The Laboratory Brush is a brush used for cleaning test tubes and glass utensils such as beakers and flasks. It is comprised of nylon, animal, or synthetic leather bristles of various diameters lined up against a sturdy wire handle with a looped end for hanging. The wire is metallic, it can be made of aluminum , bronze , beryllium , copper or brass . They are designed to be resistant to acids and other corrosive chemicals.

Technical details
The brush bristles can be made of:
- Nylon.
- Goathair .
- White or black wool bristles.
- Polyester.
- Polypropylene.
The sizes of the brushes are determined by their diameter . This is according to the laboratory instrument to be cleaned. The manufacture of the brushes consists of a galvanized wire (handle) that when twisted holds the filaments (bristles) in a cylindrical shape
Features and shapes
- It has nylon, animal fur or synthetic bristles.
- The hairs of the laboratory brush have different lengths and are attached to a sturdy wire.
- The central wire has a loop at its end to hang the brush.
- The wire is made of metal that can be aluminum, copper, bronze , brass, or beryllium .
- The lab brush is made to be resistant to acids and corrosive chemicals.
- Test tube brushes can range in size from 10mm to 2m in length and 3mm to 20cm in diameter.
Uses and applications
The brush is designed for cleaning surfaces found inside parts that are small or difficult to access. With the brush we can get to touch the interior walls, as well as the most inaccessible funds. They are designed to be able to reach narrow openings that would be inaccessible areas without a laboratory brush.
The laboratory instruments that we can clean with the brushes are: • Glass or plastic specimens
- Tubes
- Centrifuge tubes
- Beakers
- Burette
- Pipette
- Jars
- Bottles, etc.
Test tube brushes come in sizes ranging from 10mm to 2,000mm in length and 3mm to 200mm in [[diameter. The brushes are designed for the purpose of cleaning test tubes, therefore different types are developed to be able to reach all corners of the glassware.
| Tip type | Description |
| Radial tip | Rounded tufo tip allows for a curved brush edge, protecting glass from contact with twisted metal wire handle |
| Radial Tip of Steel Wire Stem | Like radial tip brushes, but more durable and efficient in cleaning glassware. |
| Linked tip | The bristles are tied together at the tip to facilitate cleaning tubes and bottles with narrow openings, capable of expanding at the bottom of the tube without scratching the surface. |
| Sponge tip | The soft tip allows for liquid expansion and absorption, resulting in more thorough tube cleaning and scratch protection. |
