Following up on this: if the problem is with the yellow stripe, one can
replace the reflective sticker without replacing the whole spinner. Part
number for the replacement stickers is Z42852.

Side note: that particular shade of yellow can be an issue in itself. We’ve
noticed the detection optics of our SampleCases being triggered in weird ways
when samples have yellow components at their top. E.g. yellow-topped J-Young
tubes (short) and yellow-colored sample solutions (consider a bulb-topped tube
that got pretty full in the course of a titration).

I don't have any answers, but I can add to the confusion. It seems that the
shape of the blue POM 5-mm spinners has changed over the years. On our
SampleCase, the older style spinners that are straight at the bottom and have
a thicker yellow stripe fail much more frequently than the newer ones with
the indent at the bottom and thinner yellow stripe.
