Our lab just purchased 3 Helmer EBA 21 centrifuges, with swing-out style rotor for 12 x 75 tubes rather than fixed angle. We currently use some aging Serofuges - - we are used to seeing our cell button toward the side of the tube. The new fangled ones have the button lower in the tube, almost on the bottom. Is this an issue, or just something we need to adjust to??

Thanks for any input!

In my many years of blood banking, I've never used a full swinging rotor for serological testing, but there is no reason that you can't. I'd have to calibrate it and reteach my techs how to properly read buttons that aren't on the side ...

I think this is larry's last post. We will miss you larry.....
