How Does It Work?

  1. Fill the upper integrated assembly with the powder of choice in a fume hood or biosafety cabinet.
  2. Zip-tie the bag from the top to close it and attach the assembly to the lift.
  3. Attach the lower integrated assembly to the vessel.
  4. Bring both assemblies together and zip the upper and lower zippers with the provided slider to lock them in.
  5. The upper and lower outlets for powder transfer can now be opened. Remove the Weloc or V-fold ties to open the channel between the upper and lower assemblies.
  6. Once the transfer is complete, the flaps can be closed, and the assemblies can be unzipped.
  7. The upper assembly can be discarded, and the lower assembly is ready for another transfer.
