Instrument specifications
Easily fitting on a benchtop, the compact CTS Rotea system’s counterflow centrifugation technology was designed to gently and efficiently separate cells or aggregates based on size, and to concentrate particles with outer diameter (OD) >5 μm.
The proprietary Gibco DirectDraw extraction technology allows users to gently and precisely recover washed and concentrated cells from the processing chamber at the extremely low-volume output of 5 mL and is ideal when electroporation is the next step. In addition, the CTS Rotea system incorporates multiple sensors to monitor and protect the integrity of the closed system.
