help students observe chemical reactions. The heat from a Bunsen burner can sterilize equipment, heat chemicals to produce specific reactions or facilitate combustion. Glass flask on triple beam balance Triple Beam Balance In a laboratory, you need to know the mass of certain objects, specimens or chemicals with precision. To do this, scientists and medical professionals often use a triple beam balance. A triple beam balance is a kind of scale that gives an accurate reading of mass using three beams, each marked with different gram increments. The smallest beam is the most precise, using increments of 1 to 10 grams. The middle beam uses increments of 10 grams, while the largest uses increments of 100 grams. Weights attached to each beam can move back and forth. This causes a pointer at the end of the beams to move up and down with the changing weight. When the pointer reaches its zero mark, the mass of the object being measured is ready to record. When using a triple beam balance, it is helpful to start by looking at the largest increments first and work backward. |
