Frequently Asked Questions


The ProConnex® MixOne Carboy System is modular with an extensive component library of different sizes, tubes, fittings, etc. The one showed in the video is 40L. Please consult your sales rep for your particular needs.


Stirbars are typical lab mixers that have limited capacity and performance when it comes to mixing at production scale. The ProConnex® MixOne Carboy System mixer platform is designed to meet and exceed the pharma needs at a production scale, with unparalleled mixing performance in combination with the TrueLev bearingless technology that eliminates any particulate shedding that is related to stir bars.


The container with a window is perfect for visual evaluation of your mixing performance. It is not a standard product, but it is available upon request. A typical application would be in your R&D evaluation step as a bridge before moving to product models without window. The window model does not come as irradiation compatible and because of that in most cases not suitable for production.


The ProConnex® MixOne Carboy System is easily operated by docking the container to the drive unit platform. The mixing system can be controlled in two ways:

Digital through either a handheld control panel or through your existing external control system

Control of the ProConnex MixOne System can be performed digitally, through either a handheld control panel or your existing external control system.

Through PLC

Control of the ProConnex MixOne System can alternatively be controlled through at PLC.

The ProConnex® MixOne Carboy System container in the video is made for low shear mixing of media that requires a sterile and aseptic environment. After filling through the filling line it can remain in its closed system for storage. When the product is to be used, the ProConnex® MixOne Carboy System container is simply reinstalled on the platform and the mixer turned on to resuspend the product. To check the quality of the product and the mixture the system is equipped with four aseptic samples lines made of C-flex tubing that can be welded on a sampling container. To facilitate ease of use during operation and installation, it is equipped with tube holders locating, protecting, and preventing tangling of the tubes during handling. The vent line has a pressure sensor to leak test the unit before use. The container has a low point drain line for easy emptying with an aseptic quick connect at the end of the line.
