Free small funnels

Hi all,

I've got some tiny funnels that are perfect for putting in the dry reagent for the Hannah Phosphorus ULR into a cuvette.


I've got about 9 of them. Located in Concord. Let me know and I can leave them for you in the mailbox.

It’s such a small amount of reagent, I’ve wondered how a variation of just a small amount of those grains of powder might effect the results of the test.
