SP-Fixer #7 (8 oz)
SP-Fixer #7 is a low odor, rapid archival fixer. It does not require a traditional acid stop bath and is both non-bleaching and non-hardening.
It also has a neutral pH; excellent for use with PMK Pyro.
8 oz (120ml) bottle. Dilute with 24 oz of distilled water; will process over 20 tanks with the SP-445.
