Is there still a good serological centrifuge out there?

Recommended Posts

We have been trying to buy a new serological centrifuge but the Clay Adams is backordered for months.  All of the vendors keep suggesting others that they think will work.  We have already tried a Hettich EBA21 and just can't get it to work as well as the old Clay Adams.  We get different results on titers using the 2 different centrifuges. Cell suspensions that are washed in it end up mixed once the braking stops.  If we set the brake lower, it takes too long to stop.  Is there a good serofuge for sale in the US anymore?  I miss the Immufuges of 1985.   :(

We have a Hettich EBA-21 that seems to work OK.  But we mostly use our Clay Adams sero-fuge 2001s .  Not sure they still make the EBA-21s.

Yeah, but once you had your fingers broken, you are back to not having a brake!

Ah...but you have to carefully calibrate the use of that finger or fingers. And bare fingers worked better than gloved fingers. Of course, that was before we really had gloves.

It was so hard when teaching students not to reach over and flip open that lid. Remember changing broken clips on the immufuges?  Or the Dade Cell Washer that added the antiglobulin?  I think that is why manufacturers started makng green antiglobulin.

I used to use a 10mL tigertop tube, it was an excellent brake! :D

We just tried to order Serofuges for our student lab, and found out that BD no longer makes the Serofuge.  Does anyone know when they stopped?  What are people doing?  I think we found some sources for the Serofuge 2002--but when those sources dry up, I think we'll have to go to another manufacturer for our student labs.

We use the Hettich and have separate programs set up so only the wash program has the longer break time included. We also have a site that set two wash programs (one for larger cell suspensions and one for cell button only) allowing only one program to be affected by the increased break time.

That's how ours are set up.

At our facility I'm in the process of switching out our Hettich EBA-21 with the Hettich EBA-280.  In our validation there was no major differences between the two.

There is a new company that I saw at the AABB meeting.  Their centrifuge takes the Serofuge heads and otherwise looked promising.  They will let you try it for free.  Drucker Diagnostics' SERO 12  Has anyone tried it?
