We have a Helmer EBA centrifuge in our lab for routine blood bank testing.  We have a 12-tube rotor with these tube holder inserts to hold our 12 x 75 tubes.  The inserts are plastic and several have broken due to normal wear and tear.  We recently ordered some new inserts and before we start just replacing the old with the new, I'm wondering if there needs to be some sort of validation performed?  Seems pretty petty, but I've seen other situations where a validation isn't obvious, but was required.

Thanks for any assistance!

I think the manual we have asks us to replace them on a regular basis (every 2yrs? I don't have it in front of me), we do not validate (or re-validate) after replacing

This is a like-for-like replacement using OEM parts, and supposedly, as suggested by the manufacturer (see jmm8427's post above). My opinion: No validation of any kind required.

Original validation of serological centrifuge is done to determine the correct RPM (or CF) and time for obtaining the optimal cell button. Unless you do something to the centrifuge that affects one of these two factors then re-validation is not required.

Thanks everyone!
