Product Code : SCL-CL-12009
Test Tube Brush lab (SKU SCL-CL-12009) is an 8-inch cleaning brush with radial nylon bristles on a twisted wire stem, used to scrub residues from the narrow inside surfaces of test tubes and small laboratory containers. Regular brushing prevents one experiment contaminating the next. Lab technicians, teachers and chemistry students use it daily in school, college and research labs. The brushes come in packs of 12, and Science Lab Supplies dispatches them from Ambala, India to schools, colleges, institutes, tender contractors and distributors.
Specifications
Each brush has high-density nylon bristles wound into a twisted galvanized steel wire stem, 200 mm long overall with a 75 mm brush section 19 mm across. A radial fan tip protects the tube bottom, and a wire loop at the base serves as a grip and for hanging.

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 every reliable practical, so a pack of these is standard school chemistry lab equipment in India.
- School chemistry labs: cleaning test tubes 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: routine glassware washing procedure.
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.
Standard Scope of Supply
One pack contains 12 Test Tube Brushes, 8 inch, with nylon bristles, plus a glassware maintenance and cleaning guide. Detergents and disinfectants are not included; wash bottles and test tube racks are listed separately.

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 are gentle on glass and plastic, and the radial fan tip covers the wire end, which helps protect the curved bottom of the tube while you scrub.
Who ships these brushes?
Science Lab Supplies ships them from Ambala, India, in packs of 12, as part of its supply of laboratory cleaning items and glassware.
Can the brushes be autoclaved?
The wire tolerates heat, but repeated autoclaving can soften the nylon bristles over time. Disinfect with a liquid sanitising solution instead, then hang the brushes to air-dry.
