Higher Cell Viability
in Perfusion

 

Perfusion establishes the benchmark for high product yield. High cell viability and density should therefore be the major objective. Peristaltic pump systems cause cell damage due to mechanical stress of tube compression. Furthermore, these systems bear the risk of a catastrophic tube rupture due to a possible pressure build-up or tube wear.

Levitronix® pump systems are designed for demanding perfusion applications where ultra low shear and safe processing ensure the highest yield.
Benefits

Highest Cell Viability

The most gentle pump technology

The magnetic levitation technology guarantees that no pump components come in contact with one another enabling a continuous and smooth flow. Additionally, the pump design ensures that no cells are trapped or damaged by tube compression, eliminating virtually all shear.

Automated Process Control

Easiest process control with the Levitronix® console

The Levitronix® console offers the option of easy and accurate control of retentate or permeate flow, pressure and even TMP.
Connect multiple flow sensors and pressure sensors to the console and let the system run at the desired process values, all with a single intuitive control unit.

Continuous Processing

No tubes or valves to wear out

Due to the constant gap between the impeller and the pump housing, no friction or wear occurs, resulting in a virtually unlimited lifetime.

Intrinsically Safe

No pressure build up or tube rupture

Set and limit the maximum pressure according to your tubing specifications and you will be assured that your media is safe no matter what occurs in your hydraulic flow path.
