Spargers for Bioreactors

Air Sparger In Bioreactor

Bluslot focuses on the development and production of spargers in bioreactors.
Why use the air sparger in the bioreactor?
In large bioreactors, due to surface area limitations, the gas does not bond sufficiently to the material, which can lead to the accumulation of carbon dioxide and prevent the permeation of oxygen. Introducing oxygen through a sparger to remove carbon dioxide is the best solution.


Micro Spargers for Bioreactors

Mammalian cell bioprocessing, biofermentation, aeration, bench top bioreactors. Regulating oxygen and carbon dioxide levels in bioreactors.



Stainless steel, Titanium, Inconel, Monel, Nickel, Hastelloy, Special material. Bluslot can customize special raw materials according to customer requirements.



Reduce gas consumption and operating costs. Wide range of applications. The precision of the aperture is well controlled. Acid and alkali corrosion resistance.



Bioreactor Sparger Specifications

The mass transfer effect of gases such as oxygen and carbon dioxide is an important element in bioreactors. The stainless steel porous filter air spargers developed by Bluslot greatly increase the mass transfer rate. The gas sparger converts the gas flow into millions of tiny air bubbles and feeds it into the reactor vessel. The contact area between the gas and the liquid will be greatly increased, and the mass transfer rate will be optimized most efficiently. Our design features are easy to replace and reduce product operating costs.

Service for Sparger In Bioreactor

Bluslot’s patented product – a micro sparger, can better reduce the size of bubbles and increase the gas transmission efficiency. Gas consumption is also reduced, increasing reactor output. Our patented products work 40% to 80% more efficiently than comparable products on the market.

Free design

Bluslot® has a technical team of more than 30 people, in addition to the continuous research and development of new products, it can also provide customized services for customers. Finally, 3D drawings will be issued for customers to confirm, that this service is free.

Lab testing

We have on-site use simulation labs. To ensure the usability of the product, we test it before leaving the factory. In the end, we will upload the test results to our system and give them to customers for reference.

Product testing

Our product inspection system is independent of the production department. From raw material selection, production process, and surface treatment to packaging, we have a complete quality inspection system. Our quality inspection department and after-sales department cooperate with each other, if your product has any quality problem, we will exchange it for free.

Big Data

Unlike other bioreactor air sparger manufacturers, we begin collecting market end-use data on day one. We now have a large amount of usage data, which can not only help our technical department to upgrade products but also provide customers with the most professional product usage guidance.

The technology of Sparger In Bioreactor

Quick Change Spargers for Bioreactors and Fermentors

Product structure. Porous metal and connecting components make up the simplest product. The specification parameters of porous metal and the shape, size, and type of connecting components can be changed to customize products, which can be applied to different equipment. The porous metal structure is strong and does not require support parts. Wire mesh sintered filter elements can also be used in special environments instead of porous metals.

Bluslot Porous Metal Spargers

The easiest and most efficient method of oxygen transfer is to inject the gas directly into the system. Bluslot’s products provide uniform bubble and dispersion rates.


The sparger must overcome the influence of acid-base corrosion and high temperature. Our raw materials: 316L, 347 SS, 904 SS, Monel 400, Nickel 200; Hastelloy C276, C22, and X; and Alloy 20.
