Hey all, hoping to get some real-world takes from folks who've actually used the shorter 40mm capillary tubes on a StatSpin microhematocrit centrifuge. We're kicking around the idea of switching from the standard 70-75mm and I'd rather hear it from people running them daily than from a vendor spec sheet.
A few things I'm curious about:
Are you getting a clean packed cell column at the normal 2 minute spin, or did you have to mess with the time? Any plasma trapping weirdness or fuzzy interface on the shorter column?
Does the shorter column hurt precision when reading? Or is it kind of a wash because there's less tube to fight with on the reader card? Curious if tech-to-tech variability got better or worse.
Easier or harder to teach? Wondering about fill consistency, seal quality, breakage, all the usual newbie pitfalls. Did you see fewer redraws, more, or about the same?
Worth it overall? Did you stick with 40mm or end up rolling back to 75mm?
For context, we're a Core Lab and mostly use spun hct for QC checks and the occasional manual on a flagged sample, so not crazy volume. Mixed experience staff, some seasoned and some newer.
Appreciate any input, even short "we tried it and hated it" replies are useful.
