Biomass monitor probes and bioreactors incorporating such probes

摘要

A bioreactor arrangement has an enclosure (2) and an impedance monitor probe. The enclosure (2) is for containing a biological medium and includes one or more elongate port extensions (3) projecting outwardly from the enclosure and communicating from the exterior to the interior of the enclosure. The impedance monitor probe (11) is secured in one or more of the elongate ports (3) in order to have an electrode arrangement positioned (21a,21b) for monitoring of the biological medium. The impedance monitoring probe (11) comprises an elongate housing (13) having an outer surface extending along and contiguous with the elongate inner surface of the port extension. Housing extends from the electrode end (14) of the probe (11) to the remote end (16) of the probe. The remote end (16) of the probe is provided with an opening (29) of a bore (17) which extends at least part way internally along the length of the elongate housing (13) to an electrical connector (19) connected to the electrode arrangement.
