RALF trio
triple RALF setup

The BioEngineering Roundbottom Autoclavable Lab Fermentor is a high quality Swiss manufacutered modular labscale bioreactor / fermentor. It can be used as a stand alone or in parallel use (up to 6 units per contol PC).

RALF can be configured for Microbial use or cell cultivation processes. Also many levels of automation are available, so it is always possible to configure your RALF specifically for your process e.g. gasflows, manual or MFC controlled liquid pumps with On/Off control or speedcontrolled drives and various (3rd party) sensors/probes can be fitted
