Allegro™ 2D Powder Port Biocontainer – Recirculation Mixing At 20 And 50 LSource: Pall Life Sciences - BioPharmaceuticals
Mixing systems are often used to prepare buffer and media solutions while controlling important fluid parameters such as pH and conductivity. Such systems can vary for a wide range of applications and volume sizes. Pall Life Sciences has introduced a user-friendly, single-use mixing system for small volume batches. This system, as shown in Figure 1, is comprised of an Allegro 2D biocontainer that contains a powder port intended for solids introduction and associated tubing. Added liquids and solids are mixed using a peristaltic pump to transfer the fluid from the outlet port of the biocontainer to the inlet port through a recirculation loop. The peristaltic pump creates a jet stream from the recirculation loop into the biocontainer resulting in turbulent mixing. The Allegro biocontainer mixing systems are available in 20 L and 50 L sizes each containing ½ in. inlet and outlet fittings, with targeted application volumes from 10 to 50 liters.
