Once you are done using a test tube, properly dispose of its contents according to your laboratory's safety and waste disposal guidelines. If the contents are hazardous, use a designated waste container for hazardous materials. If they are non-hazardous, you may dispose of them down the sink with plenty of water, ensuring compliance with local regulations. Always clean the test tube thoroughly before storing it for future use.
If you are done using a test tube, first ensure that you properly dispose of its contents according to safety guidelines and material type, such as pouring liquids down the sink (if safe) or placing solid materials in designated waste containers. Clean the test tube thoroughly with appropriate cleaning agents and rinsing with water. Finally, if the test tube is reusable, store it in a clean, designated area; if it’s broken or contaminated beyond use, dispose of it in proper hazardous waste containers.
