Hi,
I am wanting to determing the density of some of my soybean samples, and in order to do that - i need to find the volume.
I know I can just grab a graduated cylinder of pure H20 and measure the displacement, but that doesn't seem very "publication quality methodology" to me.
Does anyone have an idea for obtaining the volume of soybean seeds?
Thanks for your time!

Hello Brant,
Following papers/links may help you to find appropriate method for your analysis.

Why not? I think an accurate cylinder and H2O is a scientific way to find out a subject's volume.

Water displacement is a good method. Measuring a mixed volume with the air spaces etc will give a weight which when divided against the fixed volume while not quite as accurate and precise will certainly be good as a measure and not as messy in relation to using the wet measurement. You could correlate these measurements and see if the liquid measurement actually give better measurement because it is more labor intensive. Just some thought. I have used the dry determination and it can give good information from my experience.
I agree with Paul. There are measuring cylinders available to measure hectolitre weight (kg/hL) of wheat grain samples. A test weight conversion chart is also available on internet which is being used internationally. This can be tried.
