Stop fix wash and rinse For best results it is recommended that all process solutions are kept at the same temperature or at least within 5 C 9 F of the developer temperature Stop Bath After development the film can be rinsed in water but we recommend that an acid stop bath is used such as ILFORD ILFOSTOP with indicator dye or ILFOSTOP PRO without indicator dye ILFOSTOP PRO is recommended for all machine processing applications When tanks or dishes trays of process solutions are in use a stop bath immediately stops development and reduces carry over of excess developer into the fixer bath This helps to maintain the activity and prolong the life of the fixer solution ILFORD Stop ILFOSTOP ILFOSTOP PRO Bath Dilution 14 19 14 19 Temperature 18 24 C 18 24 C range 64 75 F 64 75 F Time seconds 10 10 at 20 C 68 F Capaci films litre 15x 135 36 22x 135 36 unreplenished The process time given is the minimum required if necessary a longer time may be used and should not cause any process problems provided it is not excessive Fix The recommended fixers are ILFORD RAPID FIXER and ILFORD HYPAM liquid fixers and ILFORD ILFOFIX Il powder fixer all are non hardening fixers ILFORD Fixer ILFORD HYPAM amp ILFORD ILFORD RAPID FIXER _ILFOFIX Il Dilution 1 4 stock Temperature 18 24 C 18 24 C range 64 75 F 64 7 5 F Time mins 2 4 at 20 C 68 F i j Ca

Plus Generally for most applications modern camera films are sufficiently hardened at manufacture Additional hardening from a fixer hardener is not usually needed or recommended for processing in spiral tanks dishes trays deep tanks rotary processors dip and dunk hanger machines and short leader card processors unless the processing temperature is above 30 C 86 F or poor drying performance is being experienced To minimise the risk of physical damage a fixer hardener may be needed when using a roller transport film processor Using a fix hardener will require the recommended fix and wash times to be extended Depending on the film and processing conditions the hardened fix time will be between 4 and 10 minutes and the subsequent wash time 10 20 minutes in running water The amount of HYPAM HARDENER that can be added to the fixer is dependant on the film and process conditions used In some processors the full amount of hardener cannot be used as the fix and wash times cannot be extended adequately In these circumstances we recommend starting with the minimum amount of hardener to have some effect This is around 3 6 mls of hardener per litre of working strength HYPAM used This increases the film hardness slightly but has a negligible effect on the fix and wash efficiency When fix and wash times are restricted the maximum amount of HYPAM HARDENER recommended is 10 20ml of hardener per litre of working strength HYPAM
