Was originally designed as a replacement for expensive wave bag system from GE and Sartorius. Fully avoiding patent infringement's by introduction of engineering vision. We decided 2016 that CellTumbler will continue, but as a low priority product. CerCell support happily the existing installations as well as new installations.
The first CellTumbler's was manufactured in 2010. All the units built between 2010 - 2012 are still in daily use 2020. Illustrating minimum maintenance is needed. Only wear part turned out to the the little nylon roller on the crank wheel. This means lifetime is easily 50.000 hours.
