Brief Intro of Small Tangential Flow Ultrafiltration System
Time：2018.03.16
Understand Tangential Flow Ultrafiltration Technology
Tangential flow filtration (TFF), also known as cross-flow filtration (CFF), refers to the form of filtration in which the liquid flow direction is perpendicular to the filtration direction. The liquid flow generates a shear force on the surface of the filter medium, which reduces the accumulation of the cake layer or the gel layer, thereby ensuring a stable filtration speed.
According to the size of the trapped particles or molecules, it can be divided into microfiltration MF, ultrafiltration UF, nanofiltration NF and reverse osmosis RO.
TFF technology is widely used in pharmaceutical, biological, chemical, food and beverage and environmental protection industries, etc.
Brief Introduction about Small Tangential Flow Ultrafiltration System
System overview:
The small tangential flow ultrafiltration system is a TFF device designed and developed by Beijing Holves for laboratory users. It is mainly suitable for small-scale or pilot-scale TFF research in the laboratory. The system adopts imported original box flat film packs, which can realize microfiltration and ultrafiltration to meet the diverse needs of the laboratory.
