Hi
We also were experiencing the same situation. We use to use the Thermo 
Shandon cysto spin chamber but we found that some of the material would 
still be in the funnel. So... actually by mistake one day I noticed that 
their 2 reagents sent with the pack, one is a formalin fixative and the 
other is a Calcium Chloride; form a nice clot.
Now we just add 4 drops of the Blue reagent to the cell button and 
resuspend. Then add at least 5 drops of the Clear reagent to form a great 
clot. Then pull it out and wrap it in tissue paper.We have really increased 
the retrieval of cells
Hope this helps
