Rheo Flexibles provides a wide range of single use transfer containers. The RheoPac family of products offer an excellent alternative to stainless intermediate transfer containers. The RheoPac can be designed with many valve and bag design configurations.


The RheoPac can be equipped with an integrated SoliValve® passive that will allow the RheoPac to dock to Visval SoliValve® dosing technology. This SoliValve® technology uses a split cone valve to provide automatic docking and high containment during powder transfer from the RheoPac to the receiving container.


MTS Dispensing Workstation

Rheo offers a GMP dispensing workstation for filling RheoPacs. This system has a built-in Drum Tipper as well as an integrated load cell system that allows for weighing directly into the RheoPac.

Transport Cart

Rheo can provide GMP transfer carts to provide an easy means to transfer the filled bags from the dispensing station to the transfer point downstream in the process.

Column Lift

Rheo can provide a GMP column lift that can be used to lift and position one or multiple RheoPacs into position above the receiving vessel.


Many accessories can be provided with our RheoPacs to create a complete high containment system, some of these accessories include:

  • Weloc Clamps
  • Tri-Lock Clamps
  • Gaskets
