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.
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.
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.

Frequenty Asked Questions

A photobioreactor is specifically developed for microalgae growth and it is therefore equipped with a light source. This light source must meet the microalgae needs in terms of radiation wavelength and intensity. It should as well be programmed to simulate a day-night cycle so that cellular processes are not compromised.

Microalgae are photoautotrophic unicellular microorganisms. It means they use light radiation to run photosynthesis and magically turn sunlight and carbon dioxide into oxygen and a bunch of other things. Single cells can gather in chains or other shapes. Microalgae offer a variety of metabolic products that are potentially appealing for the nutraceutical market.
