Free radicals from plastic syringes.
We have found that disposable sterile plastic syringes can leach free radicals into the fluids they hold. The free radical we observe appears to be a nitroxide (aminoxyl radical) because in aqueous solution it produces a 1:1:1 three line spectrum with a hyperfine splitting constant of 16.9 G.
