MRAR Scientific & Laboratory Division

Very gentle mixing with new Fishtail stirrer

Adapter for very sensitive cells

Culture volumes from 35 ml to 6000 ml

MINIFOR is very compact

Fully automatic gas flow

Automatic pH and pO2 control

Self-cleaning gas microsparger

All these features result in a dramatic improvement of the cell culture, precise control of preset parameters and their easy documentation.

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.
