In the biopharmaceutical industry, researchers face challenges not only in the complexity of experiments, but also in how to process experimental data efficiently and accurately. To this end, Cobetter follows the core needs of biopharmaceutical developers and launches the easy-to-operate and comprehensive Biophsep™ TFF System - MiniLab experimental-grade ultrafiltration system.

This "R&D Helper" not only optimizes the experimental process, but also makes the operation easier and faster through its humanized design, greatly improving R&D efficiency. It can help researchers easily cope with various challenges in experiments and is suitable for process research or process characterization at different stages. From clarification to concentration to liquid exchange, every step is precise and efficient, ensuring the accuracy and reliability of experimental results.

Components and Accessories

Biophsep™ TFF System - MiniLab experimental grade ultrafiltration system consists of peristaltic pump, proportional pinch valve, balance, control cabinet, tablet computer and data processing software.

Users can freely select and configure according to their needs, and independently develop data processing software set settings. Plan, collect data by yourself and form reports, one-click operation and other functions are integrated into one. High degree of automation, flexible and convenient to use.
