Huixi Brush is a professional test tube brush manufacturer based in Shanghai, China. Our test tube brushes are constructed with a twisted stainless steel wire core that holds the bristles firmly in place throughout the length of the brush, providing durable, resilient cleaning action inside glass and plastic test tubes, laboratory glassware, drinking straws, spray nozzles, and other small-diameter cylindrical vessels. A wide range of filament materials is available to suit different cleaning requirements and applications.

Available Filament Materials

• PA66 nylon — The most common choice for general laboratory and industrial tube cleaning. Durable, moisture-resistant, and available in a range of stiffness grades and colors.
• Polypropylene — Chemical-resistant bristles suitable for cleaning tubes exposed to acids, alkalis, or solvents.
• Cotton fiber — Soft, absorbent bristles ideal for oiling, dusting, applying coatings, and gentle cleaning of delicate glass surfaces.
• Tampico (Mexico fiber) — A natural plant fiber with good moisture absorption and moderate stiffness. Suitable for wet cleaning applications and food-contact surfaces.
• Sisal fiber — A firmer natural fiber providing more aggressive scrubbing action for removing residue from tube walls.
• Coconut fiber — Coarse natural fiber for heavy-duty scrubbing of stubborn deposits in tubes and pipes.

Common Applications

• Laboratory test tube and glassware cleaning
• Flask, beaker, and graduated cylinder washing
• Drinking straw and reusable straw cleaning
• Spray nozzle and nipple brush cleaning
• Small-diameter pipe and tube cleaning in food processing
• Oiling and lubricating small bores and channels
• Dust removal in precision instruments and electronics

Construction

All test tube brushes use a twisted stainless steel wire core for corrosion resistance and long service life. The twisted construction locks bristles securely at consistent intervals along the full brush length. Custom outer diameter, overall length, bristle length, core wire gauge, and handle style are available on request.
