Square and Round Media Bottles

Square media bottles are frequently used in autoclaving processes. This is because it is often necessary to pack as many bottles as possible into the autoclave for space savings and efficiency. Because many parts of the process are time sensitive, micro labs must process samples quickly. They also have to make large amounts of media and agar on a regular basis, and they've discovered that racks of square bottles are much easier to manage. Square media bottles are also commonly used to store granular solid chemicals.

In analytical laboratories, rounded media bottles are more common. This is because rounded containers are easier to mix and stir than square containers. In these laboratories it is important to ensure solutions are effectively mixed to form homogenous solutions.
