The very expensive, clumsy and complex to set up traditional metal head plates were completely eliminated and replaced by new threaded glass vessels.
The vessels are made of high quality Pyrex glass with one large threaded central opening for the fixation of the easy sterility membrane and vibro-mixer.
The 8 threaded necks for the connection of different probes, air outlet, sample withdrawal, inoculation etc.
The threaded side necks allow unhindered access to all ports. Multi-seal permanent stoppers are easy-to-use and eliminate sealing problems.
The standard 1 L fermentation vessel has a working volume of up to 1.7 liter (other vessels with working volumes from 35 ml to up to 6 liters can also be provided).
*) Volume: Approximate minimal and maximal working volumes. The working volumes may vary according to the conditions of each application.
**) Height + Diameter: Approximate dimensions of the vessel for autoclaving with typical accessories. May vary according to the fermenter /bioreactor configuration and used accessories.
Several interchangeable vessel types allow growing cultures in volumes from 35 ml to over 6 liters with just one single instrument.
The ports for the probes are located in such a way that the same probes can be used in any vessel volume. This makes a considerable economy when compared with bioreactors of other producers.
An adjustable holder maintains the vessel in position. With the exception of inexpensive lateral vessel holders and stirring axis all other parts can be reused, when working with different fermentation vessel sizes.
