Z5 Serum Separator Tubes

[Tom Parish]

Hi netters,

I need help.  Has anyone used the Z5 serum separator tubes from LIP Limited?  
There are two versions available.   Does anyone know the advantages of using 
the bead vs gel product?

I am also trying to locate a number and address for LIP Limited.  It may be in 
the U.K.  If any of you Brits have heard of this company please let me know.

Thanks,

Tom Parish
