Stainless steel bioreactors are not a new technology, and they have been in use for several decades. However, with the introduction of single-use bioreactors, they are no longer the first choice for biomanufacturing. The lower starting cost for a single-use bioreactor is the prominent reason behind this. But is it the end for stainless steel bioreactors? Will this equipment lose its value in 2026 and in the years to come? Well, the straightforward answer to both of these questions is No.
While single-use bioreactors are more cost-effective and faster, they still fall short in terms of large-scale production. When it comes to industrial-scale production, the capabilities of stainless steel (SS) bioreactors exceed those of single-use(SU) bioreactors by a significant margin. That is why the SS bioreactors are still preferred over SU bioreactors in multiple scenarios. If you are debating whether to invest in stainless steel bioreactors or not, use the following question to base your decision.
Check Out the Top 7 Questions Before Buying a Stainless Steel Bioreactor
Here are the crucial questions to consider before purchasing stainless steel bioreactors in 2026.
1. For what applications can you use a Stainless Steel Bioreactor?
Stainless steel bioreactors are versatile equipment and are used in manufacturing a wide range of products. Industries such as food and beverage, agriculture, biomanufacturing, and pharmaceuticals extensively utilize these bioreactors. Let's take a brief look at the applications of the stainless steel bioreactor in each industry.
Pharmaceuticals: This industry utilizes stainless steel bioreactors because of their ability to provide a controlled environment for cell growth. Therefore, the pharmaceutical industry utilizes them to synthesize vaccines, proteins, and active pharmaceutical ingredients (APIs). Using bioreactors in this industry ensures the production of high-quality drugs and medicines that are rapidly absorbed by the body.
Food and Beverage: Stainless steel bioreactors are crucial for different types of fermentation processes. Their ability to control the parameters of the fermentation process helps in the production of numerous food and beverage items. From beers to dairy products, the food and beverage industry utilizes stainless steel bioreactors for bulk production.
Biomanufacturing: Bioreactors are primarily used to control cell culture growth and enhance the growth process with a constant nutrient supply. Consequently, the reactors are used to manufacture biofuels and other biopharmaceutical products. In addition to production, stainless steel bioreactors play a crucial role in biotech research.
2. How can a Stainless Steel Bioreactor Impact Production Quality and Capacity?
Bioreactors, particularly stainless steel bioreactors, have a significant impact on production quality and capacity. The pharmaceutical and biomanufacturing industries utilize bioreactors to enhance the quality of their products. With the help of a stainless steel bioreactor, you can control every parameter related to the cell's growth. The controlled environment and ideal cell growth conditions ensure the synthesis of a high-grade, uncontaminated product. Consequently, proteins, enzymes, biofuels, and other bio-products manufactured with stainless steel bioreactors are of superior quality.
In addition to quality, stainless steel bioreactors also impact industrial production capacity. In fact, industries systematically use these bioreactors to increase their production capacity. A stainless steel bioreactor has a capacity ranging from 10 L to 20,000 L. In comparison, the single-use bioreactors can only hold up to 2,000 L to 5,000 L at max.
3. Why are stainless steel bioreactors ideal for Pilot & Large-scale Industrial Production?
Whether it is Pilot industrial-scale fermentation or manufacturing drugs and bioproducts in large quantities, stainless steel bioreactors are an ideal choice. The following points will explain why:
These bioreactors are contamination-free and corrosion-resistant. Therefore, you can use them with different products after cleaning and sterilization.
With stainless steel bioreactors, it is possible to scale up production without incurring additional expenses.
Due to the use of high-quality materials, stainless steel bioreactors have a long life and are quite durable. That is exactly why, despite a high initial cost, stainless steel bioreactors prove to be cost-efficient in the long run.
4. Are Stainless Steel Bioreactors an outdated technology?
As we said before, the popularity of newer single-use bioreactor technology does not imply that stainless steel bioreactors are outdated in any sense. They are still widely used across multiple industries and remain the preferred choice of many manufacturers. Also, the stainless steel bioreactor itself is evolving with time and has incorporated many modern features. So, it is not correct or factual to say that stainless steel bioreactors are outdated.
5. What are the primary benefits of a Stainless Steel Bioreactor Over a single-use bioreactor?
The choice between stainless steel and a single-use bioreactor can have a significant impact on your future plans. Whether to invest time and money in a stainless steel bioreactor or to quickly set up a single-use bioreactor depends on your specific needs and requirements. But if you are leaning more toward the stainless steel bioreactor, here are some of the primary benefits that you will get:
Reusable Bioreactor after Cleaning and Sterilisation: Stainless steel bioreactors are reusable and have a long operational lifespan. This means that you can reuse the bioreactors repeatedly for production and manufacturing purposes. However, it is advised to thoroughly clean the bioreactor to reduce the risk of cross-contamination.
Conveniently Increase the Production Scale: Once you set up the stainless bioreactor, you won't have to worry about the costs associated with upscaling production. However, increasing the production scale is quite challenging with single-use bioreactors.
A durable solution for high-pressure processing: Stainless steel bioreactors are robust enough to handle large-scale production. They are designed to withstand high-pressure conditions while ensuring consistent production.
No Risk of Plastic Contamination: The use of plastic in single-use bioreactors poses a great risk to extractables. Plastic from these bioreactors can contaminate the cells. Meanwhile, the steel vessel of the stainless steel bioreactors prevents contamination, ensuring high-grade production.
Lower Operating Cost: Although the initial cost of setting up a stainless steel bioreactor is high, it saves you a significant amount of money in the long run. The operating cost of stainless steel bioreactors is lower than that of single-use bioreactors.
6. What is the role and cost of CIP and SIP in Stainless Steel Bioreactor Maintenance Process?
CIP, or Clean-in-Place, and SIP, or Sterilisation-In-Place, are both crucial processes for the consistent and accurate working of a stainless steel bioreactor. When a batch is complete in the bioreactor, thorough cleaning and sterilization ensure that the new batch is safe from any contamination from the previous batch. The role of the CIP and SIP process is to provide the latest batch with a neutral environment.
However, CIP and SIP processes can be time-consuming and require complete efficiency. Any kind of carelessness can damage the product or reduce its quality. For this reason, industries use expensive machinery and procedures for these processes. The CIP and SIP processes are costly, and during the process, the bioreactor cannot be used for another batch, resulting in increased downtime.
How Many Types of Products are you going to manufacture?
With the increased production capacity, you may think that stainless steel bioreactors can handle multiple products, but that is not the case. The product changeover process with stainless steel bioreactors is complex and requires complete cleaning before proceeding. As we discussed earlier, it takes a significant amount of time and effort to clean and sterilize the bioreactors after completing a batch. Therefore, it is not productive to frequently change the batch type and spend considerable time on the screening process.
Wrapping it Up!
Stainless steel bioreactors are far from being replaced with single-use or any other type of bioreactor. They are still being used in modern bio-products and pharmaceutical product manufacturing. Stainless steel bioreactors have a higher initial cost and require a longer setup time. However, their scalability and durability are still significantly better than those of single-use bioreactors. The choice of which bioreactor to use depends on your particular requirements and future goals as a manufacturer. Picking the right bioreactor is associated with enhanced operational efficiency and yields superior-quality products.
