Stainless Steel Bioreactor LSSB-B10

Labtron Stainless Steel Bioreactors are designed with both efficiency and precision in mind. These bioreactors are made using high-quality stainless-steel materials (typically SUS316L for the tank and SUS304 for the jacket), ensuring durability and corrosion resistance. They come equipped with features such as a sight glass for easy monitoring, automatic air control, defoaming electrodes, and advanced sensors for measuring pH, DO (dissolved oxygen), and temperature. The bioreactors also have a jacketed water bath with circulating pumps for even heat distribution, ensuring stable and consistent temperature control. These features make Labtron bioreactors reliable tools for fermentation processes across a wide range of industries like pharmaceuticals, food production, agriculture, and scientific research.

Labtron uses a jacketed water bath system to manage temperature in its stainless-steel bioreactors. This jacket surrounds the main fermentation tank and is connected to a circulating pump that keeps water flowing continuously. This setup allows for even and consistent heat transfer throughout the tank. The system is electrically heated and includes Pt100 sensors, which are sterilizable and software-calibrated for precise temperature readings. The controller uses advanced PID (Proportional-Integral-Derivative) technology to maintain the desired temperature range, which can be set between +5°C above the cooling water and up to 50°C, with high accuracy (±0.5°C). This ensures optimal conditions for microbial or cell growth during fermentation.

Labtron bioreactors use a top-mounted mechanical stirring system designed for stable and efficient mixing. The system includes a precision-balanced shaft made of a special alloy for long-lasting performance. It operates with a 3-stage blade design one quadriclinal blade and two six-flat blades—which helps create thorough mixing and enhances oxygen transfer within the fermentation medium. The speed is adjustable from 30 to 418 rpm with high accuracy (±0.5%), allowing users to fine-tune the mixing process based on the specific requirements of the biological culture. This robust and flexible mixing setup is essential for maintaining homogeneity and promoting healthy microbial or cell growth.

Sterility is critical in fermentation processes, and Labtron bioreactors are designed to meet this need. The bioreactors support online steam sterilization (also known as SIP Sterilization In Place), allowing the tank, filters, and connected lines to be sterilized without dismantling. The internal surfaces are mirror-polished to a smoothness of Ra < 0.4 µm, reducing the risk of contamination from residues. The tank bottom is designed without dead corners and includes multiple sterilizable valves, such as a fermentation bottom valve and a discharge valve. Exhaust systems include condensers and separate sterilization/fume discharge units to handle waste gases safely. Combined with alarms, data logging, and automatic controls, these features ensure both sterility and operator safety.

Labtron Stainless Steel Bioreactors are highly versatile and find applications across several major industries. In the pharmaceutical industry, they are used for producing antibiotics, enzymes, vaccines, and recombinant proteins. In the food and beverage sector, they assist in the fermentation of products like yogurt, alcohol, and probiotics. In agriculture, they help in the production of biofertilizers and biopesticides. They are also useful in the energy sector for the development of biofuels and in scientific research for studying cell behavior and metabolic processes. Thanks to their precision, control systems, and scalability, Labtron bioreactors support both small-scale R&D and large-scale industrial bioproduction.
