TFF-Easy – Tangential Flow Filtration-based Device

Overview

TFF-Easy is an advanced tangential flow filtration device designed for the concentration and desalting of sample solutions containing extracellular vesicles (EVs). This versatile tool is emerging as a new technique for EV isolation, especially when coupled with Size Exclusion Chromatography (SEC) columns.

Key Features

• Quantity: 5 concentrators per package

• Sample Type: Diluted EV-containing matrices (e.g., urine, conditioned cell media)

• Filter Cartridge: Polysulfone hollow fibers

• Sample Volume: Recommended 5-15 ml per reaction

• EV Recovery Rate: 83%

• Concentration Time: 5 minutes

• Reusability: Up to 20 times

Applications

• Concentration of diluted matrices (cell media, urine) prior to EV isolation

• Easy removal of small molecules and ions from EV preparations

• EV dialysis for changing buffer conditions

• High-efficiency EV isolation when coupled with SEC columns
