Photobioreactor

The BTP photobioreactor provides controlled conditions for:

• Light supply
• Temperature
• Nutrient supply
• Gas management

The scope of equipment is implemented according to customer requirements.

Of particular note is the advanced lighting supply and in-situ measurement technology for monitoring light irradiation in the bioreactor. For this purpose, LED light bars and an in-situ multi-channel sensor system are used.

The LED light bars have the following specifications:

• Red wavelength 670 nm, each with 15 LEDs; total power per module up to 1.5 W
• IR wavelength 740 nm, each with 15 LEDs with integrated visible control LEDs; total power per module up to 1.5 W
• Green wavelength 570 nm, each with 15 LEDs; total output per module up to 1,200 lm/2 W
• Blue wavelength 480 nm, each with 15 LEDs; total output per module up to 270 lm/3.6 W
• White color 2,700 K with 15 LEDs each; total output per module up to 825 lm
• Dimensions of each lighting module 300 x 15 mm – others on request

The LED lighting bars can be controlled individually, ensuring a very defined light supply. The number of modules/bars is determined individually for each reactor.

In-situ light intensity sensor

A light intensity sensor with 14 channels is available. This allows semi-quantitative measurement of light intensity. The following image shows the wavelength range and specifications of the sensor.
