We are renovating and need to sell two Chemap bioreactors and the control unit . They are 10 L and 100 L working volume vessels. The larger one is still attaching to its piping and it is working great because we took good maintenance care. The smaller one still works but may need fixed once awhile. The system come with their control unit which is Braun DCU 1 and works great. The DCU can be excellent for spare parts if needed. May include some of the electronic items that have been bought for spare items and the system accessories. These are large and heavy items. Local pick up only. We are located in Campbell, CA.
