Clara,
I am wust wondering about a few things re your problem:-
a) Is this just a single batch of tubes causing this problem?
b) What conditions are the tubes stored under? They haven't by any chance
been exposed to heat or something which may have changed the properties of
the gel?
c) How long are you giving them to clot?
d) Are the tubes getting the same "g minutes" as previously? (Changed a
centrifuge or something?)
Good luck solving this one.
Regards,
Ken

Subject: "solid" serum???
Dear colleagues
We have noticed lately that after centrifugation of our gel tubes (BD, SST1)
most of the serum phase becomes solid with very little liquid in its upper
part(no movement in the serum phase after inverting the
tubes)....................
