Every week, we bring you the latest in lab technology. Today, Shanghai Hengyuan shares some essential lab tips, focusing on how to properly clean laboratory instruments. Whether you're a student or a professional, understanding the correct cleaning methods is crucial for maintaining accurate and reliable results.
1. For glassware that has residue of alkali, alkaline oxides, or carbonates—substances that are not easily dissolved in water—start by rinsing with dilute hydrochloric acid, followed by thorough washing with tap water.
2. Always dispose of waste residues and liquids properly. Pour them into the designated waste containers. If there are useful substances left, transfer them to the appropriate storage containers for future use.
3. If your glassware is contaminated with grease, first wash it with a hot solution of sodium carbonate (Na₂CO₃) or a commercial washing powder. Afterward, rinse thoroughly with water to remove all traces of the cleaning agent.
4. Once cleaned, never leave instruments scattered around. For example, after cleaning test tubes, place them upright in a test tube rack to air dry. This helps prevent contamination and keeps your workspace organized.
5. The standard for properly washed glassware is when the water runs off evenly without forming droplets or flowing in streams. This indicates that the surface is clean and free from any residual substances.
