Sprint Block Stop Bath is a buffered, vanilla scented stop, which Safely and effectively stops development and adjusts the ph of b&w films and prints without unpleasant side-effects.

An indicator color signals exhaustion in b&w printing solutions. This stop dilutes in a 1-9 ratio.

Using Block: In conventional stop baths, the acid ingredient which stops development is hazardous and unpleasant to use, and can damage prints.

Acid can break down print sizing which normally protects fibers from fixer thiosulfate contamination, a major cause of deterioration.

Plain water stop baths eliminate the side-effects of acid, but do not stop development as effectively, and can cause stains and emulsion swelling and reticulation.

Block is an acid solution, but the acids are buffered to minimize the side-effects. Buffering protects print fibers for greater permanence, reduces emulsion swelling, staining, reticulation and eliminates odors. 

Block will also prevent carbonate gas ruptures of films (pinholes) when used as directed.

Block Stop Bath for Black & White Film and Paper is rated 4.6 out of 5 by 11.
Rated 4 out of 5 by from Great for starting out- I just recently started making my own prints with a second-hand setup that included a bottle of Kodak stop bath- the stuff is harsh enough I can smell it through the container! I noticed this while I was ordering some other supplies I needed and decided to give it a try instead, even in what I gather is a typical impromptu darkroom with typically suspect ventilation I generally don't know the stop tray is there unless I'm looking at it.

Rated 5 out of 5 by from Pleasant smell and easy to use I like the Sprint stop bath for two reasons. First it has a vanilla-like scent which I much prefer to the usual acetic acid smell. Second, the working solution is made by mixing the concentrate 1:9 with water, so it's very easy to mix up any amount desired.

Rated 5 out of 5 by from This is the only stop bath you should us It's safe pleasant to use and effective. Don't use the acetic acid stop baths such as Kodak. They will make you sick and they are unpleasant and unsafe to have in your work space. My opinion.

Rated 5 out of 5 by from At least it is shippable.... This is a citric acid stop. I wanted indicator stop and BH won't ship acetic acid stop anymore. I'm sure it works fine, but it is a bit more expensive per use.
