What is the primary advantage of a peristaltic pump for TFF applications?

Peristaltic pumps offer gentle, low-shear pumping, which is crucial for maintaining the integrity of sensitive biological materials during tangential flow filtration. Their seal-less design also prevents contamination.

Can this pump handle viscous fluids?

Yes, peristaltic pumps are generally effective at handling a wide range of fluid viscosities, making them suitable for various laboratory and bioprocessing applications.

What kind of tubing does this pump typically use?

Units of this type commonly use various types of peristaltic pump tubing, selected based on chemical compatibility, pressure requirements, and desired lifespan for the specific application.

Is this unit suitable for continuous operation?

Peristaltic pumps like the KrosFlo are designed for both batch and continuous operation, depending on the specific application and the lifespan of the tubing used.

What is Tangential Flow Filtration (TFF)?

TFF is a filtration method where the fluid flows tangentially across the surface of the membrane, rather than perpendicularly through it. This minimises membrane fouling and allows for continuous processing.
