Why Cell Culture Dish Is Round

Have you ever wondered why a cell culture dish is round? It is a very interesting question and there are several reasons for it. Now you can keep reading below:

Why Cell Culture Dish Is Round:

  • The first reason is to make it more durable. If it is of any other shape, heavy objects are placed upon it, and the corners are liable to be broken by uneven forces.
  • The second reason is to save raw materials. In the case of circles and other shapes of the same diameter, circles consume less material and save the raw material.
  • The third reason is that early experimental equipment mostly used glassy materials, and the circular shape was relatively easy to produce. When demolding or cooling, one should be careful about the concentration of stress in the corners, which can cause the finished tool to break. At the same time, the disinfection of cell culture dishes is usually done using steam or simple lamp-baking methods, and no corners are broken due to thermal expansion and contraction.
  • This is also because circular dishes are convenient for dosing operations, and circular cell culture dishes are easy to wash, cleaning will be more thorough, and there will be no contamination in corners and crevices that cannot be cleaned. Contamination is a big concern for all labs, and a round shape is more likely to prevent contamination. Now with sterile disposable cell culture dishes, these will not have many cleaning problems. And people have been using round cell culture dishes that are comfortable to handle, which has become a habit. The round dish has been used continuously in the experiments.

The above is the reason why cell culture dishes are circular, as the many advantages mentioned above facilitate experiments. Having spoken of its benefits, let us present cell culture dish uses in contributing to the development of mankind.

Round Dish Application:

Cell culture dishes are available in glass and plastic. Glass dishes can be used for plant material, microbial culture, and adherent culture of animal cells. Plastic dishes are suitable for the cultivation of microorganisms, laboratory inoculation, streaking, and bacterial isolation operations, and can also be used for the cultivation of plant materials.

The cell culture dish is mainly used to hold the medium for cell culture. A cell culture dish uses to store sterile cultures of various cells, bacteria, fungi, and other microorganisms. And it can be used for basic analysis in medicine, biology, science, and others. It can also play a role in scientific research fields such as agriculture and aquaculture and can be used for the artificial cultivation and hatching of seeds, plants, insects, and fish.

All three cell culture vessels are mainly used for cell culture in the laboratory. The cell culture flask is a sealed culture, which can reduce pollution; The cell culture plate and the cell culture dish are semi-open cultures, which is convenient for comparison experiments and gradient experiments. It is less pollution-proof, and more demanding on operators. Cell culture plates, dishes, and flasks are suitable for small-scale cell culture in the laboratory. In terms of cell culture status, there is not much difference between cell culture flasks and cell culture dishes. Nevertheless, cell culture flasks can hold more cells than cell culture dishes. But the cost of the cell culture flask is comparatively high. So cell dishes are generally chosen if there are no special requirements. If you have purchasing needs for laboratory consumables, Hawach hopes to be your choice.
