Challenge Dream+ Tangential Flow Filtration(TFF) System

Challenge Dream+ fully automated tangential flow filtration system is a fully automated, digitalized, and intelligent system, which is developed based on tangential flow filtration (TFF) technology. The system integrates a feed addition unit, weighing unit, magnetic stirring, pressure sensors, pH/conductivity, and flowmeter. It can automatically record over 20 process parameters, including TMP (transmembrane pressure) and FLUX (permeate flux), and is capable of automatic TMP control and automatic flow path switching.The entire filtration process (including pre-filtration treatment, equilibration, sample loading, concentration/diafiltration, sample collection, and post-filtration treatment) can be automated with one-click operation after method editing. It is a fully automated tangential flow filtration (TFF) system capable of "unattended" operation.It enables intelligent TMP optimization, effectively supporting the development, optimization, and scale-up of TFF processes.
01

Features

01

Simultaneously used for development and production, flexible and versatile

The system offers stable and reliable solutions for all stages, from lab-scale to pilot-scale and commercial production.

02

Convenient for linear conversion of process parameters

As a GMP-compliant system, it provides a dependable development environment with consistent process parameters, establishing a strong foundation for seamless production scale-up.

03

Smart operating system, easy to use and efficient

With a plug-and-play hardware design, the system easily transitions between various application scenarios (UF/DF/MF) and operational states (R&D/production). This design enhances efficiency and flexibility while minimizing fixed asset investment.

04

Digitization of data recording

The user-friendly Challenge Navigator software features an intuitive interface and an electronic signature system compliant with 21 CFR Part 11. It ensures process stability and repeatability while its GMP-based automation and program architecture simplify scaling processes, offering unparalleled convenience for both upscaling and downscaling.
