Holding onto the interdental brush, use a clean cotton bud to push the flowcell
up out of the measurement block from below. As the flowcell exits the block,
angle the brush so the flowcell does not fall off.
5.
Place the flowcell onto a clean lint free cloth.
6.
If sample build up is suspected inside the flowcell a wetted interdental brush
can be used to gently clean the internal channel. Take great care when per-
forming this operation as the central core of the brush is metal and could
potentially damage the flowcell.
7.
Remove any sample or grease by
lightly
dragging a clean lint free cloth over
the flowcell; if desired the cloth can wetted with ethanol or propan-2-ol.
Repeat this action for each optical side of the cell.
