About...

Turbidostatic Module controls the biomass concentration (turbidity) via OD 680 or OD 720 in each vessel independently. The OD can be maintained at a constant level or within a preset range depending on the experimental aim.

Key Features

Special silicon stoppers with an additional port for medium fed in.
The flow rate of the peristaltic pump feeding in the medium runs between 0.2 – 50 ml/min and is adjustable for each test vessel independently. Just one medium reservoir for all cultivation vessels can be used.
Culture volume is kept constant by a passive medium overflow.

The module includes its own aeration pump that is more powerful compared to the standard air pump and thus can provide sufficient power to aerate the entire system properly.
The Photobioreactor Control Software must be ordered to operate the Turbidostatic module.

Turbidostat Module TS 1100

The Turbidostat module TS 1100 enables continuous-flow cultivation in the Multi-Cultivator MC 1000. In the basic setup, the Multi-Cultivator’s optical sensing unit monitors the optical density in each culture vessel and the Turbidostat module adds fresh medium to maintain a preset turbidity (OD) level independently in the individual vessels. The fresh medium is delivered by a peristaltic pump to each vessel at a different controlled flow rate through 8 independent pinch valves.

The turbidity of each culture vessel, and therefore biomass concentration of the organism, is controlled either through OD680 or OD720 measurement. The OD can be set to a constant level or set to change over a specific range. Number of various turbidostatic cycles are available and can be specified for a particular experiment. The peristaltic pump flow rate runs between 0.2 – 50 mL/min.

The pumping speed can be set for each culture vessel independently. Moreover, the new Turbidostat module TS 1100 accommodates its own Air pump to guarantee a sufficient air supply and mixing of the biomass in all test vessels.
