Unpack and get started

The Minifors 2 will take you directly to your bioprocess. The bioreactor is preconfigured and delivered ready to use. Connect the device, mount the vessel, connect pumps and sensors and begin to work after only 10 minutes.

Award-winning design for practical applications

The Minifors 2 has a compact, user-friendly design. With its small footprint and few external connections, the bench-top bioreactor takes up little space in the lab. Your work around the bioprocess will be simplified by special details; for example, the practical vessel holder that enables the safe and risk-free transport of the pump heads and the bottles together with the culture vessel. Also, the steel drip tray can be easily cleaned, even if the bioreactor is in operation.

It speaks your language

Easy and intuitive means: Get on directly with the bioprocess in only a few steps thanks to understandable controls and without the need for training. The touch screen accompanies you through the experiment in several languages. You can prepare everything in the shortest possible time – from the calibration of the sensors to the configuration of cascades and specification of setpoints.
