Leírás és Paraméterek
Photobioreactor PBR-5.4 is an autoclavable glass / stainless steel photobioreactor with vessel volume of 6.2 L (working volume 2 – 4.5 L, inner diameter – 150 mm).
Laboratory bioreactor PBR-5.4 is devised for precise phototrophic cultivation of algae and cyanobacteria.
Bioprocess controller BIO-4
In the bioprocess controller BIO-4 are included: colored 5.6” touch screen interface display, thermostat, peristaltic pumps, LED cover, illumination control, air and СO2 gas supply unit.
Bioprocess controller BIO-4 ensures:
-
Control of pH, pO2, illumination (LED) intensity, temperature, foam and culture level
-
Display of the process data (temperature, pH, pO2, illumination intensity etc.)
-
CO2 supply via automatic pH control or manual CO2 gas flow rate control
-
Illumination intensity control – 0 to 100% (0 to 1500 µmol/m2/s)
-
Control of the illumination intensity as a time dependent profile program
-
Illumination day/night cycles
-
Remote control of the experiment via internet, real time data acquisition and plotting (SCADA Control System)
-
Thermoregulation (is carried out trough double wall bottom (jacket), with thermo-stating water circulation)
-
Both static and day/night temperature control is possible
-
Mixing (provided by mixer consisting of 2 propeller type turbines devised for shear sensitive microorganism cultivation
-
Addition of various substances (provided by peristaltic pumps for hemostat cultivation mode and fed-batch control (fed-batch control constant or pulse).
Extension and option possibilities
Gas mixing using mass flow controllers Hamilton ARC pH and DO sensors. These sensors send 4-20 mA signals directly to PLC and ensure at the same time information management via Bluetooth in smartphones or PC installed programs. This program generates a report about all calibration procedures, sterilization numbers, predicted service life.
Connection of additional sensors: culture turbidity (optical density), culture permittivity (viable cell density), conductivity, methanol/ethanol, off-gas analysis (O2, CO2, CH4), etc.
On-line/off-line data analysis and advanced process control possibilities using PC implemented program (Matlab, Python) algorithms communicating to process control system (PLC and SCADA).
