Understanding Bioreactor Types

Bioreactors are vessels that grow microorganisms, tissues or cells in a controlled environment. They play a crucial role in producing pharmaceuticals and vaccines, as well as developing biofuels and food byproducts.

There are six common types of bioreactors on the market, and each offers unique features ideal for specialized functions.

Airlift Bioreactors

Airlift bioreactors contain a draft tube that may either be internal or external. This draft tube works to improve circulation and oxygen transfer in the bioreactor. Airlift bioreactors are ideal for use in the large-scale culture of plant cells.

Bubble Column Bioreactors

Like airlift bioreactors, bubble column bioreactors have tall, cylindrical columns filled with liquid. An aeration system at the bottom of the column produces bubbles that make them viable for the growth of microorganisms.

Continuous Stirred Tank Bioreactors

Continuous stirred-tank bioreactors are the most common type of bioreactor. They are widely used in producing chemicals and pharmaceuticals, as well as in wastewater treatments.

Fluidized Bed Bioreactors

Fluidized bed bioreactors are ideal for multiphase chemical reactions. It works by allowing a gas or liquid to pass through a solid material at high speeds, causing it to behave like a fluid. They are typically used to produce gasoline and other fuels. They are also common in chemical engineering and food processing industries.

Packed Bed Bioreactors

Packed bed bioreactors are commonly used in catalytic reactions and fermentations. Designed with cylindrical shells with convex heads, they utilize gravity to allow reactants to flow.

Photobioreactors

Photobioreactors convert sunlight into usable energy through photosynthetic organisms. This innovation allows the harvesting of energy for use in different applications.

How to Choose a Bioreactor for Your Needs

There are several bioreactor designs and types because they serve different purposes. Consider these requirements to determine which bioreactor to get:

• Workspace requirements: Bioreactor volumes can span from as low as 2 liters to as high as 50 liters. Pick one that fits your space and accommodates your needs.

• Material: Bioreactors are generally made from stainless steel, glass or single-use plastic to fit various project requirements. A stainless steel bioreactor vessel is great for pressurizing content. Glass tanks are ideal due to their transparency. Single-use plastic eliminates the need for cleaning and reduces the risk of cross-contamination.

• Cleaning: It’s extremely important to keep your bioreactors clean and sterile for every project. Look for bioreactors that make cleaning quick and easy.

• Costs: Bioreactors can be expensive, especially brand-new ones. If you’re just starting out or working on small-scale projects, consider sourcing used bioreactors to cut costs.

The Advantages of Opting for Used Bioreactors

Bioreactors, like other laboratory equipment, tend to come with a hefty price tag. However, opting for used bioreactors is a cost-effective and sustainable solution for sourcing high-quality technology.

Used bioreactors may have minor cosmetic issues, but they are still capable of delivering excellent results and often have long remaining service lives. You also help prevent them from going to waste while still in good working condition.
