Product Description
This clever anti-oxidant gas spray doubles the life of your developer when used with black and white or colour film and print chemicals.
Based on Butane (and much safer than using lighter fuel) ,Tetenal Protectan expels air from less than full bottles of chemicals by forming a barrier layer onto of the chemicals and between the oxygen in the bottle. Keep your developer looking Champagne coloured and less like Guinness!
The 400ml can has its own spray head and is CFC free.
