A cell spreader is a lab tool used to distribute cells or a liquid over a plate of agar. This little device can be made of glass or plastic, and comes in a variety of sizes and shapes. They can also be sterile or non-sterile.

There are three main types of cell spreaders. These are the T-shaped, the L-shaped, and the plastic model. Each has its own unique features. The T-shaped type is durable and has a smooth head to promote even distribution of cells over the growth media. In the L-shaped type, the upward pointing end prevents agar from tearing.

Plastic cell spreaders are a boon in that they are disposable and don't require sterilization. Another plus is the fact that they are lightweight. However, they do litter the landfills at alarming rates.

In a nutshell, a cell spreader is a small rod or bar with a bent end that spreads cells or a liquid over a plate. While this may sound like a chore, it can be done with little effort. Usually, they are made of polymers and come in sterile or non-sterile versions. Some researchers have favorite designs.

The L-shaped model is a bit trickier to use, but it offers the best of both worlds. Unlike the T-shaped model, it can be applied to the entire surface of a petri dish without tearing the agar. Its other benefits are its ease of handling and its high degree of smoothness.
