heliXcyto chips can be re-used many times. An automatic regeneration step is washing out your trapped cells after each measurement. Additional chip cleaning by an optional Chip wash is recommended. Extensive cleaning is also possible manually on the bench with our Chip cleaning kit. You only need to switch to a new heliXcyto chip if your background fluorescence exceeds the cut-off of 3 x 105 cps in the Cyto chip test and cannot be lowered by a manual chip cleaning anymore, or if the traps got lost.
