LDS-L1 TANGENTIAL FLOW FILTRATION/Solvent removal/TFF ultrafiltration

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：

用于切向流过滤的膜组件通常是膜组件或中空纤维柱，两者都有多种型号，以满足不同的使用需求。膜材料的种类和孔径、溶液循环流速、膜两侧压力、样品温度、膜两侧工艺、样品温度、工艺时间等参数对于切向流过滤非常重要。他们决定了最终的工艺效果，以及大规模生产的可行性和具体计划。实验室规模的切向流过滤设备致力于获得可行的工艺方案和可靠的工艺参数，确定适合大规模实验和生产的工艺参数，为设备或系统选型提供有效依据。
