The FLEXMIXER20EH is an electrically actuated mixing device with temperature control for use with the FLEXBAG20L-S and FLEXBAG20L-NS disposable mixer. Fluids to be mixed are placed in the FlexBag¨ and attached to the FlexMixer¨ actuator. The actuator moves the septum up and down rapidly to provide complete mixing in seconds. The single-use mixing system eliminates costly cleaning and validation while maintaining product purity. The electrically driven unit is portable, and has an integral easy-to-clean spill containment pan.
