Fermentor

Fraction Collector

Experience new concept of fraction collector and collect fractions in any racks of your choice and unlimited number of fractions in single or multiple fractions.

Omnicoll is the only fraction collector which can be programmed for any rack or recipients. All electronic and mechanical components have been miniaturised and placed in one moving part, which is placed above the fractions in order to avoid the danger of spilling. It is equiped with modern microprocessor system with several optical senzores used for collection of fractions according to time or volume. Solid metal construction makes Omnicoll insensitive to solvents. Extremely easy programming of rack and tube positron. The capacity can be increased many times by coupling of several lower parts of Omnicoll.

Integrator

Connected to the LAMBDA Peristaltic Pump and other LAMBDA instruments, the integrator will allow you to record how much liquid has been pumped as a function of time. It informs how much of the solution (acid or base for example) has been added to maintain a constant pH. This additional data will inform you about the kinetics of the process, its completion or even disturbances that have occured during the process. Obtaining of this information was not available until now.

Mass Flow Controller

A new mass flow controller system especially designed for use with Lamda bioreactors and fermentors. It allows control of the pH of a cell culture by controlled addition of gaseous CO2, the control of dissolved oxygen by regulation of the airflow or any other gas with a suitable controller. It can also be used independently, since all its functions are controlled from the front panel or using the remote control.

Peristaltic Pump

Result of twenty years of laboratory experience, which leads to the systematic elimination of the imperfections found in other pumps on the market. Precise, reliable and most compact pump in its class. Well-proved mechanics of this pump includes flow rate programming and allows user up to 99 steps of time, which allows the creation of any flow rate profile. The bearing of a larger diameter with glass beads has been used in order to reduce pulsation, friction and mechanical strain leading to better pump performance.

Powder Doser

The LAMBDA DOSER is a unique programmable pump for free-flowing solid substances. It allows the automatic or continuous addition of powders, powdery and crystalline substances without a spoon. Composed of a dosing unit coupled to a stepping motor controlled by modern electronics, allows constant and reproducible dosing even of solids which do not flow well. A remote controller allows the doser to be used in automatically controlled reactions.

Software

Fermentation Software

FNet is a software for monitoring fermentation and cell culture processes with the LAMBDA MINIFOR laboratory fermenter. Runs under Windows NT, 2000 and XP.

All the information (actual values, set points, graphs, alarms) of the fermenter is presented in the main window :

• Actual values like temperature, pH, pO2, air flow rate, amount of base and acid, and an additional parameter X which could be for example the culture weight for continuous processes, optical density or an online biomass concentration measurement.
• Set point values like temperature, pH, pO2, air flow rate, agitation, another parameter X and one feed with a peristaltic pump
• Scalable graphs: The user can choose the fermenter parameters he wants to display in function of time
• Ruler to read values on the graphs

Data archive:

The process data (temperature, pH,...) are stored in a text file. This file can be exported to most programs on the market for statistical treatment or reporting. More fermentation batches can then be compared for process optimization.

Process control:

• Remote control of the fermenter, all the set point values can only be changed from the PC
• Possibility to know the amount of base and acid added into the fermenter
• Profiles on all the set points like temperature, pH, pO2, air flow rate, agitation, parameter X or feed with a peristaltic pump (figure 3)
• Alarm management: The user can activate alarms for temperature, pH, pO2, air flow rate, agitation, parameter X.
• The program shows when an alarm has occurred.
