Braun Omnifix 10ml syringes are particularly well suited for measuring high dilution developers like Rodinal, Adonal and HC-110. This syringe gives super accurate measurements to .5ml increment. Perfect for measuring out 1:50 or 1:100.
These Braun 10ml syringes are made of polypropylene and are latex-free.
The Brownie Camera Guy says:
When mixing Rodinal or other 1:25 – 1:100 type high dilution developers, using a small-sized accurate syringe is the best and quickest way to measure the chemical. Then using a larger graduated cylinder is the best way to measure out the water for final mixing.
