Laboratory Brush for Pipettes and Narrow Tubes

Cylindrical laboratory brush with an elongated geometry and slightly tapered profile, specifically designed for cleaning the internal surfaces of pipettes and small-diameter tubes. Its effectiveness is determined by the brush diameter and bristle configuration, ensuring uniform contact with internal walls and efficient cleaning without damaging the material.

General Features

• Cylindrical brush with progressive profile, designed for insertion into pipettes, tubes and cannulae.
• Natural goat hair bristles, soft and flexible, suitable for delicate surfaces.
• Handle made from galvanised steel wire, providing corrosion resistance.
• Long, flexible structure for easy access to deep and narrow areas.
• Looped end for convenient hanging and storage.
• Tufted tip for effective cleaning at the bottom of vessels.
• CE origin.

Applications

• Cleaning of volumetric and graduated pipettes.
• Cleaning of cannula and small-diameter tubes.
• Narrow-neck vessels where correct diameter matching ensures optimal performance.

Technical Specifications

The brush features a 22 mm diameter and a 70 mm bristle length, providing an effective cleaning surface for narrow internal passages. The cylindrical shape with a slight taper allows smooth insertion and improved contact with internal walls.

The total length of 480 mm enables comfortable use in long and deep items such as pipettes. The galvanised wire handle offers controlled flexibility, adapting to the internal geometry without permanent deformation.

Functional Design

The performance of the brush depends directly on the relationship between its diameter and the internal diameter of the vessel. Proper matching ensures uniform cleaning, while the softness of natural bristles prevents scratching of glass or plastic. The elongated geometry and tufted tip allow precise access to the bottom and hard-to-reach areas.
