In addition, up to 8 peristaltic pumps for different chemostat cultivation control can be linked to the Photobioreactor FMT150 for the highly precise control of cultivation conditions.
3 DEVICE DESCRIPTION Standard version of the Photobioreactor FMT150 consists of a cultivation vessel with a sealable lid and a base box containing electronics circuitry, LED light panel (Fig. 1A) and other components essential for the optimal operation of the photobioreactor.
FMT150 can be shipped with various configurations of vessel capacity, light quality, light intensity and thermoregulation. Numerous additional accessories such as various sensors can be supplied as described in chapter 5 on page 33. Please note that this manual describes operation of two FMT150 versions (Fig. 4) - older PBR FMT150.1 and new PBR FMT150.2.

The FMT150 in both 400 and 1000 ml models have been upgraded from FMT150.1 (Fig. 4A) to FMT150.2 (Fig. 4B). This manual provides instructions for operation of both versions (original, now referred to FMT150.1 and the current version FMT150.2). Please always ensure that you refer to correct instructions.
PBR software no measured data can be stored and visualized as well as no user- defined protocols can be designed. Chapter 3.3 and chapter 7.1 describe how to operate the PBR FMT150 in cultivation mode via front panel control unit, without use of PBR software.
Please note that neither turbidostat nor chemostat module can be operated if FMT150 is purchased without the PBR software. The front panel of the FMT150 control unit has 4 LED lights on the left and 5 control keys on the right (Fig. 7).

IDENTIFICATION LABEL WITH SERIAL NUMBER Each Photobioreactor FMT150 has a serial number that corresponds with the serial number of the power supply unit. These are always provided together and are not interchangeable. Prior to switching PBR FMT150 device ON make sure that the serial number on the front panel of the main body matches the serial number on the power supply (Fig.
Depending on the use of optional modules and the set-up of the PBR FMT150, the connection schema for the optional and standard modules with the PBR FMT150 control unit rear panel may differ. Please refer to Tab. 5 below to see the possible order of connecting the different modules to the PBR FMT rear panel.

FMT150, calibration constants stored in the system after OD calibration will no longer correspond to the new conditions. In 1000 ml or 3000 ml PBR FMT150 version glass tunnel is used to improve optical path for OD and fluorescence measurements, therefore any shift in the position in the vessel might slightly change the optical path of the measuring beam and influence the absolute measured values.
