The volume will depend on the concentration of inoculum that you have, the strain, and the photobioreactor that you use.
In general terms, our photobioreactors make it possible to start cultures with small quantities of inoculum, in particular due to the precise management of light intensity.

A hose links the growth chamber to the carboy or harvesting tank. The gas and the harvest exit via this hose, called the overflow hose. Since the usable volume is almost the same as the volume of the reactor, there is an overflow effect when there is a supply of fresh medium. Therefore, if you put in new medium, for example 1 L, you will harvest 1 L of culture by overflow.

You can use two modes: semi-continuous (emptying then filling) or continuous (continuous liquid flow). You use peristaltic pumps to add the new medium, either manually or automatically. You enter the volume of new medium that you want to add. The harvest will pass through the overflow hose to fall into the carboy or harvesting tank.
Harvesting refers to microalgae mixed with their culture medium. The separation takes place after the harvesting stage and using other (centrifuge type) tools. We do not intervene in treatment solutions (post-harvesting).

For batch cultures, harvest your culture by emptying your reactor entirely at the end of your batch.

Yes, absolutely.

Training is provided by our microalgae project manager before you use the equipment for the first time. It can either be done on-site or remotely (video). It is divided into two parts: theoretical and practical training. The training content and duration can be adapted to your needs.
