hi all,
where are forum members getting the A-D strips from at reasonable prices?
I've seen a site but it is selling packs of 250 - I only want about half a dozen or less.

I have a couple of films that I suspect have vingar syndrome but want to be sure [Confused]

Cheers

That is a GREAT question, I feel quite similarly.

Hi Dominic well there were ones from china for less will be international.

Should be something similar on any ebay site.

Just tear of and pop in the can for a day or two.

Thanks for the link, Mark. I have little doubt when I read all the negative comments for that seller but if the post and packing are cheap (I'll check that when I come back from holidays), it may Worth a try as the item itself is cheap.

Hi Dominic,
This might be a silly question but....is that link to the type of strips I need to test for VS ?
Cheers,
Clinton.

I went on the 16mm film talk forum and asked if litmus paper would do the same as A-D strips and I got this response:

"As an experiment I wanted to see what happened if I used pH test strip papers in direct contact ( for a few days ) with a very vinegar film.
The results showed NO trace of low pH ( acid ) for which the film obviously is.

Conclusion: The test strips are for liquid use only and won't work for gaseous exchange.

John S"

So the answer is NO.
