Mixers and Mixing Systems

A number of companies offer commercially available, well-engineered single-use mixing systems, for examples, Pall, Millipore, Thermo Scientific, Sartorius, GE Healthcare, etc. They are available with different bag sizes, and ideal for applications such as buffer and media preparations, viral inactivation post-harvest, and final conditioning in the formulation step. However, mixing with single-use system bring its own processing challenges, for example, solutions in soft-walled bags do not always behave according to typical fluid dynamics as they would in rigid, cylindrical vessels. Also, sometime it is difficult to find good mixing systems that are scalable, partially because each mixing system has its own specific bag film and construction, alsonot all products offer small-scale applications.

Saint-Gobain Recirculating Mixing System 

Single-Use Bioprocess Recirculating Mixing System has been developed to create a simple and effective single-use mixing alternative for biopharmaceutical applications. The mixer design utilizes an externally mounted pump to recirculate and mix the fluid in a single-use bag system. The pump on the mixing system has no bearings to wear out or seals to break. Utilizing magnetic levitation, the pump’s impeller is levitated inside a sealed casing and driven by the magnetic field of the motor, therefore eliminate particle generation.

Sartorius Single-Use Mixer Platform

Sartorius Flexel® Single-Use Mixer products include  Flexel® for LevMixer® and Flexel® for Magnetic Mixer.  Flexel® for LevMixer® has a levitating impeller for Ultra Clean Mixing (no friction), low-shear mixing for sensitive product, liquid-liquid mixing, homogeneization and re-suspension. Flexel® for Magnetic Mixer® has strong magnetic coupling for: powerful mixing with high-torque and high rotation speed, high viscosity and/or concentrated powders dissolution, and large volume. More information on these technologies in the linked Brochure.

See Metanova Zero-g magnetic mixer technology brochure.

Parker Bioprocess Mixing Systems

Parker provides bioprocess mixing systems including the PoGo G2 and SpinBag™ systems: PoGo G2 is a single-use mixing system for media and buffer preparation. It uses a fully programmable reciprocating motion that combines efficient mixing with low shear effect.  The system consists of a freestanding mixing base and detachable mixing tank for quick change overs. The PoGo G2 can be used with Parker’s DuraPure single-use bioprocess mixing chamber or as an open top mixer. Stroke and speed are controlled by a programmable HMI touch screen or by a manual control panel option.  SpinBag™ bioprocess container is a compact table top mixing system, each 3D SpinBag is constructed of DuraPure film with a specialty coated magnetic stir bar inside. When placed on the mixing plate, the bar rotates to create a vortex of motion to thoroughly mix or stir the fluid contents. The versatile mixing plate drive unit also has a small footprint and is compatible with SpinBags in a variety of volumes and port configurations. In addition, the easy-to-operate, programmable control panel allows users to adjust parameters such as the speed and temperature.
