|Stock Solution A
|Propylene glycol to make
|Stock Solution B
|Distilled water to make
Mixing instructions: Add chemicals in specified sequence.
Starting point development time: 5-7 mins.
Notes: Dilute up to 1+20+500 for longer development times, and increased edge effects
510-Pyro and Hypercat are highly concentrated acutance developers, designed specifically for use with their respective solvents. Both developers produce very fine grain, and full film speed, are suitable for all films and formats, and all development methods, including rotary processing. Any practical development time can be used by adjusting the developer dilution. Both developers are very clean working, producing very low fog, even when developing to the high density ranges required for UV processes. TEA and glycol concentrates are easily and accurately measured and dispensed with a measuring syringe.3ml, 6ml, and 25ml syringes cover a very wide range of dilutions and working solutions. Since these developers are so concentrated, small variations in dilution make no practical difference in the performance of the working solution, so it is perfectly acceptable to simply add the required volume of concentrate to the total volume of water. In other words, if one wishes to make up one liter of a 1:100 dilution of 510-Pyro, one can simply add 10ml of concentrate to 1 liter of water.
