The fold-out frame supports a Flexible Isolator that allows a variety of dispensing procedures. On one side, an air-tight zippered door can be used to introduce materials and tools into the isolator before a dispensing operation. A drum can be docked to the back of the isolator using a drum sleeve for high containment and the drum access is ergonomically accessible for the operator. Below is a sanitary flange outlet with a tri-clamp connection for enclosed filling of RheoPacs. At the side is a permanently-welded disposal port for emptied bags and other waste items. With the drum dispensing port, a drum can be placed under the isolator for filling.
