Advanced Support Hardware for Single-use Systems
Pall Allegro jacketed totes have been specifically designed and engineered to provide state-of-the-art performance of single-use systems in thermal control applications. The jacketed totes are part of the Allegro platform from Pall Life Sciences; a comprehensive program providing process solutions, technical support and validation for single-use systems. Fully integrated multicomponent and multi-technology systems are provided as validated solutions for fluid handling.
The Allegro jacketed totes are designed for temperature control or thermal regulation applications for process fluids where fluid containment and safety in operation are paramount. Superior performance is achieved through innovative and complimentary designs of both the totes and the systems designed to fit in them. Full access into the totes, ease of installation of single-use systems and self filling with minimal operator intervention are just some of the key features. Please refer to additional Pall literature (ref USD 2519) for more details.
- Dimensionally identical to standard Allegro 3D totes
- Sanitary nozzle connections for inlet, outlet and low point drain for heating/cooling fluids
- Allegro wheeled trolleys from Pall enhance mobility
- Can be stacked in combination with existing totes to maximize floor space (Note: not to be stacked when using a trolley)
- Stainless steel surface is passivated providing enhanced corrosion resistance
- Jacketed on 4 sides, including the bottom, to maximize thermal transfer
- Insulated with NH/Armaflex® thermochannels on all jacketed faces for heat conservation and personal protection
- Excellent internal surface finish (Ra < 0.5 μm) maximizing contact for efficient thermal transfer.
Tote Inlet, Outlet and Drain Connections
The Allegro jacketed totes provide very efficient heat transfer via specially designed thermo channels incorporated in the design.
The thermo channel design forces the cooling/heating medium into a state of turbulence in a controlled and even distribution over the complete heat transfer area – especially
at low flow rates, maximizing heat transfer coefficient.

The Allegro jacketed totes can be used for general thermal control applications such as:
- Media & buffer storage, heating or cooling
- Suspension and temperature equilibration for slurry solutions (e.g. vaccine adjuvants)
- Product fraction collection with temperature equilibration
- Product/buffer/media homogenization with temperature equilibration
