LAMBDA Fermentor Minifor

The Minifor was developed as a result of the need to construct a small laboratory fermentor for volumes from 0.035 to 4.5l.
Based on long personal practical experience in fermentation we wanted to create a laboratory fermentor, which was easy to use and with the capacity to measure and control all the important parameters of the biological culture.
The fermentor had to take up minimum space on the bench but with a good access to all parts.
Several laboratory fermentors should, when placed side by side be suitable for the optimisation of the parameters of growth of culture or optimisation of biotransformations etc.
Each fermentor should be able to work independently or be connected to a PC for advanced regulation and extensive data treatment.
Collects fractions in any racks of your choice
Collects unlimited number of fractions
The electronics and moving parts are placed above the tubes
– No damage due to spilling
Can be placed in a cold bath or any other thermo-stabilized container
Unlimited number of programmes
Extremely easy programming of rack and tube position by means of a white pen
Fractionation according to time (0.1–999.9 min and 1–9999 min) or volume (0.05–500 ml or 0.1 to 30 l)
Good quality for a fair price
Solvent resistant construction
Tubes easily accessible from all sides
Pause (from 0 to 999.9 min and 1 to 9999 min) or rinsing can be programmed between fractions
Up to 18 fractions simultaneously; multi-channel operation (optional)
Collection in lines or zigzag (meander like)
RS-232 interface (optional)
Practical, precise and reliable pumps - the most compact in their class.
Flow rates from 0.01 to 10’000 ml/hour
Large digital speed setting range from 0 to 999
New motor technology
Extensive remote controls
Greatly extended tubing life with decreased pulsation
Flow rate programming (up to 99 steps) and
automatic switch-on and -off without using any timer
Very economic in use; virtually noiseless operation
Most compact pump of this type on the market
Access to reaction kinetics by using the Pump-Flow INTEGRATOR
Low voltage plug-in power supply for maximum safety
RS-485 interface (optional)
Control software PNet (optional)

The special mechanics of LAMBDA peristaltic pumps has been developed because no pump could be used for continuous fermentation lasting up to eight weeks.

New syringe fixing system “VIT-FIT” allows almost any syringe to be used without adapter (from micro-syringes to large volume syringes of 150 ml and more)
The syringe is tightly held in both directions – infusion and filling
Highest mechanical stability allows for high pumping forces and precise flow rates without pulsation
Programmable (99 steps for infusion and filling)
Very easy handling of the syringes
Swiss quality motor and ball screws
Two valve outputs
Remote controls
RS-485 interface (optional)
Control software PNet (optional)
For automatic or continuous addition of solids, powders, crystalline substances, nano-materials and nano powders without a spoon
Dosing speed range from 0 to 999
Reproducible dosing flow rates (e.g.
50 mg/min to 50 g/min for NaCl)
Programmable
Easy assembly and cleaning
Necessary to comply with GLP requirements and safety standards
Hermetic construction allows operation in controlled atmospheres (Ar, N2,…)
Safe handling of dangerous and toxic substances
Remote controls
RS-485 interface (optional)
Control software PNet (optional)
Allows the control of pH of cell cultures by controlled addition of gaseous CO2, N2
or any other gas with a suitable controller
High-quality laminar mass flow sensor with minimal pressure drop
Can be used independently - all functions accessible from the front panel
Flow rates from 0 – 500 ml/min or 0 – 5 l/min
Flow rate regulated by a proprietary proportional
needle valve controlled by a microprocessor
Linearity error less than ± 3 % reading (which is
much better than precision expressed as percent of full scale used by some producers)
Repeatability better than ± 0.5% reading
Programmable flow rates
Flow volume can be recorded with INTEGRATOR
RS-485 interface (optional)
Control software PNet (optional)
Control of pH during chemical reactions where the pH is controlled by addition of acid or base
(hydrolysis of esters, amides, anhydrides etc.)
Measurements of enzyme activities of numerous
enzymes (esterases, acylases, lipases, proteases
and others using a pH-stat)
Control and quantification of metabolical activity of cells during fermentations and cell-cultures (by
control of pH, rH, pO2, pCO2, conductivity or other required parameter)
Recording of foam formation (automatic addition of antifoam agent)
Recording of addition of reactives during exothermic reactions with addition of reactive controlled by a thermostat
Recording of consumption of reactives during titration making of gradient for gels, chromatography etc.
