What is Tangential Flow Filtration (TFF)?

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

Why choose a peristaltic pump for TFF?

Peristaltic pumps are often chosen for TFF due to their gentle pumping action, which is ideal for shear-sensitive biological materials, and their ability to handle a wide range of fluid viscosities without direct contact between the fluid and mechanical parts.

Can this pump handle different membrane types?

While the pump itself handles fluid transfer, KrosFlo systems are designed to integrate with various TFF membrane formats (e.g., hollow fibre, flat sheet cassettes) suitable for different applications. Buyers should confirm compatibility with their specific membrane requirements.

What maintenance is typically required for a KrosFlo peristaltic pump?

Due to their seal-less and valveless design, maintenance is generally low. Regular inspection and replacement of the pump tubing, which is the only wetted part, are the primary maintenance tasks.

Is this unit suitable for GMP environments?

While KrosFlo systems are widely used in research and development, suitability for specific GMP (Good Manufacturing Practice) environments depends on the exact model, documentation available, and the user's validation requirements. Buyers should verify with the seller.

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

Peristaltic pumps are valued in laboratory and pharmaceutical settings for their gentle, non-contact fluid handling, making them suitable for delicate samples and sterile applications. When buying used units, buyers typically prioritise checking tubing condition, motor functionality, and calibration history. Industry sentiment favours these pumps for their reliability, low maintenance requirements, and consistent flow rates. Common strengths include versatility across various fluid viscosities and compatibility with corrosive or shear-sensitive media. Prospective buyers should verify spare parts availability for specific models.
