Whatman filter paper question.

 Thu Jun 02, 2005 5:00 am		 Reply with quote
AFOAF has just aquired a lot of boxes of Whatman No.12 filter paper.

They may be quite old
They are marked only:

Chemically Prepared Paper
Folded Filter Papers
Made in England
No. 12 24cms.
100 circles

Trouble is he nor I can find any of the specific qualities of it online.
We've tried Google and the Whatman site and found nary a mention of it.
Does anyone know anything about it?

The #12 fluted Whatman paper from what I've been able to find is a general filter paper , high flow rate good for retention of large particles and the porosity must be around 25-30 microns similar to #4 Whatman...........java
