Compact fermentor system with smallest footprint



The footprint of the MINIFOR fermentor-bioreactor system is similar to an A4 sheet of paper.

The compact construction of MINIFOR fermentor and bioreactor was made due to the fact that the costs of laboratory bench-space are extremely expensive which is completely ignored.

The control tower and the complex cable connections are completely eliminated by placing the microprocessor controlled control unit just below the fermentation vessel. The control unit contains several cables, connections, tubings as well as the heating source which makes the working environment less complex.

Due to this innovative technique, the footprint and dimensions of the fermentor-bioreactor are highly reduced and making them more convenient to work in the lab as well. The space requirement of the MINIFOR fermentor-bioreactor with working vessel and the control unit is: 22 cm x 38 cm x 40 cm (W x H x D). Because the sealed, watertight control unit also serves as a stable holder for vessels of all working volumes, quality peristaltic pumps, storage bottles for acid, base/nutrients and the smallest antifoam control unit.

Despite being compact, the connections are easily accessible: the side necks for the probes and ports are constructed at an angle of 30°. The gained space allows easy and perfect sterility maintenance.

It spares time and energy spent on setting up the connections and dismantling them for each experiment!

Critical process parameters control (CPP)

LAMBDA MINIFOR fermentor and bioreactor can be fully controlled and operated from the front panel. Together with the probes, controllers and pumps it forms an autonomous unit. All parameters can be immediately seen without scrolling and can be adjusted from the front panel.

Each control unit has its own two microprocessors and complete regulation electronics to ensure a continuous measurement, immediate response and the control of all process parameters. All the parameters (temperature, pH, pO2, air flow rate, DO, agitation and a free selectable parameter e.g. pCO2, optical density, antifoam etc.) set and actual values as well as the high and low-alarms are visible at a glance on a large LCD back light display (4 x 40 digits). The controls are simple and logical.

LAMBDA delivers high quality bioreactors and fermentors, where each vessel has a complete and totally independent measurement and digital control system with all data on a large display.

Never having to worry about leaving a working vessel unattended with the precise parameter regulation!


Accessibility and visibility

All the electronics, power supply, IR heater, air valve, mass flow meter and cables are conveniently placed in the base unit, which is also used as a support for a fermentation vessel and all other necessary equipment. The platform arrangement of the base unit makes all parts of the fermentor clearly visible and easily accessible from all sides, despite the base dimensions of only 22 x 40 cm (approx. an A4 sheet of paper).

The LAMBDA bioreactor is constructed like a stairway to allow the best visibility, optimal access to all parts, minimal connection distances and location of all components in logical place:


The arrangement and distribution of all the important elements and functions to a minimal space under and around the vessel brings an extreme economy of the very expensive laboratory bench surface.

Compact and quality instrument for laboratory

People often ignore that the lab bench-space is the most expensive surface in the world. The laboratory fermentors and bioreacors should occupy a minimal bench-space with convenient handling, workflow and maintenance. LAMBDA offers the most compact fermentor/bioreactor with no compromise to quality!

Compact fermentor & bioreactor



“Watch your MINIFOR because this compact and handy fermentor can be carried away by a single person!”

MINIFOR occupies only the size of an A4 paper in the laboratory bench-space!

Although LAMBDA MINIFOR takes only a minimal laboratory bench surface, the connections are easily accessible: the side necks for the probes and vessel ports are arranged at an angle of 30°. Sterile handling is made simple and perfect with LAMBDA easy sterility concept.

Parallel running experiments



“The MINIFOR fermentor-bioreactor is not only a solitary worker. You can also let it work in a team, in parallel cultures, without loss of independence in parameter regulation.”

Unlike conventional systems, the MINIFOR units do not need to be placed next to each other during parallel processes, but can be distributed across your labs.

Each MINIFOR unit has its own console which regulates all parameters locally and shows at a single glance the actual and set values as well as high and low alarms of each parameter.

Several MINIFOR units can be connected to one PC and the optional software allows remote control and data processing. For connecting multiple MINIFOR fermenter-bioreactor units to the PC no additional software licenses needed.

Modular MINIFOR system



“In addition to the standard 1 L vessel we can also supply 0.3 L (with a minimal working volume of 35 ml), 0.4 L, 3 L and 7 L reactor vessels. The vessels can be replaced easily and at low cost. What else can we do for you?”

MINIFOR adapts to the requirements and not vice-versa.

Each MINIFOR unit has its own measurement and control electronics for all parameters (pH, pO2, temperature, agitation, aeration rate and one additional selectable parameter). Based on the project, additional modules or accessories (other vessel volumes, pumps, integrators, mass flow gas controllers, software…) can be selected any later, which make the acquisition costs low.
