TANGENTIAL FLOW FILTRATION

BRIEF INTRODUCTION

AITESEN LDS series Tangential Flow Filtration is mainly applied in the research of tangential flow ultrafiltration technology for micro & nano drugs and biological products, providing excellent technical services and solutions.

The equipment can be used for process research experiments on small-scale samples, as well as for large-scale process validation experiments. The equipment is equipped with a touch screen operating system and software programs for automatic data recording, supporting data tracing and export. The process is reliable and suitable for programmatic amplification. The components comply with pharmaceutical industry standards, they are safe and reliable.

TFF:

Tangential Flow Filtration (TFF) is currently a widely used membrane separation technology. The sample is driven by pressure, and the content is separated by membrane filtration according to different molecular sizes, achieving the goals of removing heat, replacing the solution environment, purification ,and concentration.

PRINCIPLE：

The implementation process of TFF is fundamentally different from dead end filtration. As the filtrate passes through the membrane components, the sample solution continuously passes through the membrane surface in a vertical direction.

MEMBRANE PARTS：

The membrane components for tangential flow filtration are usually membrane packages or hollow fiber columns, both of which have multiple models to meet different usage needs. The type and pore size of membrane materials, solution circulation flow rate, pressure on both sides of membrane, sample temperature, process on both sides of the membrane, sample temperature, process time and other parameters are very important for tangential flow filtration. They determine the final process effect, as well as the feasibility and specific plan for large-scale production. The laboratory scale tangential flow filtration equipment is committed obtaining feasible process plans and reliable process parameters, determining suitable process parameters for large-scale experiments and production, and providing effective basis for equipment or system selection.
