Inquiry, /sci/.

I'm a biologist and very badly educated in statistics, but about to write my first paper. Let's assume the following:

>Triplicates per experiment
>3 independent experiments
>each of these three experiments yields a mean value and, of course a SD for its triplicates
>journal of choice wants three experiments summed up as one value + SD.

How do I calculate the SD of three independent experiments which themselves of an SD of triplicates?

Thank you.
