Single and Parallel Autoclavable Stirred Photobioreactor

ELARA ST is a stirred jacketed photobioreactor ideal for phototrophic organisms such as Moss, Microalgae, Bacteria and plant cells.
The fully removable light module allows to use Elara as a traditional fermenter/bioreactor.

Solaris ELARA ST Features and Benefits

4 L total volume borosilicate glass vessel, 3:1 H/D ratio.
Different configurations available, with the choice of Rushton/Marine/Pitched-Blade impellers, and Toro/Sintered sparger.
Wide range of measurement and control options, including temperature, pH, dO 2 , dCO 2 , redox, antifoam, level, conductivity, weight, cell density (viable cells).
Modbus digital sensors reduce background noise and guarantee quick response time.
Suitable for batch, fed-batch and continuous processes.
Compact and modular PLC-based PCS LEM_1 , with n. 4 built-in fixed speed Watson Marlow pumps. Variable speed pumps can be integrated as option.
Powerful and accurate (1 RPM) brushless motor.
Optional integration of up to 4 analog input/output connections, choosing between 0-10 V and 0-20 mA/4-20 mA (e.g. pumps or valves with power supply independent from Solaris electrical cabinet).
Different gas mixing strategies with up to 5 TMFC and/or solenoid valves.
Fully removable and cleanable glass jacket for improved heat transfer during autoclaving.
LEDA Sterile sampling system, which allows up to 180 sterile samplings per batch, is available as option.
Light module consisting of n.3 vertical bars with 6 white dynamic LEDs each; Each LED consists of four chips: n.2 dedicated to warm white light (2700 K) and n.2 for cool white light (6500 K)
LED total power: 180W; LED brightness: 6120 lm.
Automatic and manual control of light intensity and circadian cycle simulation.
The light spectrum is selectable, and the light intensity is dimmable from 0-100% up to 3000 μmol(photon)/m2.
