Imagine one technology adaptable to so many process steps. Swapping out a fluid handling unit and process specific single-use cartridges makes it possible.
Whether you need to process an apheresis product or are harvesting from a bioreactor, the ekko system processes continuously without interruption. Flexible control allows for a wide range of inputs & final concentrations, yields or processing times. Peace of mind knowing that cell viability is maintained due to the low energy acoustic mechanism. Cell lines we have processed include:

Notes:
Comparison of T cell population phenotypes before and after ekko™ cell processing. Phenotypes determined using flow cytometry show no impact of processing:
The ekko™ system can be connected to your bioreactor of choice to enable a closed, integrated, and automated solution for your PSC aggregate expansion or differentiation process. The system is tunable to maximize single cell removal or aggregate retention at each step while being gentle by minimizing time out of your reactor. Multiple unit operations can be performed such as:
