Science Lab Supplies offers the brush from Ambala, India to schools, colleges, laboratories, tender contractors and distributors.

Specifications

The brush has a round head of soft nylon bristles, 12 mm in diameter, which fits inside standard test tubes and reaches the rounded bottom. The bristles are white and soft, so they clean without scratching glass, and the brush is also used for cleaning bottles.

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 used 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 that wash large numbers of tubes 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.

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.

Standard Scope of Supply

The Brush for Washing Test Tubes is supplied as a single round nylon brush with the specification above; quantities for a whole laboratory are shown on the quotation, with any drying racks or wash bottles listed as separate lines.
