An L-shaped glass spreader is a laboratory tool used for spreading liquids and solutions evenly on a surface. The spreader is typically made of glass and has an L-shape design, with one end being rounded and the other end being flat. The rounded end is used to pick up a small amount of liquid, while the flat end is used to spread the liquid evenly across a surface.

The L-shape design allows for a comfortable grip and improved control during the spreading process. Glass spreaders are commonly used in a variety of laboratory and industrial applications, including sample preparation, quality control testing, and surface analysis.

The combination of the L-shape design and the glass material make the spreader a useful tool for precise and efficient spreading of liquids.
