Measuring tiny amounts of chemicals

This is a tip I often use with Phenidone because it is used in such tiny amounts.
- Start dissolving 1 gram of Phenidone in 90 ml of 99% pure Isopropyl Alcohol.
- When dissolved make up to liquid to 100 ml.
- This gives you a 1% Phenidone solution.
- Now, each 10 ml of the solution equals 0.1 grams Phenidone. Nice and easy!
Note: The alcohol will have no effect on the developer, film or other chemicals.
To use with other chemicals, try dissolving them in water (instead of the alcohol) to make your 1% solutions.
