The Levitronix® PuraLev® iF100 Single-Use flow controller is designed for for demanding fluid applications in bioprocessing where extremely low shear, pulsation-free, and continuously controlled flow ensure the highest product yield. Based on the principle of magnetic levitation, the pump impeller is suspended, contact-free, inside a sealed casing and is driven by the magnetic field of the motor resulting in a continuous smooth flow. The motor and pump controller, as well as the flow converter, are integrated into the driver housing resulting in a significantly reduced footprint. The pump head is made of gamma stable polypropylene that meets the highest biocompatibility requirements such as FDA, USP-VI, and BSE/TSE free. The pump head is disposable and can be exchanged in few seconds.
Proven by industry experience – The most gentle pump technology within bioprocessing!
The magnetic levitation of the pump impeller enables a contact-free operation and a low shear design for gentle pumping of sensitive liquids like cells, proteins, and LNP’s.
Maintain your liquid purity
The low shear factor and the lack of wear or mechanical contact between moving parts eliminate particle generation and maintain the purity of your liquid.
No more tube ruptures
Set and limit the maximum pressure according to your tubing specifications, and rest assured your media is safe no matter what occurs in your hydraulic flow path.
FDA, USP-VI and BSE/TSE free and Gamma Robust
All wet materials are fabricated from biocompatible (FDA, USP-VI, and BSE/TSE free) gamma stable (up to 40 kGy) polypropylene (PP).
Accurate, stable, and reliable flow and pressure for your process
The open pump head design, high flow resolution, centrifugal pump principle, and the absence of valves lead to a completely pulsation-free flow.
Up to 17 lpm / 4.5 gpm
In comparison to positive displacement pumps, there is a continuous discharge of liquid resulting in high flow capabilities.
From a few mlpm up to max flow
PuraLev® pumps can accurately control and maintain a smooth flow from just a few mlpm up to the maximum flow rate, giving them the highest turndown ratio among competitive pumps.
Significantly smaller footprint than positive displacement pumps
All PuraLev® pumps have a much smaller footprint than competitive pumps of comparable hydraulic performance. The magnetic bearing also eliminates any noise generation from your process.
No tubes to wear out or diaphragms to break
The magnetic levitation principle guarantees that no components come in contact with one another, allowing for robust and safe processing.
No particle agglomeration
PuraLev® pumps have the unique capability to deliver solid-liquid mixtures without particle agglomeration or pump wear out.
