I purchased a box of disposable nitrile gloves at an auto parts store, and after checking out this chemical resistance pdf, am unsure exactly how well these will protect against photographic chemicals, particularly pyro-type developers. Some advise from the more chemically literate would be welcome...thanks, Jim

Permeation and degradation rates are for "pure" or concentrated chemicals. As such, for the concentrations we use in developing nitrile gloves are excellent. One would think that if nitrile gloves are not recommended for Benzene, that this would apply for benzene derivatives like pyrogallol or pyrocatechin. This is not the case, the extra groups on the Benzene ring confer a different "chemistry" shall we say to the chemical and change the ability of the glove to resist these chemicals. If you want absolute security, you will need to get mylar gloves, but they are damn expensive and overkill for what we do.

Nitrile gloves are fine, I have been using them for years with pyro devlopers with no problems. Hell, for times of 20 min or less even latex gloves work.

Mylar gloves are best, as Jorge mentions, but they're a PITA to use. Nitrile gloves should be fine but solvents like DMF (dimethylformamide) will go right through them. This is from experience! DMF is used as a solvent in many liquid concentrate developers (HC-110, etc.)
