Laboratory Bioreactors and Cell Culture Bioreactors

A laboratory bioreactor is a device used in a laboratory setting to create a controlled environment for the growth and manipulation of cells or microorganisms. It allows for precise control of parameters such as temperature, pH, dissolved oxygen, and nutrient supply.

A cell culture bioreactor is specifically designed to meet the unique requirements of growing and maintaining cells. It often has features to ensure optimal cell growth, such as gentle agitation to prevent cell damage and specialized surfaces for cell attachment and proliferation.

A wide variety of cells can be grown, including mammalian cells, microbial cells like bacteria and yeast, and plant cells. The choice of bioreactor and its configuration depends on the specific type of cells being cultured.

You need to consider factors such as the volume of culture needed, the type of cells or microorganisms, the control parameters required, and your budget. Also, the ease of operation and maintenance should be taken into account.

Common control parameters include temperature (usually within a narrow range specific to the cells), pH (maintained at an optimal level for cell growth and metabolism), dissolved oxygen (to support aerobic respiration), and agitation speed (to ensure proper mixing and oxygen transfer).

Monitoring should be done frequently, especially during the initial stages of the culture and when critical changes are expected. Typically, parameters like pH, dissolved oxygen, and cell density are checked at least several times a day.

Some manufacturers offer customizable options, allowing you to add or modify features such as sensors, control systems, and vessel size to suit your particular research objectives.

Always follow proper laboratory safety protocols. Ensure electrical connections are safe, handle chemicals and biological materials with care, and be aware of potential hazards related to pressure build-up or gas leaks.

Cleaning typically involves removing all residues, followed by sterilization using methods like autoclaving, chemical sterilants, or irradiation, depending on the materials and the nature of the cells being cultured.

You can collect data on cell growth kinetics, metabolite production, changes in pH and dissolved oxygen over time, and other parameters relevant to your specific research question. This data helps in evaluating the success and efficiency of your experiments.
