A cell spreader is a type of manual device used for spreading cells on culture plates. These devices come in a variety of shapes, sizes, and materials. Some types of cell spreaders are made from glass and metal, while others are made of plastic. They are also available in sterile and non-sterile versions. The most popular spreaders are L-shaped, which are designed to evenly distribute bacterial cultures on the surface of a petri dish or plate.

Another type of cell spreader is the T-shaped cell spreader, which is constructed of durable polystyrene and provides fast and uniform distribution of cells across the surface of a growth medium. It is an ideal choice for transferring bacteria and other cells from a plate or petri dish to a culture flask. Most L-shaped cell spreaders feature an upward end tip, which helps prevent the spreader from tearing the surface of the agar.

Cell spreaders come in a variety of materials, including stainless steel, glass, and plastic. Some of them are made with a smooth head, while others feature a flat or triangular shape. Each type of cell spreader is designed to be reusable and durable, and they can be sterilized.

Bacterial transformation is a key step in molecular cloning. During this process, transformation occurs, which can lead to mutations and transformants with different genetic characteristics. This transformation is performed to maintain the DNA sequences of bacteria. In some cases, a few transformants are produced, but in many instances, the number of transformants is very low.
