Thank you, Prakash for the information.  GE Healthcare (Whatman) has discontinued DED81 filter paper/discs, and do not have a replacement for this product.  I am having GE Healthcare make one final batch of DE81 filter paper with the supply of raw material they have left after this they will not make the item available to anyone.

Hi Matthew,

Were you able to find any alternate source for the DE81 paper by GE Healthcare? If yes, could you please suggest the same.

Thanks in advance.

Dear all, 

Any updates on this topic? Has anyone found a new source of DE81 or a reliable alternative?

Thanks, 

Miguel
