Models CF1 and CF2

The CF models homogenize cell suspensions continuously with the principle of high pressure relief (known as French-Press-principle). In a free selectable pressure range up to 2700 bar (40 kpsi) all kind of cell suspensions are processed and efficiently disrupted: bacteria, yeast, algae, mammalian and insect cells, fungus etc.. Even at the highest pressure proteins are not denatured, that is why this technology is very beneficial and mostly used for protein isolation. This model is designed for applications in research, development and analytics.


The model CF1 with 1.1 kW compressor power is the smaller table variant and processes sample volumes at a speed of 100 ml/min. Automatic sample supply and hydraulic cooling are optionally available.

For processing even larger volumes, the free-standing model CF2 is available with a process speed of 400 ml/min (24 l/h) and a compressor output of 4 kW.


Viscous samples need the alternative HAIVA model option, which can be built in all four compression versions. These systems have disruption head with an enlarged inlet area for clumpy or high viscous samples, e.g. filamentous fungus or plant cell cultures.
