SpectrumLabs KrosFlo Tangential Flow Filtration (TFF) System with KR2i and KRJr Pumps, Tablet Control, and Bioprocess Scales
Product Description
The SpectrumLabs KrosFlo TFF System is a configurable tangential flow filtration solution optimized for bioprocessing and downstream purification workflows, widely used in molecular diagnostics and synthetic biology research.
Key technical features include:
- Dual peristaltic pumps: KR2i (115/230 VAC, 50/60 Hz, 2.2/1.1 A) and KRJr (24 VDC, 1.3 A) enabling robust flow control for membrane filtration.
- Integrated control: Tablet-mounted interface for intuitive system operation and real-time monitoring of filtration parameters.
- Communication module (KF COMM): Facilitates synchronization and remote control of filtration pumps and accessories.
- Precision weighing: Two Repligen KrosFlo scales with maximum capacities up to 60 kg, critical for accurate volume and mass measurements during ultrafiltration and diafiltration processes.
- Auxiliary pump modules: Additional pumps to expand filtration capacity and system versatility.
- Labeling supporting biotechnology workflows: 300 kDa cut-off membrane compatibility tailored for protein concentration and buffer exchange.
This TFF system is essential for applications in biomanufacturing pipelines, molecular cloning workflows, and cell therapy product purification. It supports continuous filtration processes required for large-scale protein separation, enabling reproducible and scalable results. The system’s modular design and precise electronic controls make it popular among biomedical engineers and biotechnologists seeking reliable tangential flow filtration solutions.
With compatibility for multiple voltage and power standards and incorporation of specialized biotechnology-grade pumps and scales, the KrosFlo TFF System is a valuable asset in clinical diagnostics labs and research institutions focusing on synthetic biology and bioseparation technologies.
