Maximal accessibility and visibility

More about perfect bioreactor accessibility and visibility

There has always been a big accessibility problem in small volume laboratory bioreactors.

The LAMBDA bioreactor was constructed like a stairway. This allows the best visibility, optimal access to all parts, requires minimal connection distances and all components are located on their logical place.

The display with pressure keys was placed in front of the vessel on the place where it is best seen. The user will see the state of the culture by just one glance. All measured values, all preset values, all alarms, the measured values and pump activity are displayed. It is important that the user does not need to scroll to be able to see the whole information.

The vessel is located on the "first step" behind the display. Here maximal visibility from all sides is provided. The access to the probes, ports and connections have been solved by a new vessel design. Side necks distributed around the vessel give an easy accessibility to all parts of the vessel.

The connections for probes and the stirring are placed between the first and second step, just behind the vessel. Like this, the cable distance is shorter and the cable order logical and is not mixed with tubing coming from the reagent bottles.

The reagent bottles with their magnetic holders are secured in place on the "second step" behind the fermentation vessel. The magnetic holders give the maximal freedom for the placement of bottles of different sizes and number on the smallest possible surface.

The "third step" are adjustable supports for the peristaltic pumps placed above the reagent bottles. This gives the shortest possible distance for the tubing between the bottle, the peristaltic pump and the culture vessel. Additionally, the activity of the pumps (speed and state) can be seen immediately.

The arrangement and distribution of all bioreactor elements and functions (which in all competing bioreactors are placed in big towers aside the vessel) to a minimal space under and around the vessel brings an extreme economy of the very expensive laboratory bench surface. We are convinced that it is not possible to construct a more compact bioreactor for this large vessel volume range, starting from few tens of milliliters to over 5 liters of working volume, with such a good accessibility from all sides!
