Sodium Hyposulphite
hi,
I found a sack about 20kg of raw sodium hyposulphite which i believe is for mixing Fixer. Does anyone know the dilution for this chemical? thanks~! |

water ... 2liters Hypo 480grams can be used to fix a print in 30 secs but has poor keeping qualities and must be used with a acid stopbath or staining might occur do not use/keep overnight hypo. btw, it calls for Sodium Thiosulfate, not Hyposulphite which i think Hyposulphite is the old name ? thats where the name Hypo comes from right ? Care to break up the 20kg and sell some ? Lam |

Geezz! I'm getting rusty with all these stuff.... goes to show how long I've never been to the darkroom.
 Guess I have to go refresh myself.... sorry sidetracked! If I remember correctly, I use to use Hypo for fixing films, it's just that the dilution ratios are different from prints. Let me check out and see if I can get back to you on it or any gurus around who could comment? |
