Applications and Experiments for the Test Tube Brush
The brush reaches into narrow glassware that a sponge cannot, clearing precipitates, films and culture residues from test tubes, culture tubes, small cylinders and vials. Clean glassware is the first step of a reliable practical, so a pack of these is useful school chemistry lab equipment in India.
- School chemistry labs: cleaning rimless 12 x 100 mm glass tubes such as the Test Piece after precipitation and salt analysis practicals.
- Microbiology and biology labs: scrubbing culture tubes before disinfection.
- College and research labs: clearing small graduated cylinders and sample vials.
- Lab assistant training: glassware washing procedure, worn with a waterproof Apron for Chem lab.
Wet the brush in warm detergent solution, twist it in both directions while working along the tube walls, then rinse with distilled water. Never force an oversized brush into a narrow tube: the glass can break and cause injury.

Frequently Asked Questions
How long is each brush?
Each brush is 8 inches (200 mm) long overall, with a 3-inch (75 mm) bristle section 0.75 inch (19 mm) across, sized for standard-depth test tubes and small containers.
Will the bristles scratch glassware?
The nylon bristles scrub without scratching inner glass or plastic surfaces, and the radial fan tip covers the wire end, which helps protect the curved bottom of the tube while you scrub.
Who supplies these brushes?
Packs of 12 are sourced and dispatched by Science Lab Supplies in Ambala, India, and can be quoted alone or with wash bottles, racks and other glassware cleaning items for a laboratory.
Which cleaning agents can the brushes be used with?
They resist common lab detergents, mild acids, alkaline disinfectants and sanitising solvents. After washing, hang the brushes by the wire loop so they can air-dry before the next session.
