Where can I order a small amount of filter paper for removing any small amounts of sediment in a funnel when mixing powered chemicals.

I thought Silverprint would stock but I cant find it on their website.

Any ideas?

Hi Fintan, I have plenty of various lab grade filter papers but actually prefer to use coffee filters. I have a large quantity and as I don't drink coffee they get used in the darkroom and they are ideal. Should be easy to find.

Would there be much of a difference between lab grade and the coffee grade Ian?

Yes in some ways because the lab grade papers vary in specification and their coarseness, but for practical purposes in a darkroom coffee filters are ideal, particularly as you don't need to fold them and they are fine enough to remove all you require. For instance they'll remove the suspended silver from a used Selenium toner solution.

I'll second that; I have modified a funnel with a small piece of perforated PVC, so that it holds a coffee filter, originally designed for the basket on a drip-type coffee maker. Works well for filtering out the sulfite sludge which slowly accumulates at the bottom of my 1-gallon jug of D-23.

I'm sure coffee filters will work fine, but if you want the genuine article, it's available from here in two sizes, packs of 100, cheap!

I ran a lab where we used hundreds of very fine filter papers a day. I also own a huge amount, but believe me the coffee filters are easier, and inexpensive.

There's a thing called overkill.
