What is the primary function of an Akta Crossflow system?

The primary function is tangential flow filtration (TFF), used for concentrating, diafiltering (buffer exchange), and clarifying biological samples such as proteins, viruses, and plasmids.

Can this system be used for both ultrafiltration and microfiltration?

Yes, Akta Crossflow systems are typically versatile and can accommodate both ultrafiltration and microfiltration membranes, depending on the specific cassette installed.

Is this unit suitable for GMP environments?

Many Akta Crossflow systems are designed with features like CIP capabilities and robust control, making them suitable for use in regulated GMP environments. Buyers should verify specific unit documentation.

What types of samples can be processed?

This equipment is commonly used for processing a wide range of biological samples, including proteins, antibodies, viral vectors, plasmid DNA, and cell cultures.

Are consumables, such as filtration cassettes, readily available?

Filtration cassettes and other consumables for Akta Crossflow systems are widely available from Cytiva and third-party suppliers, ensuring ongoing operational support.

An ÄKTA Crossflow filtration system is a type of tangential flow filtration (TFF) system developed by Cytiva (formerly GE Healthcare). It's used primarily in bioprocessing and biotechnology applications to concentrate, diafilter, or clarify biological samples such as proteins, viruses, plasmids, and other biomolecule

Core Functions:

Concentration – Reducing the volume of a sample while retaining the target biomolecule.

Diafiltration (Buffer Exchange) – Removing salts or changing the buffer environment by continuously adding a new buffer while removing permeate.

Clarification – Removing particulates or cells from process fluids

Key Components:

Pump Modules: Typically peristaltic pumps that manage flow rates precisely.

Filtration Cassettes: Hollow fiber or flat sheet membranes for ultrafiltration or microfiltration.

Pressure Sensors: To monitor and control transmembrane pressure (TMP).

Conductivity/pH/UV Detectors: For in-line monitoring of the filtrate and retentate.

Benefits:

Automation reduces operator error and variability.

Scalable design for seamless transition from lab to production.

Precise control of filtration parameters (flow rate, pressure, volume).

CIP (Clean-In-Place) capabilities for easy maintenance and compliance with GMP.

Common Applications:

Protein concentration and buffer exchange

Viral vector purification

Plasmid DNA purification

Cell harvest and clarification
