Reduce Protein
Aggregation in

Tangential Flow Filtration (TFF) is a crucial step in biopharmaceutical manufacturing that requires the highest possible protein yield. Conventional pump systems such as peristaltic or 4-piston diaphragm pumps cause protein degradation due to mechanically induced shear of valves and tube compression. Furthermore, such systems generate a pulsating flow, resulting in non-optimal filter performance and reduced flux.

Levitronix® pump systems are designed for demanding TFF applications where ultra low shear as well as a pulsation free and continuously controlled flow ensure the highest protein yield.

Highest Protein Yield

No more protein aggregation

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 proteinis trapped or damaged by valve interaction or tube compression, eliminating virtually all shear.

Constant Transmembrane Pressure (TMP)

No flow fluctuations due to pressure pulsations

Levitronix® pump systems deliver a pulsation free flow, independent of actual flow or pressure. With optional pressure or flow sensors, the Levitronix® control unit will keep the pressure / TMP or flux constant, independent of fluid or filter properties.

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.

Cleanest Pump in and beyond Bioprocessing

Lowest particle shedding

TFF processes are generally at the end of the down stream process and any particle addition risks the purity of the final product. Due to the low shear factor plus no wear or mechanical contact between moving parts such as membranes or tubings, particle generation is eliminated. Levitronix® is the cleanest pump system and meets the purity demand of not only biopharma processes but also industries with much higher purity requirements such as semiconductor production.
