If you had snapped a capillary, it would then be dealt with by
very small flow rates just to push out its contents, so no whipping around an edge with
bernoulli pressure drops.

I get that score-snapped

Yes, they could be pushed against a port for putting pressure on them to empty them.

A robot hand could move them around, and a robot eye could check how far gel or liquid is pushed out,
then stop, the toss the capillary section in trash, flush and clean that rubber sealed air pushing port
occasionally...
