[RASMB] Epon centerpiece

[Chen Mengdi]

Dear all,

I ordered an AUC cell assembly from Beckman which contained an Epon centerpiece. But only after a few runs, the cell was leaking even without vacuum. I found that the centerpiece cannot be pushed smoothly to the bottom of the cell when I assembled the cell.

Has anyone of you met this similar problem? Any there any suggestions for solving this problem? Shall I use an O ring on top of the centerpiece to seal the cell, like how we assemble the Al centerpiece?

Many thanks.

Best wishes,
Mengdi Chen
