Bühler stirred-tank reactors are the flexible workhorse for industrial biotechnology. Designed for highly controlled fermentations and cell cultures across food, feed, and industrial biotech applications, STR systems provide maximum process control from lab to large scale. With efficient gas dispersion, advanced agitation, and integrated automation, they give you the freedom to run a broad range of organisms and process modes reliably.

Bühler bubble column reactors use gas injection from the bottom to mix and aerate the fermentation broth without an internal agitator. This simple, robust design is ideal for large-volume, aerobic processes where low mechanical complexity, high uptime, and cost-effective operation are key. Column geometry, gas distribution, and internals are tailored to your organisms and process targets.

Bühler airlift reactors use gas injection in a riser section to drive circulation through a loop or draft tube, creating well-defined flow patterns without a mechanical agitator. This design combines low shear, good circulation, and efficient gas–liquid contact, making airlift reactors an excellent choice for sensitive organisms and energy-efficient operation.

Bühler jet loop reactors use high-velocity liquid jets to create strong circulation and fine gas dispersion in a loop configuration. This delivers very high oxygen transfer rates and intensive mixing in relatively small volumes, enabling process intensification and high productivity where space and performance are critical. Jet loop systems are ideal for demanding aerobic and intensified bioprocesses.
