Drum to Bag/Bottle Transfer with Open Containment

The Rheo Material Transfer Station is a small footprint workstation that improves operator safety and efficiency during the material transfer and weighing process. The operator workstation with the integrated drum tipper provides a compact, GMP, ergonomic means of transferring material.

The Material Transfer Station with Open Containment is designed for simple open transfers. Containment levels of 100-10 µg/m3 can be achieved via the integrated Rheo Ventilation Sleeve.

Rheo has conducted containment verification tests on the Material Transfer Station. The tests showed excellent results for each of the different configurations tested. Copies of the executive summary, full reports, and supplemental documentation are available upon request.

The Drum to Bag/Bottle configuration is used to transfer materials from drums into bags or bottles in order to repackage the material into a more GMP or usable container or to pre-weigh a material kit using the integrated scale. The newly packaged bags/bottles can then be transported to a manufacturing space for batch processing.


The Material Transfer Station with Open Transfer Containment has several benefits when implemented in the manufacturing process:

  • Ergonomic Product Transfer
  • Quick Deployment
  • Limited Cleaning Time
  • Modular Design
  • Easy Access to Product
  • Portable Dispensing Suite
  • Containment (100-10 µg/m3)
  • Small Footprint

Fold-Down Table:

Drum to Bag/Bottle Transfer Module for the Rheo Material Transfer Station

Open Transfer System

The Drum to Bag/Bottle Transfer Module is designed to hold the receiving container so product can easily be transferred. For Open Transfer Containment, a bag or bottle can be clamped to the bottom of the transfer module while the integrated Rheo Ventilation Sleeve provides containment across the top of the transfer module opening. Using this process to provide containment is designed to keep operator particle exposure to 100-10 µg/m3. The containment module can rotate up to help with the clamping and unclamping of a bag. 

Dust Extraction

The integrated Rheo Ventilation Sleeve provides localized dust extraction to contain airborne dust and vapor. The full perimeter slot design provides 360 degrees of extraction to ensure that proper air velocity is maintained in the dust zone despite obstructions, such as an operator’s hands or a drum liner.

Rheo has conducted containment performance verification tests on the Material Transfer Station. The tests showed excellent results for each of the different configurations tested. Copies of the executive summary, full reports, and supplemental documentation are available upon request.

Material Transfer Station - common applications for Rheo equipment

Common Applications

  • Weigh and Dispense
  • Repackaging
  • Sampling
  • Charge Pot Filling

Integrated Weighing

The integrated weighing system provides a compact solution for the weighing and dispensing operation. The weighing module that holds the receiving container is isolated from the workstation to provide excellent weighing accuracy.

The typical integrated weighing system includes the following features:

  •     150 kg Weighing Capacity
  •     Mettler Toledo IND570 or IND560X Readout
  •     4x Mettler Toledo Load Cells
  •     Weigh Accuracy to +/- 50 grams (higher accuracy, low capacity options are available)
  •     Can be Integrated with Computer, PLC, or Printer

Integrated drum tipper from Rheo

Drum Tipper

The integrated pneumatic Drum Tipper can be used to lift a wide variety of incoming containers and slide it towards the operator for easy dispensing into the receiving container. Pneumatic controls provide safe, controlled operation of the Material Transfer Station.

  • 150 kg Drum Capacity
  • Pneumatic Drive System (90 psig, 8 scfm Clean, Compressed Air)
  • Material of Construction: 304 Stainless Steel Frame Structure, 316 Stainless Steel Drum Cradle and Product Contact Surfaces

Modular Design

To increase the utility of this equipment, Rheo has developed a quick and easy change over from an open transfer system (that uses a dust extraction device to capture fugitive dust) to a high-containment system that uses a flexible Restricted Access Barrier System (RABS). This modular design offers two levels of containment controls to accommodate the full span of compounds.

Transfer Modules are also designed to be quickly replaced in order to change between different types of receiving containers (example: change from a Drum to Drum Transfer Module to a Drum to Bag/Bottle Transfer Module).

Clean the entire Material Transfer Station


All exposed surfaces on the Material Transfer Station can be fully washed-down for cleaning. Some configurations of the Material Transfer Station include WIP spray-ball systems to wash the product contact surfaces. 

Operator Centric Design

By designing around an analysis of operator movements during the drum charging process, an unmatched level of safety, operating simplicity, and functionality is achieved. A drum can be raised, lowered, and tipped into the proper position by using a single hand or foot control. This approach to drum handling allows the operator to easily control the product flow during the entire charging process.  

Material Transfer Station by Rheo is engineered with operator centric design.

Testing Center

Powder handling can be a challenging process and there are many factors that lead to the optimal solution. We can handle the risk for you! Our Testing Center is equipped to test your materials, allowing us to design the best solution for your specific needs. We don’t just sell a product – we sell a solution.

We can utilize the Testing Center for process testing, powder flow testing, transfer rate testing, concentration testing, and containment performance verification.
