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.

          Yes I know most people dislike the smell of stop bath. However the overwhelming VANILLA scent of this product is so bad I could smell it before I even opened the box! Furthermore it is not the product I needed. I called for assistance and this is what they sold me. Oh well, throw that money down the toilet. Not worth returning because of the cost of shipping.

            I wouldn't use any other stop bath. This product is great! I've been using this for years... maybe 10 now.

                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.

                  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.

                        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.
