Every week, we bring you the latest in lab technology. Today, Shanghai Hengyuan shares some essential lab tips, including a detailed guide on how to properly clean laboratory instruments.
1. For glassware that has residues of alkali, alkaline oxides, or carbonates—substances that are not easily dissolved in water—first treat them with dilute hydrochloric acid before rinsing thoroughly with water.
2. When dealing with waste, make sure to pour solid waste into the designated waste container and liquid waste into the appropriate waste tank. If there are any useful substances left, transfer them to the correct storage area.
3. For greasy glassware, start by washing with a hot solution of sodium carbonate (Na₂CO₃) or commercial washing powder, then rinse with clean water until it's completely clean.
4. After cleaning, never leave the equipment scattered around. For example, once a test tube is cleaned, place it upright in the test tube rack to air dry.
5. The standard for clean glassware: when water runs off the surface, it should not form droplets or run in streams. Instead, it should evenly coat the surface and drain smoothly.
