Applications and Experiments for the Brush for Washing Test Tubes
Clean glassware is the first condition for reliable results, so a test tube brush is needed after almost every practical. It serves school science labs from Class 6 upward, Class 11–12 chemistry and biology practicals, and college and diploma laboratories where many tubes must be washed each day.
- School science practicals: cleaning Test Tubes after reaction and indicator activities.
- Class 11–12 salt analysis: removing precipitates and residues between tests.
- Biology practicals: cleaning tubes used for food tests.
- Laboratory preparation rooms: washing narrow bottles and sample tubes with detergent while wearing disposable Gloves Protective.
Wet the tube with water and detergent, turn the brush gently rather than pushing hard against the bottom, then rinse with clean water and let the tube drain upside down.
