MINIFOR
Build up your own fermentor / bioreactor

Questions

• Working volume range?

  Which vessel would you like for your fermentation kit?
  Since the vessels are easy to exchange, you may also choose different vessels for just one fermentation kit.
  Tips: Small vessel = better control = better result. Vessel i continuous mode = up to 10 × volume

  Vessel volume	0.035l	0.4l	1l	3l	7l
  min. working volume [ml]	35	100	300	1000	2000
  max. working volume [ml]	500	500	1200	2300	6000

• Operation mode: Batch, fed-batch, continuous, perfusion?

  How many feed and / or harvest pumps do you need?
  Which flow range do you need?
  (The LAMBDA peristaltic pumps can also be used as stand-alone instruments.)

  	PRECIFLOW	MULTIFLOW	HiFLOW	MAXIFLOW
  Flow rate [ml/hour]*	0–600	0–600	0–3000	0–10000
  Programming	No	up to 99 steps	up to 99 steps	up to 99 steps
  Power [max. W]	5	5	30	60
  Weight [kg]	1.2	1.2	1.5	1.6

  * Tubing made of silicone or other material with similar elasticity (internal diameter 0.5 to 4 mm, wall thickness ~ 1 mm). Programming is important only if the pump is used as a stand-alone instrument.

• pH-control

  Do you need to control the pH by base? and / or
  Do you need to control the pH by acid? or
  Do you need to control the pH by CO₂?
  Dou you need to know the amount of base and / or acid added to the broth as a function ot time?
  The software of each MINIFOR offers all possibilities. But you choose, if you need the pumps (LAMBDA PRECIFLOW) and / or MASSFLOW for the parameter control. The added tools can also be used as stand-alone instruments for other laboratory tasks. You may also order the MINIFOR without additional tools and add them later according the technical specification of your project.

• pO₂-control or gas flow control

  Do you need the pO₂ probe for the measurement of dissolved oxygen?
  Do you need to apply a gas-mix?
  Do you need to know the amount of each gas added to the broth as a function of time?
  The software of each MINIFOR offers the pO₂ and the gas flow control. One MASSFLOW for aeration is already incorporated to the MINIFOR. But you choose, if you need pO₂ probe and / or further MASSFLOWs for the gas-mix. You may also order the MINIFOR without additional tools and add them later according the technical specification of your project.

• What is your required temperature range? – °C

  MINIFOR is equipped with a temperature probe (PT100) incorporated in the pH probe. Infrared radiation (IR) is used for heating. No hot surfaces are used and therefore no local overheating occurs. The IR allows a very precise temperature controls and even temperature shifts are controlled without overshooting the set point. The cooling system is optional: Cooling Finger (Peltier principle – no cooling water needed) or Cooling Loop (cooling water needed).

• Do you work with sheering force sensitive cells?

  MINIFOR is also a bioreactor and therefore it can be equipped with FISH TAIL stirrer plates instead of common stirrer plates. FISH TAIL creates low sheering forces but stays effective in mixing. The stirrer plates are included for each unit, but you may choose the type of your project.

• Do you need automatic foam detection and antifoam system?

  MINIFOR can be equipped with the optional ANTIFO and DOZITO, the automatic antifoam system with syringe pump.

• Do you need the data storage and/or remote control for the fermentor on your PC?

  (The MINIFOR is equipped with a control panel which shows all set-points, actual values and alert limits at one glance without scrolling. No PC and additional software is necessary to control the MINIFOR. In case of data storage, remote control and visualization / comparison of parallel running MINIFORs, the optional PC software is required.)

• Do you need other tools or functions?

• How many MINIFORs would you like to run in parallel?
