minus-squareassassinatedbyCIA@lemmy.worldlinkfedilinkarrow-up9·5 days agoI wonder what gauge needle that is?
minus-squareInsolentjellyfish@lemmy.worldlinkfedilinkarrow-up23·5 days agoAt very rough estimate, I would guess a 30 gauge needle. They have an outer diameter of .31 mm. A blood cell is about 7 micrometer across. It looks like you can fit more a smidge fewer than 50 cells across the thickest part of this needle. Cheers!
