Looking for donations of old film negative canisters

[Shannon Dosemagen]

Hey everyone, as you might have seen on the list, there are people in a couple different places working on developing photo paper strips for hydrogen sulfide testing. One of the things that we need for the test are black (light blocking) film negative canisters. I've met a couple of people (myself included) that save these things as they make for good storage so thought I'd ask if anyone on the list had some that they would be willing to contribute/donate to the hydrogen sulfide sensing project. Please email me at sha...@publiclaboratory.org if you have some you're willing to part with. Thanks, Shannon

I've received a couple emails back (thank you!) and don't think I was clear enough about what we're looking for. Here's a picture: http://www.ebay.com/itm/100x-BLACK-FILM-CANISTERS-with-LIDS-Wholesale-Price-/261072132351?pt=LH_DefaultDomain_0&hash=item3cc91c98ff. The clear ones can also be used, we can just wrap them in tape. 

Thanks again everyone, Shannon
