Major Science Winpact Fermentation System:

Benefits of system:

Intuitive layout

Learning to work a fermentation system has never been easier with the Winpact touch screen controller. It combines sophisticated functionality with intuitive software layout, which allows for  anyone from a highly trained fermentation specialist to a first year undergrad to run complex batches with ease.

15 step programmable automation:

The winpact controller system allows you to automate your process more than any other benchtop system. With the ability to program up to 15 different steps with a maximum of 99 minutes per step, the longest and most complicated methods can be programmed with ease and run without monitoring.

Agit Program


Peristaltic Pump Calibration

Need to know exactly how much feed or acid you are adding to your batch? The Winpact fermentation system is the only benchtop system that allows you to do just that. Following a simple procedure, it allows you to calibrate your peristaltic pumps so that you know exactly how many mL per minute you are adding to your vessel.

Pump Setting


Continuous Chart Recording:

One of the key reasons for using a fermenter over growing cultures in a flask is the ability to monitor your parameters. Winpact controllers allow you to continually monitor your temperature, pH, DO, Agitation and more throughout your entire run. All of this data is easily exportable with a USB drive or can be stored directly on your server with a network connection to the controller box.

Remote Troubleshooting

Not all problems require a technician to come on site, especially when you have a highly skilled technical staff that is available for phone support. When you buy a winpact fermentation system through GMI, we can help resolve these issues while avoiding expensive service visits. The system allows you to capture pictures of the system log using a USB drive, these system logs can then be sent to our fermenter technician who can help offer remote solutions before coming on site. If the issue does require some on site support, the ability to give the engineer the system data log means we can come better prepared to solve the problem, including pre ordering parts to bring the first time, which could eliminate the need for multiple visits, which again can save money in your service budget.
